The bulletin board is at the right of the window.

paper makes for us a carbon copy of all telegraph news and hands it to our messenger when he calls at the office every hour. We read the copy carefully, pick out important news only, and give just enough details to satisfy the public.

BEATING OUT THE CITY PAPERS.

After 3 P.M. we get a special news telegram whenever a large story comes to light in any part of the world. By 7 o'clock at night we have covered most of the news that will appear in the large city dailies the next morning.

Important events, in which much local interest is shown, we cover in detail. On many occasions the bulletin sheets close up the entire front of the windows with the exception of a small space at the bottom through which the goods on display may be seen.

Besides giving the news service through the medium of the bulletin we are ready at all times to answer telephone calls concerning elections, baseball scores, athletic contests, location of fires, and all news in general.

When the fire alarm sounds our 'phones start to ring even before the alarm is finished, for the people know that our system of newsgetting has already located the fire. On numerous occasions we have had fires posted on the

bulletin even before the alarm was sent in. When our city suffered a $150,000 loss on July 18 of last year, we had the notice up twenty minutes before the first alarm came in.

During the World's Series we get the baseball returns, play by play, over a special field wire, having the exclusive service for the entire county. Western Union service furnishes us with details of all special automobile races, and when any of our local athletic teams are contesting away from home we give the details as fast as they can come over the wire.

HOW THE SERVICE HELPS BUSINESS.

It might seem that after furnishing the news in such detail we would have no time to attend to our drug business. This, of course, is not the case, for the whole object supplying the news service is to attract customers to our store. That we get the business is evidenced by the fact that in the State of Ohio our store stands tenth in point of sales on Rexall goods. And our town has a population of only 14,000 at that.

News collecting requires no special clerks. It ordinarily takes but a minute to run down a story over the telephone. In the special cases where the telephone plan will not work a

on our window each day. These in many instances connect up with news items which appeared on the bulletin several days before.

2. We receive the weather forecast each day at 8 A.M. and at 6 P.M. from the local telegraph office and place it, neatly typewritten, in a glass case where it is easily accessible. The government weather map is also received at 6 P.M. each day from the government weather forecaster. This map gives the direction of winds, the temperature of all United States cities at 8 A. M. on that day, the stage of the water in the

CAMBRIDGE PEOPLE. Free Prescriptions for Entire Year 1916.

Any reputable physician is authorized to send worthy poor persons to our store for prescriptions during the year 1916, and we agree to fill them without cost. Nothing is required but a note from the physician, properly signed and stating that the patient is entitled to this assistance.

In this manner we aim to contribute our share toward the public good. Instead of responding to countless requests for little contributions to programs, fairs, and bazaars, among which we cannot discriminate, we have adopted this plan.

Let no worthy man, woman, or child suffer a moment for want of proper medicine when required.

this instrument is furnished us free by a tobacco firm in West Virginia.

The registration of our thermometer is the town topic on a cold morning as it is the recognized standard for the vicinity. Many 'phone calls are received daily from housewives who wish to compare their home thermometers with our tested instrument.

4. We use the last sheet on our bulletin for want ads "Lost and Found" and "Help Wanted." No charge is made for this service, through which many valuable articles are returned to their owners, and through which we get dozens of pleased customers for the store.

To show the effectiveness of this sheet as an employment bureau: At 1 P.M., on January 10, our Western Union operator asked me to post a notice that he wanted a messenger boy. At 1.45 P.M. he called again, saying: "Take down that notice! I have had seventy-five applications in person already, the office is crowded to its capacity yet, and all I need is one boy."

5. A large clock regulated hourly by Western Union occupies a prominent position in the doorway.

LOCATING FARMERS "WANTED AT HOME."

6. Under the clock we run a "Wanted at Home" bulletin which is used mostly by farmFor example, if we put out a notice that John Smith is wanted, some of his friends soon read it and it is not long until John is headed for Wilson's drug store to find out for what he is wanted.

7. A large map of the city, framed in glass, is found in our doorway. We direct people to different parts of the city by this map.

8. A county road map shows all county roads, their conditions, what they are made of, etc.

9. We sell theater tickets, displaying a large sign to call attention to the fact.

10. Numerous signs bearing the store name appear in conspicuous positions, helping to fix our establishment in the minds of the people as "the spot to buy everything in the drug line."

11. Displayed in several places on the store front is our free prescription offer, a reproduction of which is shown on this page.

The upper background was built over wire bent into arch effects, the framework being covered with heavy paper. Over this there was a series of white tissue puffing.

Running along the entire border, and placed about ten inches apart, were a number of circular gold cut-outs.

There was a little latticework, as may be

dow a positive selling appeal. I always use show-cards and price-tags-or a combination of the two, rather.

To attract attention, a captive balloon was properly picketed. A little motion in the window is a great thing.

BOARD QUESTIONS ANSWERED

AN INDIANA EXAMINATION.
(Continued from the February BULLETIN.)

26. Why is diluted hypophosphorous acid used in the preparation of syrup of ferrous iodide?

Hypophosphorous acid, being a valuable reducing agent, is added to prevent oxidation and consequent discoloration of the syrup.

27. How much potassium iodide will be required to make 2 ounces of a saturated solution? (The solubility of potassium iodide is .7.)

are

If by "ounces" avoirdupois ounces meant, the problem may be worked out as follows:

One avoirdupois ounce of a saturated solution is composed of one part of potassium iodide and 7 part of water. Therefore in 437.5 grains (1 avoirdupois ounce) there would be 10/17 part of potassium iodide or 257.4 grains.

If, however, by "ounces" fluidounces is meant, the problem cannot be worked out from the data given. It is impossible to tell except by experimentation what volume will result when ten parts of potassium iodide are dissolved in 7 parts of water. In common practice, however, we might say that five fluidrachms of water added to an apothecaries' ounce of potassium iodide will produce a fluidounce of solution that contains one grain of potassium iodide in each minim.

28. (a) What difficulties are encountered in the manufacture and dispensing of Goulard's solution and lead water? (b) How may trouble be prevented?

(a) On exposure to air, the preparations absorb carbon dioxide, which causes the formation of a white precipitate of lead carbonate. Even mixing with distilled water which has absorbed carbon dioxide from the atmosphere will cause the precipitation.

(b) By keeping the preparations in wellstoppered bottles, and preventing access of air, the trouble may be avoided to a great extent.

29. Give the drug strength, medicinal action, and dose of five potent tinctures.

Tincture of opium represents 12 to 12.5 grammes of crystallizable morphine in 1000

Cc., is a stimulant narcotic, and the average dose is 8 minims.

Tincture of nux vomica represents 1 gramme of strychnine in 1000 Cc., is a tonic and systemic stimulant, and the average dose is 10 minims.

Tincture of Indian cannabis represents 100 grammes of Indian cannabis in 1000 Cc., is a powerful narcotic, and the average dose is 10 minims.

Tincture of gelsemium represents 100 grammes of gelsemium in 1000 Cc., is a motor and respiratory depressant, and the average dose is 8 minims.

Tincture of stramonium represents 0.25 gramme of mydriatic alkaloids in 1000 Cc., is an antispasmodic, and the average dose is 8 minims.

CHEMISTRY.

1. Name ten elements, giving symbols, tell whether metallic or non-metallic, also whether a solid, fluid, or gas at ordinary temperature. Aluminum, symbol Al, is a solid metallic element.

Gold, symbol Au, is a solid metallic element. Sodium, symbol Na, is a solid metallic ele

ment.

Mercury, symbol Hg, is a liquid metallic ele

ment.

Bromine, symbol Br, is a liquid non-metallic element.

Sulphur, symbol S, is a solid non-metallic element.

Carbon, symbol C, is a solid non-metallic element.

Oxygen, symbol O, is a gaseous non-metallic element.

Chlorine, symbol Cl, is a gaseous nonmetallic element.

2. Briefly describe three elements, one a solid, one a fluid, and one a gas, telling their characteristic physical and chemical properties.

(a) Aluminum is a solid, silver-white metal, malleable and ductile, capable of high polish. It is not tarnished in the air. Its specific weight is 2.5. It is not easily attacked by dilute acids. Hot solutions of fixed alkalies dissolve the metal with formation of aluminates.

(b) Mercury is a silver-white, lustrous, and mobile metal, liquid at common temperatures. Its specific weight is 13.6 and it boils at about 360° C. It freezes at about -40° C. Mercury does not readily enter into combination with

oxygen at the common temperature, and it does not exhibit any great chemical energy. Its compounds are generally unstable; many of them are decomposed by light.

(c) Chlorine is a yellow-green gas of suffocating characteristic odor, poisonous when inhaled in considerable quantities. At 15° C. it can be compressed into a liquid under the pressure of four atmospheres. The molecule of chlorine is diatomic at lower temperatures; but monatomic at higher temperatures. Chlorine unites with most other elements.

No

3. What is a chemical symbol? A chemical symbol is an abbreviation representing the atom of any given element. two different kinds of atoms are represented by the same symbol. The symbols used consist of letters. These letters are the single initials of the latinic or other names of the elements, or the initial letter accompanied by one additional in some cases where the latinic names of two or more elements begin with the same letter.

4. What is meant by a chemical formula? A chemical formula is a combination of one or more symbols together with one or more numerals, or of two or more symbols, with or without numerals, expressing the composition of free atoms, compound radicals, or molecules. 5. What is meant by atomic weight?

The mass of one atom of any element is the atomic weight of that element. The atomic weights are the smallest relative masses of elements entering into combination with other elements.

6. What is meant by molecular weight? Molecular weight is the sum of the weight of the atoms contained in a molecule.

7. What is meant by a chemical equation? A chemical equation is an expression of a chemical reaction by means of the symbolic molecular formulas of its factors and products.

8. What are the correct names of the following: (a) muriatic acid, (b) copperas, (c) blue vitriol, (d) green vitriol, (e) white vitriol, (f) cream of tartar, (g) salts of tartar, (h) tartar emetic, (i) Epsom salt, (j) Rochelle salt.

(a) Hydrochloric acid, (b) ferrous sulphate, (c) copper sulphate, (d) ferrous sulphate, (e) zinc sulphate, (f) potassium bitartrate, (g) potassium carbonate, (h) antimony and potas

sium tartrate, (i) magnesium sulphate, (j) potassium and sodium tartrate.

9. What is (a) a neutral salt, (b) an acid salt, (c) a double salt?

(a) A neutral salt is one formed when all the hydrogen atoms of the acid are replaced by a metal.

(b) An acid salt is one in which all the basic hydrogen atoms of the acid are not replaced by metal.

(c) A double salt is one formed when two or more of the basic hydrogen atoms of an acid are exchanged for two metals.

10. How would you fill the following prescription, supposing you were out of sodium salicylate, but with plenty of salicylic acid and bicarbonate of soda at hand?

Sodium salicylate....5 drachms, 18 grains.
Water, q. s. ad..
...8 fluidounces.
How much of each would be required?
Sodium salicylate is formed as follows:

HCHO,+NaHCO,=NaCHO+H_O+CO,.

The molecular weight of salicylic acid is 137.01; of sodium bicarbonate, 83.43; of sodium salicylate, 158.89. Therefore 137.01 parts of salicylic acid and 83.43 parts of sodium bicarbonate are required to produce 158.89 parts of sodium salicylate.

5 drachms, 18 grains=318 grains.

318 grains is practically equivalent to 2 times 158.89 grains.

Therefore 274.02 grains of salicylic acid and 166.86 grains of sodium bicarbonate are required to produce 318 grains (317.78 exactly) of sodium salicylate.

The prescriptions should be compounded as follows:

Shake the salicylic acid with 6 fluidounces of the water so as to distribute it uniformly through the liquid. Then add the sodium bicarbonate, a little at a time, shaking well after each addition. Warm the liquid slightly to expel the carbonic acid which is set free. Filter and add sufficient water to make the volume measure 8 fluid ounces.

In practice it is better to use a slight excess of salicylic acid, in order to prevent darkening of the product.
