“The Phone of a Thousand Ears.”—
Educating customers to the use of the telephone is a means adopted by G. M. Chatfield, of Montgomery, Alabama, to build up his business. He has adopted as one of his slogans "The Phone of a Thousand Ears Hears the Phone of a Thousand Voices.”
Here is one of the newspaper advertisements used by Mr. Chatfield to call attention to his service:
"Chief among the attributes of good counter service," said Orrin O. Bigelow, at the 1915 meeting of the New York State Pharmaceutical Association, “is the personal touch, the desire to satisfy the customer by fulfilling his or her wants.
"The clerk who sells a one-cent stamp, calls a number on the phone, or gives information about trains with the same readiness and courteous treatment with which he makes a large sale is certainly serving his employer much better than the one who does not.
“That same clerk, however, may have the desire for service so inbred and so enlarged that when the inspector for the State Board of Pharmacy drops in, while the boss or licensed man is out to lunch, and calls for a 2-inch bandage and a bottle of carbolic acid, he either forgets or puts aside limitations, makes the sale, and gets the boss in trouble.
"Another time when this desire to please becomes overgrown is when a clerk overreaches his authority and either makes a special price or gives away an article of value to please and gain the friendship or personal patronage of the customer.
"Counter service calls for a large amount of good judgment. A day laborer would be bored if served with the same politeness accorded an aged invalid woman.
"One feature which we practice, as far as possible, is to hand women good clean bills with their change, and I know of cases where this small feature has won friends to our store. Making oneself agreeable to pessimistic and disagreeable people is also a to-be-triedfor attainment in this connection.
"Neat, well-wrapped bundles and polite counting of change both help. A pleasant 'Good morning' or 'We shall be pleased to serve you at any time,' or 'Will there be something else?' or any of the other pet phrases seldom lose their efficiency when given with an intent to please."
THE PHONE “OF A THOUSAND EARS”
When the phone "Of a Thousand Voices" empties its great volume into the phone “Of a Thousand Ears," a wonderful transformation immediately occurs. The stream is resolved into its integral parts and each voice is heard distinctly and clearly.
The phone “Of a Thousand Ears" hears each voice and listens courteously to every sound. It ascertains the exact wants of each voice and then sets in motion the wonderful Chatfield system of quick, rapid-fire delivery that distinguishes this service from all others.
An Advertisement for the Prescription Department.
"The Co-Operator," published in the interest of retail merchants by the Chicago Tribune, suggests the following text for display cards or circulars, to be used by pharmacists, says the British Columbia Pharmaceutical Record. Each pharmacist may alter the advertisement to suit his particular neighborhood :
Science and Skill in Prescription Filling.—The ingredients that enter into your prescriptions play an important part, but the way these ingredients are mixed is equally important.
Science, as well as skill, must be brought to bear on every prescription, if the best results are to be expected. The patient deserves the best results, also your doctor. Your prescription represents our skilful conipounding and the results of modern scientific advancement. We solicit the opportunity to fill your prescription.
We certainly do try to please every customer. We realize the uselessness of getting customers and not
Creating Sales Opportunities.
Creating favorable opportunities for opening a sales talk is the hobby of a druggist whose store is located in a middle-western city.
He has one scheme that is particularly effective for getting a prospective customer interested in safety razors.
Right on top of the cigar counter this druggist keeps a small display case of the razors. But instead of having the razors neatly arranged in the case, one is always out on the counter. It is out of the box, and some of the literature concerning it is handy by.
When a customer approaches the cigar counter the clerk behind it is apparently busy with the razor, preparatory to replacing it in the case. Still with the razor in his hand, the clerk hands out the desired smokes and then launches into his demonstrating talk.
He goes at it something like this:
"By the way, Mr. - you might be interested in looking over this safety razor before I put it back in the case.”
Then he swings into a description of the merits of
the razor and succeeds in interesting the prospect frequently enough to make the apparently by-chance method of attracting attention decidedly worth while from a cash register standpoint.
A Store Catalogue in a Newspaper.
Putting a complete drug-store catalogue in the hands of its customers through a series of newspaper advertisements is the plan adopted by the Warner Drug Company, of El Paso, Texas.
A full-page space is taken in a local paper from time
to time, and in it are listed all the goods of various lines carried by the store. As can be seen by the accompanying reproduction, many of the items listed are illustrated by cuts.
Part of the space is devoted to exploiting the company's mail-order department.
By saving the advertisements as they appear the customer eventually acquires a comprehensive price-list of all the merchandise offered by the store-a list that will be of much practical value when it is desired to order goods by mail.

L. Mennier finds that the dilution of medicines is an important factor in their action, particularly in the stomach. He states that when the solution is isotonic, having a freezing-point depression of 0.350, it passes through the stomach more rapidly and in larger amounts than more concentrated or more dilute solutions, hence causes less gastric disturbance.
A Color Preservative.
Professor Greenish says that darkening in solutions of sodium salicylate in presence of an excess of alkali can be prevented by adding a little sodium sulphite or bisulphite. Only a very little is required-about one per cent of the sodium salicylate present. The darkening is most rapid in solutions containing sodium bicarbonate or sesquicarbonate, and is promoted by the action of air. Sodium carbonate or hydroxide does not darken the salicylate as rapidly or as deeply.
The commercial production of liquid air is increasing rapidly and machines are made which are capable of making 30,000 gallons per hour. The chief uses are for the production of pure oxygen or nitrogen and of neon, the latter being used for filling electric light bulbs.

After sterilizing in steam for thirty minutes, a 2-per-cent solution of morphine sulphate should remain colorless, or show at most only a pale yellow color after 24 hours; a 0.5-per-cent solution of strychnine nitrate should deposit no crystals; a one-per-cent solution of mercuric chloride should develop no colored oxide; a 0.1-per-cent solution of narcotine hydrochloride should show no flocculent matter after one hour; and 2 or 3 drops of phenolphthalein in 100 mils of distilled water should show only a pale rose color after 24 hours.
G. F. Becker says that "if the level of isostatic compensation is as deep as 140 kilometers, and if this is also the eutectic level, then the earth must be 100 million years old, the radioactive layer can be only 4.74 kilometers thick, and 26 per cent of the heat emitted by the earth is of radioactive origin."

Florida and Texas will add camphor to their important products in the future, thousands of trees having been planted in each State. Florida produced 10,000 lbs. of camphor last year. The yield increases with the age and size of the trees, and 50 years is a conservative estimate of the time required for large returns.
A True Hair Tonic.
Dr. Josephson says that loss of hair is probably caused by a deficiency in secretion of some endocrinous gland. In children the administration of thyroid often results in an increased growth of hair. In adults the thyroid, the pituitary gland, the reproductive glands, and the suprarenal gland all appear to play a part, and if we could determine which one is deficient the treatment of baldness in all its degrees would probably be a simple matter, with uniformly beneficial results. To determine which gland is deficient is not, however, an easy matter.
Two German chemists, Traube and Onodera, state that certain alkaloids of high molecular weight, such as atropine and quinine, are more poisonous in alkaline than in acid solutions. This is due to the free alkaloid being in colloidal solution, while the salts form true solutions. The surface tension of the water is reduced by the colloidal solution, but is scarcely affected by the true solution, and the reduced surface tension promotes the absorption of the alkaloid and increases the intensity of its action. It is thought that any alteration of the surface tension disturbs the equilibrium and affects the normal velocity of reactions in the organism, thus increasing or diminishing the toxic effect. With alkaloids especially the alteration in surface tension is the chief factor in toxicity, their action being more physical than chemical. It is further suggested that the localizing of action of various alkaloids may be due, in part at least, to a varying alkalinity in the different organs of the body.
