treating of hooping cough, we have in a note the following prescription and direction for its administration.

B. Opii Pulv. 3j.

Aq. Bullient. 3iij.

Let it stand for three hours, then strain, and add 3j. bi-carbonate of soda. Dose, for a child two years old, a teaspoonful every three hours.

If given according to the direction above, a child two years old would take the watery solution of twenty grains of opium in twenty-four hours.

What effect hooping cough may have in modifying the susceptibility of the constitution to the action of the remedy, or how far the alkali may modify its narcotic properties, we are not prepared to say; but notwithstanding our very great confidence in the experience of the author, the dose is certainly much greater than we could venture to administer to so young a subject.

We cannot close this notice without again expressing our high estimate of the work. The present edition of it, as the author has promised, has been carefully revised, and presents “a full and connected view of the actual state of the pathology and therapeutics of those affections which most usually occur between birth and puberty."

CHARGE to the Graduates of Jefferson Medical College of Philadelphia. Delivered March 25th, 1847, by Professor DUNGLISON. With a list of the Graduates. Published by the Graduating Class.

We cannot better express our own opinion of this excellent address, than by quoting the language of the able and courteous editor of the New York Annalist. "Dr. Dunglison's address is, as might be expected from so ripe and rare a scholar, highly apappropriate. Good," [and Godman]" in our own, and Park, in a sister profession are referred to as showing what can be done in the way of acquiring solid accomplishments, by enduring perseverance at the commencement of a professional career. Study, courtesy, caution, honor, &c., are all, as becomes a gentleman and a conscientious teacher, forcibly recommended to the medical debu. tante, and an eloquent and feeling peroration dismisses to the active duties of their calling, the largest class of graduates that

has ever graced the halls of Jefferson Medical College, or of any similar institution in the country.""

The following extract from the address, indicates the sources from whence the large classes of the College are drawn. Few of those who are not immediately connected with the medical institutions of Philadelphia, have an idea of the great distances from whence medical students are attracted to this city.

"You are here from regions widely distant from each othernot from Greenland's icy mountains,' but from India's coral strand'-for one of you is from remote Burmah. Representatives, too, are amongst you from Ireland, Canada, and New Brunswick, and from most of the States of this Union.

Of those on whom the degree of Doctor of Medicine has been this day conferred, seventy-two have spent one scholastic year in other incorporated institutions :-one in the Medical Department of Bowdoin College, Maine; two in that of Dartmouth College, New Hampshire; two in the Berkshire Medical Institution, Massachusetts; three in the Medical School of Castleton, Vermont; one in Geneva Medical College, New York; three in the University of New York; and two in the College of Physicians and Surgeons of that city; seven in the Medical Department of the University of Pennsylvania; and one in Pennsylvania Medical College; one in the Medical Department of the University of Maryland; and one in that of Washington University of the same state; six in that of Hampden Sidney College, at Richmond, Virginia; and fifteen in that of the University of Virginia; six in the Medical College of South Carolina; three in the Medical College of Georgia; eight in the Medical Department of the University of Louisville; and three in that of Transylvania University, Kentucky; four in the Medical College of Ohio; one in Willoughby Medical College; one in the Medical Department of the Western Reserve College, at Cleveland, Ohio; and one in the Medical College of Louisiana.

The afflux hither from other institutions must continue. It has been annually on the increase; and at no time, perhaps, has the ratio been as great as during the past session. The multiplication of medical schools, instead of diminishing the number of those that seek instruction in this city, augments it; for the facility of intercourse between the most distant places is so great, that a journey to Philadelphia is now within the means of a large proportion of medical students: hence it is, that so many visit her at least one winter, in order that they may enjoy those ample opportunities for full medical instruction, which have obtained for her the character of being the great centre of medical education on this side of the Atlantic."

THE MEDICAL EXAMINER.

PHILADELPHIA, MAY, 1847.

INHALATION OF SULPHURIC ETHER.

Our Exchange journals continue to be crowded with cases and discussions illustrative of the effects of this kind of medication. Not merely is it employed when cutting instruments are used, but in the treatment of luxations, heruia, and labour, especially in instrumental cases; in asthma, croup, and nearly all the ills that flesh is heir to. These numerous experiments will doubtless lead to a better understanding of its powers and adaptations, and it will be strange if much good does not result. Bad consequences are known to have followed the employment of the remedy in repeated instances, but the only wonder is, with such indiscriminate use of so powerful an agent, that the number of accidents has not been greater. That our readers may know something of what is said and doing on the subject, at home and abroad, we have, at the sacrifice of variety, devoted a considerable portion of the present number to extracts bearing on the most important points involved in the discussion. Already, in this country, we think we discover a decline of the excitement in relation to it, which prevailed so extensively at the first.

DELEGATES TO THE NATIONAL MEDICAL CONVENTION.

For the following list of Delegates to the National Medical Convention, we are indebted chiefly to the American Journal of the Medical Sciences. We have made some additions to the list published in that journal, but still the roll is not complete; and of those named it is not likely that all will attend, while the places of some will probably be supplied- by others. It is understood that representatives have been appointed in the States of Connecticut and Louisiana, but we are not advised of their names or how many have been designated.
