DEAR DOCTOR :-Yours at hand. It is best not to accept anything unless you pay for it. Pay in advance is always the best rule. If you haven't paid for a thing you have no right to it, and you should not allow it to be forced upon you. You should select the medical magazines that you want, pay for them, and accept no others except possibly an occasional sample copy.

Cash in advance being printed on the outside of the magazine referred to makes no difference, in my opinion. You ordered the trial subscription; are you sure there was no provision in that order for continuance unless you should direct otherwise? This is a mean way to get a subscriber, but yet, you did not act right by continuing to accept a thing that you had not and did not intend to pay for. Both you and the editor are wrong. Perhaps he can hold you by law; I am not certain and I do not care. That way of doing business, both on his side and on yours, does not deserve to prosper, and cannot lead to satisfactory business relations. Men who receive THE MEDICAL WORLD have to pay for it. When they do pay for it they get it. When the time for which they have paid expires it is stopped unless they renew; this is the only proper business basis for both publisher and subscriber.

Very truly, C. F. TAYLOR.

Reasons why every Practicing Physician should Subscribe for The Medical World.

Because it is helpful.
Because it is practical.
Because it is not pedantic.

Because it is unlike all other medical maga. zines.

Because you need it, even if you take a dozen other medical magazines.

Because, if you subscribe for only one medical magazine, that one should be

THE MEDICAL WORLD.

Because it is like a chat in your office with your co workers in all parts of the country. Because it is like a medical society meeting in your office every month.

Because it helps you to work out your problems at the time they arise.

Because special attention is given to troubles most likely to arise during each particular season; as lung troubles in winter, bowel troubles in summer, etc.

Because, in it, the tired doctor finds a friend and helper.

Because it publishes no long, tedious and

theoretical articles. and no "perfunctory" sotiety reports.

Because everything in it is brief and practical.

Because it is a post-graduate school, which you do not have to leave your home to attend -it comes to you.

Because it is the medium of exchange of thought among the members of the profession in all parts of the country.

Because it is of the profession, by the profession, and for the profession.

Because it belongs to the hard workers in the ranks.

Because it discusses the financial as well as the scientific interests of the profession.

Because it helps doctors to collect their bills as well as to cure their patients.

Because there are many other reasons too numerous to mention.

Some of the reasons that keep The Medical WORLD from thousands of physicians' offices:

Because you don't like to write a letter.

Because you haven't time to go to the post office to get a money order, but you think you will have time this afternoon, but something else comes up to take your time,

Because you think you will do it tomorrow, and so you put it off from day to day. Because you are always going to do it, but never do it.

Because you think you will but you don't. Because, because, because, and you go along from day to day. wanting THE MEDICAL WORLD but never getting it.

The way to do it is to do it-and do it now. If not at this moment, keep this before you until it is done.

WE are responsible for money sent by P. O. money order (which only costs you 3 cents) or registered letter. However, a dollar bill carefully sealed in a letter and properly directed usually reaches its destination safely, but we cannot assume the risk; you may if you wish. Many do. Other safe ways of sending are by express and by bank draft. Personal checks are not so desirable, but we always take them -yes, and postage stamps too. You don't need to write a letter. Just inclose $1 and we will know that you want WORLD for 1898. Write name and address plainly, or use printed stationary, or inclose printed card.

AMONG the many favorable letters received by Smith, Kline & French Co., manufacturers of Eskay's Albumenized Food, particular attention is drawn to the fact that in many cases Eskay's food was prescribed only as a last resort, and in almost every case marked favorable results were noted. Of course as a new food for infants and invalids, it will be subjected to the severest tests, and it is certainly gratifying to note that thus far the results have been highly satisfactory both to physician and manufacturer. It succeeds where other foods fail.-Send for sample.

SINCE the "six iodides," "six bromides, " "six aperiens," "six hypophosphites" have come into general use by physicians, we hear less and less about "scrofula," "nervous prostration," ""constipation" and "that all gone feeling."

WM. C. BOTELER, M. D. Professor of Ophthalmology, in the College of Physicians and Surgeons, Kansas City, Kas.

Dr. Waugh's applied therapeutics came safely to hand. My admiration for Dr. Waugh for many years has been great, and year by year my high appreciation of his discriminating powers, his wonderful memory and vast research increases. His "Treatment of the Sick "will be my reference book from now on. I have been in harness nearly four decades, but had I time and opportunity would go under his teaching for a while.

If a physician ever finds it necessary to resort to predigested food to supply nourishment in an immediately assimilable form to sustain life, he will find Armour's Nutrient Wine of Beef Peptone the ideal preparation. Nutrient Wine is made from lean beef predigested and sterilized and a good, sound sherry. Each ounce contains the entire digestible substance of one ounce of lean beef.

Of the three hundred and over public institutions, such as asylums, dispensaries, hospitals, homes and infirmaries in New York, one hundred and six are using Unguentine daily. It is a staple with them, thus showing a most deserved popularity. In fact, it is fast becoming the dressing for all ailments where there is inflammation.

THE importance of a support for the abdo men, particularly in advanced pregnancy, cannot be overestimated; and if every physician realized its importance there would be a much greater demand for suitable appliances than now exists. The most approved abdominal supporter for pregnancy, and for support after operations of laparotomy, appendicitis, or any weakness of abdomen, are made by G. W. Flavell & Bro., 1005 Spring Garden street, Philadelphia, who solicit your patronage direct, assuring a prompt and satisfactory execution of all orders entrusted to their care.

THE law of many states requires the obstetrician to use prophylactic measures to save the sight of newly born infants. A safe, harmless and positive procedure is the thoro cleansing of the conjunctiva with a 25 per cent. solution of "Palpebrine " and the application of a few drops full strength into the eyes shortly after birth. Many physicians make it a routine rule to use "Palpebrine" even if there is no evidence of liability to infection. "Palpebrine" is an antiseptic, germicide an slightly astringent solution. The Dios Chemical Co., St. Louis, will mail sample and formula on application.

THE most recent addition to our literature on the antitoxin treatment of diphtheria is easily the most complete and comprehensive yet issued. It is literally a multum in parvo production, and should be in the hand of every physician in the country. It is an entirely new brochure entitled, "The Present Status of Diphtheria Antitoxic Serum," and was recently issued by H. K Mulford Company, of Philadelphia and Chicago. The brochure gives in addition to a brief summary of the methods of producing antitoxin, a complete treatise on how to employ the remedy, a resume of what writers of recent text-books say of the treat(Continued over next leaf.)

The Determination of Sex.

The sensational prominence given by the newspapers to the alleged discovery of Prof. Schenk, of Vienna, concerning the determining of sex, is out of proportion to the importance of what the Professor has to offer on the subject. The gist of the matter is this: In the human being, the corpuscles in the blood exist in the proportion of five millions in the male to four millions in the female. To produce a male, he seeks to increase the number of corpuscles in the prospective mother to the male standard; to produce a female the opposite course is taken. He does not give his modus operandi, but that is his principle. It has long

the prospective mother would favor the production of males, and low feeding would favor the production of females. Professor Schenk brings the matter down to greater nicety, but the idea is not a new one. We will await the announcement of his method to see if there is anything new in that. There is still a difference of opinion among embryologists as to the time that sex is determined. Some still think that the sex of the future being is determined at the moment of contact of the male and female elements. If this be true, subsequent nutrition could make no difference. Others hold that the sex is determined during early development. If this be true, nutrition might be an important factor in determining the sex.

"Beware of the Ides of March."

March WORLD must receive our immediate attention, for it must be prepared, printed and mailed during February, the shortest month of the year. During March the winter "breaks." It is the most bleak and changeable month of the year. It marks the high tide of the "season" in Florida, for those who can, wish to flee from what is the most disagreeable weather of the year in most other sections of the country. During this month winter and spring struggle for the mastery. While the latter is always victorious, yet winter sometimes then deals his heaviest blows. The memorable "blizzard" of 1888 with such heavy snow thruout the Atlantic States occurred in March. All sorts of lung troubles continue, this month being particularly hard on tuberculous people who have been struggling thru the winter, but the blasts of March cut them down.

It is the banner rheumatism month of
