I am aware that it may be objected to this plan that it gives the student little more than a parrot like command of a few words and expressions, and does not teach him the principles of the language. But I respectfully submit that it is far better for a man to write a prescription correctly, even in the most automatic way, than to blunder through it dis gracefully, as so many habitually do, and thus expose himself to the ridicule of apothecaries' shop-boys. Besides, I cherish the not unreasonable hope that the aid in prescription writing derived from the little knowledge of Latin which this book may im part will so convince some students of the value of the language, that they will systematically undertake the mastery of its elements, and acquire a consider able vocabulary. The time is not very far off, I trust, when no one will be allowed to matriculate in a medical school who has not a good reading knowl edge of easy Latin. Until then, it seems to me that such books as this is designed to be may perform an important service.
