Professor Wall states in the preface of this volume that "the elementary principles of the Latin language contained in this little book are sufficient to enable the student to read the Latin edition of the German pharmacopoeia, which is as much Latin as is necessary for the pharmaceutical or medical student." He might have added that it is far more than the average student of these professions ever acquires. The majority of pharmaceutical students and many medical students enter college with no training at all in Latin, and in the limited time which can be devoted to this subject in college a knowledge of only a small portion of the grammar can be gained, and the study of Latin is limited to those forms and principles which are absolutely essential to enable the student to understand Latin titles and prescriptions. Professor Wall's treatment of the subject is therefore much more complete than is found in the ordinary textbook on pharmaceutical Latin.
