WHEN “Martindale” was divided into two volumes on the issue of the fifteenth edition in 1912, the dividing line ran roughly between drugs used in the treatment of disease, which were dealt with in volume 1, and an account of recent therapeutical research which, with much bacteriological, analytical, and other information of value to medical men and pharmacists, composed volume 2. This arrangement, which has proved convenient in practice, is still maintained, and as this is the third edition published since the division took place, it is clear that in its new form the book has lost none of its popularity.
