This volume, according to Deputy Surgeon-General D. L. Huntington, includes 6,346 author titles, representing 6,127 volumes and 6,327 pamphlets. It also contains 7,884 subject titles of separate books and pamphlets, and 30,384 titles of articles in periodicals. The value of the Index-Catalogue to medical science can not be over-estimated, and it is pleasant to know that the work is appreciated in Europe as well as in America. Congress, in making annual appropriation for this work, has acted wisely.
The arrangement of the volume is the same as that of the first series.
