Excerpt from Elements of Medical Zoology At the present time there is no standard work in the English language upon Medical Zoology, the only book especially devoted to this subject being Dr. Stephenson's Medical Zoology and Mineralogy, which was published as far back as 1832. The numerous treatises on Materia Medica refer only to those animals which are employed as remedial agents, while the writers on practical medicine seldom give more than a mere outline of the Entozoa and of those Animals which are injurious to man. The work of M. Tandon contains a more complete account of the Human Entozoa, and of those Animals which are either ih jurions or beneficial to man in a medical point of view, and is furnished with a larger number of illustrations, than any previous publication on the same subject.
