medical department of an army, modes of transporting sick and 
wounded, hospitals, medical supplies, instruments, ete. 3. Human 
anatomy and pathology of both sexes and all ages. This requires 
many specimens in comparative anatomy and pathology, which are 
indispensable for a correct understanding of the structure, develop- 
ment, abnormalities and diseases of man. It is not however proposed 
to form a museum of comparative anatomy—that belongs to the 
functions of the National Museum. 4. To show the morphologi-

pometry and craniology. 5. To illustrate for medical investiga- 
tors and teachers the latest methods, the newest apparatus, etc., for 
biological investigation, and various modes of preparing and mount-

dissections under spirit, frozen and tinted sections, injections by cor-

specimens were explained.

osteological specimens. The papers were all fully illustrated by 
specimens from the Medical and National Museums.
