SUMMARY OF EQUIPMENT AND MATERIAL 141 
Dissections of cats or other mammals to show the brachial 
and lumbosacral plexuses in situ. 
Dissections of cats or other mammals to show the chain 
sympathetic ganglia and their connections with the visceral 
divisions of the spinal nerves. 
Dissections showing the brain of the dogfish, and of other 
vertebrates, particularly the more primitive classes in situ. 
Dissections of cats or other mammals with circulatory system, 
injected, for comparison with those forms used in the laboratory, 
or as a substitute (if time is limited) for specimens injected by 
individual students. 
Dissections of cats, rabbits, or other mammals to show the 
relationships of the various parts of the digestive system. 
Dissections of cats and rabbits to show the urogenital systems 
of males and females of each species. 
Preparations of gravid uteri, preferably of some Primate. 
Sets of mammalian embryos of various stages (pig embryos are 
readily obtainable), for the study of the development of external 
form. 
A series of human embryos of different stages, some, at least, 
with the placenta and other extraembryonal parts attached. 
Miscellaneous preparations, especially of parts of the human 
anatomy, such as dissections of the tongue and larynx, heart, 
etc. 
IV. SLIDE COLLECTIONS. 
Sets of slides (laboratory slide collection) in sufficient numbers 
to supply individual students of a laboratory division. The 
following are suggested as desirable: 
A. Mitosis in tissue cells. 
1. Growing tips of onion root, longitudinal sections, stained 
with iron haematoxylin. 
2. Epidermis of salamander, surface mount, conjunctiva of 
eye, stained in haematoxylin or safranin. 
B. Epithelial tissues. 
1. Simple epithelium. 
(a) Cuboidal: sections of gall bladder of Necturus.
