128. EGGS, and a series of EMBRYOS of the LOGGERHEAD 
TURTLE ( Thalassochelys cavetta), showing stages of growth for 
every five days during the period of development in the egg. 
The Loggerhead Turtle of our South Atlantic coast reaches a 
weight of five hundred pounds. Its eggs are laid during the 
summer on the sea beach in a hole dug by the Turtle. Some 
one hundred and fifty eggs are deposited. They hatch at the 
end of the sixtieth day, and the young Turtles at once make 
their way to the sea. The specimens shown were collected by 
Mrs. F. E. B. Latham, at Micco, Florida.

New York City. (See Bull. Am. Mus. Nat. Hist., vol. vi., 1894,

131. CORTEX OF HUMAN CEREBELLUM. A section of the human 
cerebellum, showing: (1) the outer or molecular layer; (2) the 
row of Purkinje cells, with the coarser of their protoplasmic 
processes extending towards the periphery; (3) the granular 
layer ; and (4) the innermost layer of fibres. This preparation, 
made by Dr. Piersol and kindly loaned by Dr. Van Gieson, is 
stained with carminate of soda and shows about all the details 
that can be shown without the aid of the Golgi preparations. 
132a. PURKINJE CELLS OF THE ADULT HUMAN CEREBELLUM. 
Preparation showing the protoplasmic processes filling the outer 
or molecular layer of a sulcus of the adult human cerebellum. 
1320. NEUROGLIA OR “SPIDER” CELLS OF INNER LAYERS OF 
HUMAN CEREBELLUM. The heavy black branching processes
