PLATE 1 
EXPLANATION OF FIGURES 
1 Section of wall of oesophagus, showing the processes of its surface, the 
intima, the cells, and a few muscle fibers. Flemming. Acid fuchsin. 525 
diam. 
2 Transverse section through the wall of the crop, showing the cells and the 
intima, the ends of tracheae and the attachment of a radial muscle to the intima. 
Flemming. Acid fuchsin. 325 diam. 
3 Transverse section through wall of the crop, showing the result of absorp- 
tion of fatty material thirty-six hours after ingestion of olive oil. The cells 
contain many globules of osmicated fat. Flemming. Acid fuchsin. 325 diam. 
4 A later stage of the same process. The cells contain a maximum amount 
of absorbed fat. Flemming. Acid fuchsin. 325 diam. 
5 Transverse section of crop of animal which had eaten a large meal of 
olive oil two months previous to fixation; no other food was given. The cells 
contain globules of stored fat, which are being gradually broken down and util- 
ized. Flemming. Acid fuchsin. 325 diam. 
6 Section through wall of crop, showing the result of absorption of oleic 
acid thirty-two hours after ingestion. Flemming. Acid fuchsin. 325 diam.
