HEMOLYMPH NODES OF THE SHEEP 
V. The Occurrence of Supernumerary Spleens in Dogs and Cats, 
with Observations on Corpora Libera Abdominalis. Ana- 
tomical Record, vol. 8, 1914. 
In view of the experiments of Tizzoni and other investigators of that 
period, and also for other reasons, it became necessary to possess reliable 
data regarding the occurrence of accessory spleens in dogs and cats, in 
connection with investigations on hemal nodes in the domestic animals. 
A series of careful examinations on 67 dogs and 82 cats of all ages showed 
that supernumerary spleens are present in 14.6 per cent of the cats, and 
that the number in a single animal may vary from one to approximately 
five hundred. The existence of peculiar pedunculated omental appen- 
dages — literally appendices epiploicae — was also reported, and the re- 
lation of these to the occurrence of corpora libera abdominalis discussed. 
Similarly 8.9 per cent of the dogs had supernumerary spleens, the num- 
ber per animal varying from one to over eight hundred. The bearing 
of these facts on the results of the older experiments and on the occur- 
rence of hemal nodes in these animals, is discussed critically. Several 
plates represent cross-sections and gross views of some of the specimens. 
VI. Hemal Nodes in Bos taurus and Capra hircus. (In publication.) 
In addition to a description of the hemal nodes of goats and bovines, 
special emphasis is placed on the subcutaneous and subpanicular nodes of 
Bos taurus, and on the development of the latter and of hemal nodes in 
general.
