HEMOLYMPH NODES OF THE SHEEP 
ficulty is apparently met by v Schumacher's suggestion that lymph nodes 
— among which he includes hemolymph nodes — probably continue to form 
in post-natal life. 
Then there are, of course, the structural difficulties, especially those 
concerning the venous system, and the distribution and character of the 
so-called blood sinuses of hemal nodes, said to correspond to those of 
lymph nodes, which must be met by those who maintain a conversion of 
one type of node into the other. To be sure, I am fully aware that there 
are also difficulties and interrogations to be met by those who have been 
prompted to believe in the morphological identity of hemal nodes. The 
discussion of these will be reserved for a separate article on the hemal 
nodes of Bos taurus and Capra hircus.
