the fluid element. The coagulability of the lymph appears to bear 

 a close relation to that of the blood in the same animal. 



Lymph, The liquid portion, liquor lymphce, is supposed by 

 some to be simply albuminous in the primary network, and to 

 acquire its fibrine on its passage onwards through the vessels and 

 glands towards the veins. The fibrine is found in increasing 

 quantity towards the main trunks, though never in so large a 

 proportion as in the liquor sanguinis. The same kind of saline 

 matters are also met with in the liquor lymphse as in the liquor 

 sanguinis, together with a trace of fatty substance and some 

 iron. 



The lymph corpuscles are very scanty in the primary network 

 *V-n2. and branches (as already 



noticed in the observa- 

 tions of Kolliker), and 

 they increase in number, 

 and perhaps in size, to- 

 wards the trunks, espe- 

 cially as they pass the 

 glands. They present 

 themselves under some 

 varieties; in one, and 

 this is the most usual, 

 the nucleus is concealed 

 by a granular matter ; in 

 another, this granular

coarse in the largest ones, but almost entirely disappear under 



the action of acetic acid, which thereby discloses an appearance of removal Or 



of one or two nuclei. The majority of the corpuscles are either 



large or small, and but few of intermediate size. d. Exhibits CCnCC, SO that the

 corpuscles are called by Mr. W. Jones respectively the granule- 

 cell and the nucleated cell in the uncoloured stage, and he further 

 points out that there are in the lymph other nucleated cells 

 approximating in colour to the red-corpuscles of the blood, and 

 which he regards as in progress to become red blood corpus- 

 cles, by losing their cell- wall, and becoming reduced to a simple 

 nucleus.*
