consisted chiefly of mucus. In point of fact, the globule is en- 
tirely held together by the mucous secretion of the rumen. 
Although the animal had drunk a little while before it was 
slaughtered, no fluid in any quantity existed in the paunch. 
Nothing can more favour the formation of the pellet than the 
mucus secreted by the spiculated tunic of the rumen, in conjunc- 
tion with its semi-revolving action. 
The omasum . — The contents of this viscus consisted of food 
in a more fluid state ; but not a single pellet was found there. 
Now, if the pellet of rumination is formed in the second 
stomach, how is it that no globules were perceptible ? Besides, 
according to the opinion of some, the second stomach is for the 
reception of water; but water mixed with the ingesta would not 
be of sufficient tenacity to mat the pellets together, mucus 
being necessarily required to make the particles of heterogeneous 
food adhere in a mass. The food in the rumen was loaded with 
mucus, and that in the omasum was watery and thin. The 
quantity of pellets in the rumen may be thus explained : the 
globule, not being able to be ejected by the cesophagean canal 
through the oesophagus, fell back again into the rumen or first 
stomach. 
The mauiplus, or third stomach, was empty ; its leaves were 
in contact, but moist from its normal secretions. Its papillae were 
visible and erect. 
The abomasum, contained a verdurous fluid and seemed healthy. 
The intestines were empty, except the rectum, which contained 
a small quantity of faeces. I have detailed this case as minutely 
as possible through the medium of The Veterinarian. If, 
instead of many of our professional brethren recording their 
cases in their private manuscripts, they would suffer them to 
appear in type, they would repay our standard work for its 
candour, its fairness, and its diffusion of right and honourable 
principles. 
ON THE IDENTITY OF RED-WATER AND SERUM. 
Bi/ Mr. R. Read, Crediton. 
Having in the January number of The Veterinarian as- 
serted an opinion that the bloody water in cattle was constituted 
partly of serum, and its colour modified by an excess or want of 
cruor, in a chemical combination with the urine, the following 
experiments are detailed as presenting similar results : —
