cut and scraped from the carcase after the hide is taken off. The 
formation of this matter must be a great drain on the health, con¬ 
dition, and quality of the animal, and must be a great loss to 
somebody.” 
About the middle of July, Mr. Child forwarded me a mass of 
this inflamed tissue, or “jelly,” obtained from the animal whilst in 
the process of dressing, so that the material was taken both from 
the hide and the carcase at the same time, and as warble maggots 
were present in it the specimen was a very perfect example, because 
the cause of the evil (namely, the maggots) were there plainly to be 
seen, as well as the damage they had caused. This mass I 
forwarded, by his kind permission, to Mr. John Penberthy, Pro¬ 
fessor of Pathology at the Royal Veterinary College, Camden Town, 
N.W., requesting him to tell me the nature of the so-called “jelly,” 
and the cause of the diseased condition, to which Prof. Penberthy 
replied:—“I have made an examination of the specimen sent- 
The so-called ‘jelly’ is the product of inflammation, and there is 
every reason for believing that this inflammation is due to the 
warbles. The material is not fit for human consumption. I think 
it very deleterious to the health and comfort of the affected 
animal.” 
On the 19th of July, in reply to my request that he would tell 
me by what name the diseased tissue should be described, Prof. 
Penberthy wrote as follows:—“I should call the material inflam¬ 
matory product in the subcutaneous tissue. Inflammatory product 
is made up of constituents of blood exuded through vessel-walls 
which have been damaged. It is allowed by some pathologists 
that inflammation, too, may excite growth of the cells previously 
existing in the part. The dark red colouring is most likely due to 
escape of blood from small vessels which have ruptured. The 
orange-coloured material, which I have found in some cases, is 
inflammatory product undergoing degenerative changes ; in others, 
decomposing warbles.” 
Another very fine specimen for our purpose was sent me by 
favour of Mr. H. Thompson (before mentioned). This consisted of 
the whole length of spine,—that is the backbone, flesh, skin and 
all, cut right out along the centre of the animal after slaughtering. 
On examination it proved to be only moderately warbled, the 
number of warbles (twenty-six, including the very small ones) not 
being more than are often met with; so that whilst the above- 
mentioned specimen gave example of the completed mischief, this 
one showed the earlier stage of injury from moderate and not fully-
