diseased parts. The disease appeared suddenly after the removal of 
a ram from one lot of ewes to another, but inquiry failed to reveal 
the cause of the outbreak. No further cases occurred after the 
affected animals were removed from the flock. 
Cattle, Sheep, and Swine admitted to the Royal Veterinary College 
for treatment in 1891. 
During the year thirty-eight animals, including cows, calves,

QUARTERLY REPORT OF THE CHEMICAL 
COMMITTEE, 
March 1892. 
Several cases have occurred lately in which cotton-cake (both 
decorticated and undecorticated) has been found to contain a 
large amount of cotton-wool which has not been removed fi’om the 
seed. 
In one case, not here given in detail, three or four sheep were 
believed to have been killed by the use of such cake, and the 
vendors allowed a deduction of 20s. per ton in consequence. They 
stated, in justification, that they had received a very good analysis 
of the cake. 
It should be pointed out, however, that the figures of an analysis, 
by themselves, cannot indicate the presence of an objectionable 
material of this kind ; also that such a cake, though it cannot, in 
one sense, be called “impure” (inasmuch as it may be composed 
wholly of material derived from the cotton plant), may, neverthe- 
less, be a dangerous one to use for feeding purposes. 
The attention of Members is therefore specially called to this 
point, and they are advised in their purchases to stipulate that a 
cake shall be “ pure and in good condition for feeding purposes.” 
If a cake be passed through a corn-mill and subsequently sieved, 
the purchaser can see for himself the amount of cotton- wool con- 
tained.

December 5, 1891, a sample of cotton-cake with the following 
letter : —
