On February 17th, information was sent that a notice had 
already been given that hides on Birmingham market would 
be sorted for warbles, and those having more than three 
would be out-classed. On February 18th, Messrs. Hatton 
mentioned that they had received an ox hide with many 
warbles in it. The value of this hide was 29s.; whereas the 
value of the same weight of hide free from warbles would 
have been 35s. 5d. The amount of damage can be seen on 
looking at the under side of an infested hide. The swellings 
there are about the size of half a walnut, caused by the 
pressure of the maggot within. On February 20th, Miss 
Ormerod found an open warble in the hide of a Hereford, 
taken from the animal that day at Isleworth. On February 
23rd, Mr. Scott, Tipperary, found warbles on cattle. On 
February 24th, Mr. H. Thompson, Aspatria, reported that he 
had found several small lumps on the backs of young cattle, 
but no external opening ; and on the same day, some of the 
students of the School of Agriculture, Aspatria, found lumps 
on the backs of cattle at the farm ; and another reported 
small lumps on the backs of his father’s cattle, with black 
spots in the centre, covered with gummy matter. On February 
25th, Mr. H. Thompson found a large number of warbles on 
the backs of cattle rising two years old. Some of the cattle 
had twenty swellings on the back, all showing the external 
opening. 
Those specimens found by Mr. Dalton, and examined by 
Miss Ormerod, presented the first advance on the condition of 
a hair-like streak through the hide. These were the first per¬ 
forated warbles found, the maggot within being of a clearly 
distinguishable size. The channel or maggot gallery was 
somewhat cone-shaped, with smooth, white, shiny walls. This 
shows that the passage could not have been formed by ulcera¬ 
tion, which would not have given clean smooth walls to the 
hole. The maggots in this state of warble differed in size. 
The smallest she measured was about \ inch long, and nearly 
worm-like in shape, rounded at the mouth end, and bluntly- 
pointed at the tail; white, transparent, and marked across 
what may be called its back with sixteen short bands of very 
minute black or dark-grey prickles, placed for the most part 
in alternate very narrow and broader stripes. The maggots
