SEVERITY OF WARBLE-ATTACK. 
15 
a half old, which was very much warbled, and which showed signs of 
a considerable amount of inflammation. I have cut a piece out and 
forward it for your inspection. You will notice that the mem¬ 
brane covering the warble is much thinner than at a later period. I 
cannot help thinking that the death of this animal has been brought 
about solely by warbles: the irritation caused by the presence of so 
large a number must have been very great, and it may be supposed 
the draw upon the system to supply such a large colony with food 
must have been more than could be borne.” — John Dalton, Wigton, 
March 28th, 1885. 
[The thinness alluded to was very noticeable, the segments of the 
maggot being clearly discernible through the membrane. The piece 
of hide contained eight or nine warbles in a space of not more than 
two and a half inches square, and was in a state of inflammation. The 
maggots were upwards of a sixth of their full growth, and the warbles 
containing them in some cases so close together as not to be clearly 
distinguishable from each other.— Ed.] 
“ Almost immediately after receipt of your letter to-day we had the 
skin of a yearling sent in ; it was covered with warbles down the 
centre of the back. The man who brought it said they considered it 
died of ‘blackleg.’ We think the warbles killed it. This makes the 
fifth within the last four or five days, all supposed to die of ‘ blackleg, 
or quarter-evil,’ but all equally affected by warbles. By this post we 
send you a box of the maggots, all of which the writer cut out within 
the space of this sheet of paper.”—Messrs. C. and H. Hatton, Barton 
Tannery, Hereford. 
“We received a hide to-day taken off a beast supposed to have 
died of ‘ blackleg.’ Looking at it spread open, it was most distressing 
to think that a poor beast should be allowed to get in such a state. 
However, we have cut the centre out, and send it you by this post.”— 
Messrs. C. and H. Hatton, Barton Tannery, Hereford. 
[The piece of hide was 28 in. long by 8| in. at the widest part, and 
contained upwards of seventy-two warbles.— Ed.] 
From Mr. W. Williams (tanner), of Haverfordwest, I heard (when 
writing regarding distribution of leaflets):— 
“I should make a point of giving a copy to each farmer when 
paying him for his dead hides, of which great numbers come in every 
spring with their backs in a mass of jelly from warbles. I have some¬ 
times pointed out cases where the warbles were sufficient to cause 
death, but the farmers will not believe it, and say it was inflammation 
of the kidneys.” 
In the course of our investigations, through the courtesy of Prof. 
Worfcley Axe, of the Boyal Veterinary College, Camden Town, who at 
my request examined for me the heart of a runt which was warbled
