HOKSE WAEBLE.

The other two warbles were in the same animal,—one on the ribs, one 
on the quarter. About this time last year both places were very much 
swollen.” 
On the 27th of April Mr. Thompson mentioned that another 
warble maggot had been taken (also out of the neck) from the same 
horse; and on the 14th of May Mr. Thompson wrote regarding 
another maggot, which had been forwarded :—“ This is the third from 
the same animal, which is very peculiar, as you seldom see them. 
The extensive diffused swelling and effusion they cause in the locality 
attacked is something very remarkable ; not so in cattle.”* 
Messrs. C. and H. Hatton, of the Barton Tannery, Hereford, 
favoured me with information that they had known a few cases of 
horses being attacked by Warble Fly, but had never received a hide 
showing the effects. 
On June 4th Mr. W. Fream, Professor of Zoology at the College 
of Agriculture, Downton, wrote me as follows:—“ Kegarding your 
query about warbles in the horse, I have only known one case. It 
occurred in a farm-horse here about six weeks ago. I was making 
inquiries, and learnt that the grub had been squeezed out only on the 
previous day.” 
On Oct. 9th Mr. A. 0. C. Martyn, student at the Eoyal Agricultural 
College, Cirencester, and writing from thence, mentioned that the 
attack was very rare in that neighbourhood, as he had only found one 
instance, although he had been to almost every farm within six miles 
of the College. In this case one warble had been observed, and 
the maggot squeezed out, and no more information was procurable 
about it. 
In Cornwall, however, during the past year, Mr. Martyn had 
observed two well-marked instances of attack. The first was in the 
case of a colt, which he noticed in a field, under a hedge, flicking his 
tail and trying to bite at something on its back. On being caught and 
examined the animal was found to have three large swellings on its 
back, from two of which Mr. Martyn took the maggots. The second 
instance was of a cart-horse, which had three or four warbles on its 
back, these so far advanced that the air-pores at the end of the tail 
were visible, lying, as with the Ox Warble maggots, in the opening of 
the warble. 
* This third maggot had been forwarded to me in Mr. Thompson's absence, 
and, though still in the cylindrical or worm-like stage, differed from that above 
described in not having any prickles^ excepting a few much scattered at the tail 
extremity, and possibly, but not certainly, a few at the mouth end. The caudal 
breathing-pores were still very small, and the form of the mouth-hooks not clearly 
discernible. This maggot was so very different in amount of prickles to that 
forwarded to me by Mr. Thompson that I cannot take on myself to form an 
opinion of the species.
