of this nature, wrote me: “Regarding your query about warbles in 
the horse, I have only known one case.” Mr. R. Stratton, of the 
Duffryn, Newport, Mon., amongst other information with which he 
kindly favoured me about this attack, mentioned: “You seldom 
find more than one on a horse.” Messrs. H. & C. Hatton, of the 
Barton Tannery, Hereford, noted that they had known a few 
instances of horses being attacked by Warble Fly, but had never 
received a hide showing the effects. Mr. John Dalton, also of the 
Tannery, Wigton, Cumberland, mentioned: “ Of the horse-hides I 
get, I should say not one in fifty is warbled, and the appearance of 
the hides when tanned shows that warbles in the horse are of rare 
occurrence ; there is no cicatrix, as in cattle, and when a warble 
does exist, it is a single one, and never, so far as I have seen, in 
numbers ... I never remember seeing more than one warble 
hole in a horse-hide ; I mean in any single hide.” 
The locality of attach was noted as being not only along the 
back, as commonly occurs in the case of warbles on cattle, but 
also on neck, flank, and quarter. Also, though the numbers of 
warbles were very few, both by reason of the very small proportion 
of horses attacked, and also the very small presence on the attacked 
animals, yet the mischief caused was (or had a power of being) 
much more serious than is caused by any one warble in cattle. 
As an example, Mr. Thompson, before referred to, wrote me 
that in the case of a warble under his treatment on the neck of a 
horse, that the swelling caused was diffused and extensive (nearly 
all the length of the shoulder-blade). Points also as to duration 
of the maggot attack, date of opening of the warble, and size of 
orifice, appeared not as well known as in the case of Ox Warble 
attack. 
The above notes refer to communications sent in 1886, and 
since that date no observations worth record have been sent me, 
excepting that in 1894 I had information from a contributor at 
Cardiff, that in the case of a mare which he had bought in the 
previous January, without there being any signs of warbles on 
her, by the middle or end of February there were “ at least forty ” 
distributed on the shoulders, back, and quarters. Of these, such 
as were not squeezed out, were, my informant wrote, treated with 
a mercurial application, which destroyed them all in a week or ten 
days. 
In the above remarks I give the information sent me in the 
course of inquiries, to which I attended to the best of my power 
(although not in the scope of my regular work), and, leaving the
