amount of detail, requisite to guard against every imaginable point 
of inattention to advice. In the above extracts the italics are in 
part additions of my own, to draw attention to the objectionable 
character of some kinds of treatment (as stabbing the grub, or 
stabbing at it) in the warble, and various other points which may 
serviceably be noticed. Only one instance has ever been reported 
to me of ill effects, and in this case the ointment was not applied 
according to directions, but the animal, which was suffering to a 
quite unusual extent from warbles, was smeared along from head 
to tail. Details, comments, and opinions thereon will be found in 
the ‘ Agricultural Gazette,’ Nos. 598, 599, and 601 (1885). 
To the above I venture to add some parts of a letter from 
Dr. Geo. Fleming, Veterinary Adviser to the Army, which he was 
good enough to write me on my laying the details of the case, 
alluded to in the accompanying note, before him, and which he 
also permitted me to give in the ‘ Agricultural Gazette,’ in reply to 
observations on the case :— 
“ With regard to the cases of supposed poisoning of cattle in 
Cornwall, I cannot understand how such an accident could happen, 
unless your instructions were ignored, and the animals were smeared 
and rubbed with a large quantity of the ointment. . . . You 
recommend destroying the maggot of the Warble Fly by just touching 
it with a little mercurial ointment, such as is used for scab in sheep." . . . 
Dr. Fleming went into all points seriatim of the illness and death 
of the animal, which was ascribed to treatment with mercurial 
ointment, giving details as to amount and effects of action of 
mercurial ointment, all which will be found in ‘ Agricultural 
Gazette ’ as referred to, and ended the long consideration he was 
good enough to place in my hands with this sentence :—“ I am 
confident than no ill effects can arise if your directions are followed 
with anything like ordinary care.”—G. Fleming, LL.D., F.R.C.V.S. 
Where cattle are suffering badly from warbles, so that the health 
is clearly affected, and the animal wasting, the use of the well- 
known old “ black oils ” has been found to do much good. 
Mr. Henry Thompson, of Aspatria, frequently quoted before, 
gives the following recipe used for a bad case:— 
“Last year about this time I was called in to a little three- 
year-old heifer whose back was almost covered with warbles, and 
the effect on the constitution was very marked; the poor thing 
was very thin, and would not eat. I was satisfied that the 
irritation set up by the warbles was the cause, and applied the 
following:—Turpentine, 1^ oz. ; sulphuric acid, 1 drachm (here a
