Prevention and Remedies. —Tlie maggots of Gastrophilus equi, 
as well as those of other species of the Gastropliili, “ are found in 
horses which frequent pastures, or live much in the open air, and 
which do not receive much grooming. The age, state of health, or 
disease, and mode of feeding have no influence on them.”—(W. F.) 
Regular methods of treatment are, such combings, brushings, 
clipping away hair from infested parts, as would get rid of a deal 
of infestation, and the use of such soaps and washes as, whilst 
they would not be in any way injurious to the horse, would help to 
get rid of hatching maggots, and to some degree of eggs, though 
the firm hold of these to the hair makes it very difficult to dislodge 
them. 
Washes, or smearings of any kind of insect deterrent, such, for 
instance, as paraffin oil, as used to keep off Horse Forest Fly, would 
almost certainly help to prevent egg-laying if applied from time to 
time to the parts preferred for oviposition by the flies. 
As it is stated that the flies do not follow the horses into 
stables, it might be worth while to allow horses access to stables 
or field sheds in hot weather, or when horses showed from the 
egg-presence on the hair that much attack was going on. 
One very obvious and certain way of lessening recurrence of the 
infestation is to notice whether there is presence of the yellowish 
or yellowish pink maggots, or the brown or blackish chrysalids, in 
the horse droppings, and to take requisite measures to destroy 
them, probably by throwing on some strong dressing, but in some 
way treating the filth so as to render it harmless. If buried, it 
should be buried to a good depth, as otherwise (it being natural to 
the maggots to bury themselves) in all probability the flies on 
developing from the chrysalids will, according to their usual habits, 
simply come up to the surface and take wing, as if nothing had 
been done. 
In regard to remedial measures, this lies in the province of the 
Veterinary Surgeon, but in a communication with which I was 
favoured by Mr. Hy. Thompson, M.R.C.V.S., of Aspatria, Cumber¬ 
land, he mentioned: “ I know of no medicine that will destroy them, 
or make them leave their winter quarters until fully developed; ” . . 
but if it was thought desirable to try some remedy in the way of 
medicine, he mentioned that he considered “two oz. turpentine 
and twenty oz. of raw linseed oil, mixed, and given as a draught 
once a fortnight,” to be the best. 
In the work quoted below it is mentioned that “From all the 
serious attempts made before him and by him, and numerous
