and I would submit that for those whose herds are 
usually infested to have them, or some of the cattle 
examined, say once a fortnight from September onwards, 
until the coming warble is felt, would be very desirable. 
Then, when we find the date of the first opening, the 
cure of the attack lies in our own hands. 
During experiments recently tried by Mr. R. Stratton, 
of The Duffryn, on developed warbles, he found that the 
effect of placing a very small quantity of mercurial 
ointment on the opening of the warble not only killed 
the maggot within, but that in a couple of days after it was 
decomposed. This cheap and easy application, or many 
others, would probably act just as well on the young as the 
old maggot; and, if we can get to know generally when 
the pest first lies in our power, we can not only save the 
injury to the health, but the loss on the warbled hide. 
At first there is only a small sore, but after the winter 
we have to deal with a perforated hide and a maggot-cell 
spreading as much as an inch in length in the thin 
tissues beneath the firm part and just above the flesh. 
The real amount of damage cannot be appreciated 
until the portion of infested hide is examined after being 
taken from the animal. Then we can see firstly, in the 
soft under side, a swelling about as large—we may say 
generally—as half a walnut : this is caused by the pres¬ 
sure of the maggot within. On making a clean section 
of this we find an upright perforation through the hide, 
about the eighth of an inch across at the top, gradually 
increasing until, when it has passed through the firm 
parts, it bends in its course, and forms an irregular bag, 
wide enough for the accommodation of the maggot, and, 
as I said just now, about an inch long, in the sub¬ 
cutaneous tissues. In the cell the maggot lies slantwise, 
with its tail-end (containing the breathing apparatus) at 
the orifice above and the head below. In those which 
I examined, though the upper part of the cavity was 
healed over the surfaces, the maggot was still keeping 
up a sore and a flow of ulcerated matter at the further 
extremity by fairly grubbing and sucking at the living
