stage of the maggot, half-way down the white thick portion 
of the hide. She thinks the first stage of the maggot, 
until it gains its prickly coat, is passed harmlessly in the sub¬ 
cutaneous tissues. Dr. Brauer says the beginning of the cell 
takes place in the sub-cutaneous tissues, to which the minute 
grub has burrowed down, as some think by the hair follicle, 
but this latter point is doubtful. In the United States and 
on the Continent the warble becomes visible on fleshy side of 
hide in the latter part of September. On December 5th, 
two swellings were found on the fleshy side of hide of a 
bullock killed the previous day at Spring Grove, Isle- 
worth. 
The first note of outside swelling was reported by 
Mr. David Byrd, Tarporley, Cheshire, on December 4th, 1884. 
He says :—“ We see many lumps on the backs of cattle, at 
present not large.” In beasts fed at Aberdeen under cover, 
two embryo warbles were found on December 26th, 1884. I 
have examined the backs of several two-year-old bullocks and 
heifers, afflicted with warbles in the spring, during this month 
(December), up to the 21st December, but have been unable 
to find any warble swellings. 
From German observations, about the end of August or 
beginning of September is about the time the warble opens 
on the Continent. One observer considers the warble begins 
to form very soon after the presence of the maggot in the 
hide, and three or four weeks after he has noticed the animal 
trying to get at the spot with its tongue, he has found a little 
lump, and squeezed out the maggot when only the size of a 
Blow Fly’s grub. It appears certain that in this country the 
open warble is not generally seen until from about the 14th to 
the 25th of February. On January 27th, Mr. Dalton, 
Wigton, noticed for the first time in the season the appearance 
of the young warbles. He found them in two different 
hides, both of them from one to two-year-old cattle. The 
round hole in the warble was distinctly visible. It was 
about the size of the prick of a common darning needle 
outside, and below, though larger, scarcely j^th of an inch 
across. 
On February 14th, Mr. McBride, county Cork, stated that 
the swellings were increasing in number and size on his cattle.
