A neighbour of ours at Stoke Ferry, about three miles 
distant, where the cattle are much afflicted with this pest, 
rubbed spirits of tar along the animals’ backs about every 
other morning during summer, and he says they were quite 
free from warbles next spring. 
About November 1st, 1884, Messrs. Hatton stated that 
they had recently found lumps about the size of buckshot on 
fleshy side of hide from a yearling. On November 12th, 
they forwarded a piece of hide to Miss Ormerod. It 
measured 12 by 4 inches, and on the flesh side were more 
than seven slight swellings about J inch across, of a livid 
or bluish colour, each forming a raised centre to greatly 
inflamed patches. These were under the sub-cutaneous 
tissues. Within the blue centre Miss Ormerod found a small 
Warble Maggot, just large enough to be distinguished by the 
naked eye when removed, but not plainly so while in the 
swelling, as the inside of this was of blood-red tissue, and the 
maggot was of the same colour. It was plainly distinguished 
under the microscope by its patches of minute prickles. From 
the red mass or inflamed swelling a fine channel was found 
passing through the hide to the surface. While handling the 
specimen, blood was forced up from the swelling through the 
channel, and collected in a little drop on the outside. Within 
these swellings the maggot lay free—that is, not enclosed in a 
cell. The channel appeared to have no lining membrane, but 
to be merely a passage gnawed or torn by the mouth hooks of 
the maggot, and was sometimes slanting, or taking a straight 
course, or so completely curved at the upper part of its course 
that it was not possible for the ovipositor to have caused it 
where the curve existed, proving that the egg is laid either 
outside or just beneath the outer cuticle of hide. In one 
instance, she found the gallery or maggot-run curved back, 
and running just under the cuticle, and ending in a cell (A), as 
in fig. 6. She also found some similar 
small cells without any gallery down, 
and in some of these she found a 
gallery just beginning to be formed 
in one case, and in another, an object 
not as yet in a prickly skin, but Fig. 6.-Curved maggot run.
