is often of such a mere film, that the shape and segments of the 
maggot may be clearly seen. 
Piece of under side of warbled hide ; warbles about half size. From a photo^by 
Messrs. Byrne, Richmond, Surrey. 
It is just below the under surface of the hide that the maggot 
carries on its operations,* at first (as previously noticed, pp. 43, 45) 
in the little bloody sore which it has torn in its earliest life, and 
afterwards in the chamber (as figured at p. 48, extended when 
removed from the hide), where it rests with its feeding-end, which 
cannot be called a head, drawing in the foul matter caused by its 
own irritating presence. 
When the maggot has gained the condition mentioned above, it 
is of the shape figured at p. 39, and magnified about four times at 
p. 48, and is from rather more than one line less, to rather more 
than one line more, than an inch in length, and it undergoes no

Parasitic Disease’ (previously referred to), p. 54:—“Larval existence is passed 
beneath the skin of the host, in the subcutaneous connective tissue, in the 
panniculus-carnosus muscle, or underneath aponeuroses. In the earlier period 
no irritation is remarked around the parasites; but when spring arrives, the 
presence of the larva is made manifest externally by tumours.”—(L. G. N.
