THE CONTAGIOUS DISEASES (ANIMALS) ACT, 1869. 483 
readers supply this deficiency ? They would not only confer 
a personal favour on us, but would assist materially in settling 
some imperfectly known peculiarities in the several varieties 
of the breeze-fly. Warbles on the backs of bullocks are com- 
mon enough, but it is only occasionally that they exist, and 
then to a limited extent, on horses in this country. The 
larva of the ox greatly exceeds in size that of the horse, and 
changes earlier from a white to a brown or black colour. 
Essentially, however, their natural development is the same 
in both animals.
