recommends anointing the eyes with a mixture of lard 9 parts and

Life history of the worm. Very little is known of the life his- 
tory of the parasite. It seems probable that the embryos pass a 
portion of their existence either free or in a secondary host. The 
reports of the presence of the worm in chickens are, so far as known, 
limited to sea coast regions. This suggests the possibility that some 
conditions peculiar to the sea coast are necessary to the development 
of the parasite. 
. LEECHES IN THE EYE 
One incomplete report exists of the occurrence of leeches in the 
eyes of geese in Ireland. Intense irritation of the eye occurred, 
with symptoms of severe pain. The birds had access to a pond 
teeming with leeches. 
MITES PARASITIC IN CONNECTIVE TISSUE 
Laminosioptes cysticola, accord- 
ing to Neumann, is a mite occur- 
ring in gallinaceous birds such as 
fowls, pheasants and turkeys. The 
parasites live on the surface and 
in the thickness of the skin caus- 
, ing the formation of scurf. They 
are encountered rarely except in 
the subcutaneous tissue especially 
in the places where it is very loose, 
such as the flanks, the vent, on the 
thighs, the breast and the neck. 
They are able to penetrate the deep 
connective tissue. Microscopic ex- 
amination of fragments of subcu- 
taneous connective tissue permits
