Amyloid Deposits. 
Amyloid deposit is reported with reasonable frequency 
in domesticated animals, causing in them a fairly definite 
entity, being as usual related to the effects of long con- 
tinued or repeated infectious disease. Wild animals suf- 
fer from this condition but rarely and therefore to our 
few cases will be given a short discussion separately. An 
Indian Paradoxure (Paradoxurus niger) had patches of 
amyloid irregularly distributed through the organ. The 
animal had a carcinoma of the head of the pancreas, an 
obstructive biliary cirrhosis in a state of atrophy and 
a chronic nephritis with arteriosclerosis. There was 
nothing peculiar about the distribution of the deposit as 
there was in the next case, a Badger (Meles meles) where 
amyloid was found around the interlobular vessels and 
extending in the lobules along their canaliculi. This 
latter case seemed without cause and we have considered 
it a primary amyloidosis, the spleen, heart muscle, kid- 
neys, intestines and other structures being affected. ( See 
Fig. 7.) A third mammalian case concerned a Dasyure 
{Dasyurus viverrinus) which showed distinct intralobu- 
lar collections. Its cause was a chronic suppurative 
process in the jaw bone. 
Avian livers are somewhat more prone to show amy- 
loid deposits, eight cases being on record. Four occurred 
in the Passeres, one each in Columbae and Impennes and 
two in Anseres. Three were associated with chronic 
infectious disease and two with well established nematode 
parasitism. The remaining three, classed as primary, 
were not related to any other lesions, in two the amyloid 
liver being the only finding. 
The next abnormal deposition related to the physiology 
of the organ is blood pigmentation. Normally hemic pig- 
ment is dispensed with very rapidly but under unnatural
