Amyloid Disease. 
Last year Dr. Weidman placed on record two cases 
of apparently primary amyloid in birds. This past 
report period has brought out two mammals and a bird, 
a jungle cat (No. 5212), a skunk (No. 5414) and a 
chestnut-eared finch (No. 5221), with a similar condition. 
In the first the spleen was involved, in the second the 
kidney and in the last the liver. Four other instances 
of amyloid deposit were found but these all have some 
other lesion to account for it, tuberculosis or long standing 
inflammation. 
LiTHIASIS. 
Four instances of calculus or concrement formations 
were encountered. They do not permit generalizations 
so that only a few brief observations are reported. In 
the leopard tortoise (No. 5306) very numerous intrarenal 
stones were found, ranging in size from granules to 1 cm. 
They lay deeply and firmly imbedded in the cortices and 
medullse and seem surrounded by a moderate amount 
of connective tissue. No pyelitis existed. 
The Barasingha deer (No. 5423) showed two stones in 
the left renal pelvis, one an irregular dark uric acid 
stone molded to the calicos, the other triangular and free 
but lying over the opening of the ureter when the pelvis 
was opened. The pelvis is little if any damaged. 
Twenty-six hard dark stones were found in the gall 
bladder of a brant goose (No. 5128), one of which was 
impacted in the opening of the gall duct. There was a 
mild hypertrophic cholecystitis. 
Coproliths occurred in the ileum and ceca of a brown 
pelican (No. 5494). They were well molded to the 
intestinal lumen but movable enough to let something 
pass. They seem to consist largely of urates but some 
dark irregular matter was also present. 
Arteriosclerosis. 
No progress has been made beyond that reported in 
the paper read before the College of Physicians, to appear
