The firft of thefe is a fpecies of dropfy, incident 
to bullocks and fheep. In opening thefe animals, 
when dead of this rot, the liver is always found af- 
fected. A fmall flat worm, refembling a foie (and 
often many of them), is found in the gall-duCt, by 
the butchers term’d flqoks. It is the property of 
this worm, that it always builds a wall of ftone for 
its defence j which wall is ramified like the gall- 
duCt, within which it is formed. This ftony tube 
(when completed) blocks up the gall-duCt, and flops 
the paflage of the gall ; which thereby furcharging, 
the duCt, and dilating the orifices of the lymphatics, 
returns again into the blood, and gives the yellow 
teint to the eyes, which is the fiifl fymptom of this- 
difeafe, and generally precedes the lofs of flefh, and’ 
the fwelling of the belly . It feems probable, that what- 
ever can increafe the acrimony of the bile, muft be 
ufeful in preventing this difeafe ; but when the 
ftony pipe is form’d, no method feems capable of 
promoting its difeharge, or diffolution. 
The other cafe is termed the hufk, and is a dif- 
eafe, to which bullocks are very fubjeCl, while young ; 
for it rarely affefls thofe of more than a year old. 
The creature is feized with a fhort dry cough, by • 
which he is perpetually teized; in confequence of 
which he waftes in flefh, and grows weaker and 
weaker till he dies. 
Upon opening the lungs of acalf deadof thisdiftem- 
per, I found the windpipe, and its branches, loaded 
with fmall taper worms of about two inches long, 
which were crawling about, though the animal had
