400 SANDY SOIL IN DISEASED COLON AND C^CUM. 
2Sth Day .—The wound is now contracted to one-third of its ori¬ 
ginal dimensions. In another week (making altogether five weeks 
from the period of the operation), I imagine it would be healed: I 
make this remark, because the animal will to-morrow, or next day, 
be destroyed. 
ZOtk Day .—This morning the poor old horse was dispatched. The 
wound is nearly closed : it still discharged abundance of pus, but 
no saliva has been seen for some time. The thickening of the 
surrounding parts has of late very much subsided. His viscera 
(at the age of 27), not excepting his lungs, were all found in a per¬ 
fectly sound condition. 
SANDY SOIL IN DISEASED COLON AND C^CUM, 
AND DOTS IN THE OESOPHAGUS. 
By Mr. W. a. Cartwright, of Whitchurch. 
ON the 24th of February, 1.827, I saw a mare belonging to jVIr. 
Jones. She had brought a colt last year, and was in good condi¬ 
tion all the summer; but towards the end of September she was 
removed to land of a wet marshy nature, and continued there 
until nearly Christmas, when she returned to her present pasture, 
which is tolerably dry. She has lately been rapidly losing flesh 
and strength, but no medical attention has been paid to her. 
Symptoms .—Dung very loose, and containing a few small 
worms. She can rise on her fore extremities, but has completely 
lost the use of her hinder ones. She is hidebound, and worn 
down to a mere skeleton. Recommended that she should be de¬ 
stroyed. 
Examination .—colon and caecum contained a quantity of 
liquid faeces, composed principally of soil of a dark colour and 
gritty nature; and the membrane lining them was of a bluish- 
black colour, tender, arid almost rotten. The muscular coat was 
also of a dark colour. In the ileum, just before entering the 
caecum, there were many flukes, resembling those which are found 
in sheep infected with the rot. There were in the stomach about 
forty red bots, of a large size; and in some places they had nearly 
penetrated through all the coats. In the oesophagus, three or four 
inches above the stomach, there were nearly 200 large white 
bots, firmly attached to the cuticular coat: in several places they 
had eaten under that coat, so as to half cover themselves. The 
greater part of the cuticular coat on which they w ere situated was 
of a dark colour, pulpy, and stunk veiy much. These bots must 
have nearly obstructed and filled up the cavity of the oesophagus.
