into the substance of its several organs ; but their presence has 
always been marked with unmistakeable indications of dis- 
ease. Such substances are well known to travel from one part 
to another of the body, after having been accidentally intro- 
duced from without. Mr. Youatt, in his work on cattle, 
gives the following case, on the authority of M. Dupuy, 
Director of the Veterinary School of Toulouse. 
“ A bull, three years old, died after an illness of fourteen 
days. The symptoms scarcely extended beyond the peculiar 
heaving and short cough of hoove. On examination after 
death, it was found that the second stomach adhered to the 
diaphragm by a false membrane, which was clearly the con- 
sequence of intense inflammation of that stomach. The coats 
of the reticulum had been pierced, and in the aperture was a 
piece of iron wire, that had penetrated through the diaphragm 
and the pericardium, and entered the right ventricle of the 
heart. Within the diaphragm, and between it and the heart, 
was a sac containing nearly a pound of blood mingled with 
the liquid food usually contained in the second stomach. 
" The mischief had been of long standing, for the walls of 
the ventricle were become white and of a cartilaginous struc- 
ture, and the ventricle itself was filled with coagulated blood 
deposited layer upon layer. The pericardium was contracted 
and adhered to the heart, and might almost be said to have 
disappeared. The lungs were emphysematous, and contained 
numerous encysted tubercles resembling hydatids, or actually 
being so.”] 
DISEASE AMONG SHEEP. 
We learn that a great fatality is prevailing among the sheep 
in several parts of the country, from the animals becoming 
attacked with acute congestion of the lungs Few pre- 
monitory symptoms have been observed in the major number 
of cases, and in numerous instances death has occurred very 
suddenly. The disease most likely depends on the high 
temperature which now prevails, and we are of opinion that 
the allowance of a small quantity of salt; free access to water, 
and the placing the animals in shady situations, wouli be 
attended with beneficial results.
