intense congestion, over the surface of the body, underneath the 
muscles, and, in short, throughout the organism : the weight of the 
heart was exactly seven pounds three ounces. 
Muscular System.-— The muscles of animal life were firm in 
every respect; but, instead of their natural red colour, they ex¬ 
hibited a peculiar yellow tinge, as though they had been steeped 
in bile for some time. 
Nervous System. —The vessels of the brain and spinal cord 
were enormously congested ; serum was effused at the base of the 
brain ; the substance of the brain was firm, and the colour good : 
the same with respect to the spinal cord. 
Urinary Organs.— The kidneys, ureters, bladder, &c. were per¬ 
fectly normal. 
Case III. 
Concussion of the Brain. 
April 12, 1846.—Was requested to attend upon a pony, the 
property of a gentleman residing in this town. 
History, §c. —The animal is a mare ; eight years of age ; of a 
bright bay colour; stands thirteen hands three inches high ; is 
nearly thorough-bred; is remarkable for her speed and great en¬ 
durance ; she has been in the hand« of her present owner about 
two years and five months, during which period she has not been 
affected in any way with disease. Her history prior to the last 
two years and five months I cannot learn; but from her general 
appearance, I have no doubt, she must have been from the 
first a very healthy animal. Her labour is not regularly severe ; 
she is kept for saddle and harness purposes, and sometimes she is 
hunted. 
This morning the owner lent her to a friend of his, who rode her 
to Halifax, a distance of seven miles from this town, which place 
he again left for home at a late hour in the evening, in a state 
which he (the rider) himself describes as being “ something the 
worse for drink.” When he had arrived within a mile of the 
town, the pony either bolted with him, or he flogged her into a 
furious gallop, and, while she maintained that speed, both she and 
the rider were rather unceremoniously intercepted by coming in 
collision with a toll-gate. Other particulars I learned, to the effect 
that the middle bar of the gate was smashed into pieces with the 
animal’s head; that the rider was pitched forward with such 
violence as for a time to cause insensibility to himself; that, on 
recovering, he made many singular observations with respect to 
astronomical science ; he saw several moons, and an incredible 
number of double stars; also beheld a great many ponies engaged
