rigid, and the mare evidently exhibited symptoms of ap- 
proaching tetanus. A cathartic was administered ; the head 
and jaws were stimulated, and the Extract of Belladonna 
given several times during the day. The next morning the 
jaws were completely locked, and the muscles of the extre- 
mities rigid. All the remedies usually resorted to were tried, 
but without effect, and at the end of the fifth day the animal 
expired. 
Anxious to discover, if possible, the cause of the attack, a 
post mortem examination was instituted ; when, to our sur- 
prise, on examining the mouth, a nail, with a head the size of 
a pea, and about a quarter of an inch in length, was found 
firmly stuck into the middle of one of the central incisor 
teeth; and this had evidently been the cause of this sad 
disease. Perhaps this case may be deemed unworthy of 
notice by some, yet it possibly may lead practitioners to look 
more closely into causes, and thus be not unproductive of 
benefit. 
CASE OF HYDATID IN THE BRAIN OF A MARE; 
ALSO OF FALSE PRESENTATION IN A MARE. 
By A. Morgan, Y.S., Dalston. 
Gentlemen, — I beg leave to forward you two cases that 
have occurred in my practice very lately. 
Case 1. — On Monday, May 6th, I was sent for to 
attend an aged mare, the property of a Mr. Church, cab-pro- 
prietor, Hoxton ; which, according to his statement, was 
suffering from spasmodic colic. However, on my arrival, I 
found her standing with her eyes partially closed, and in a 
state of coma. I directly stated to the owner that she was 
suffering from congestion of the brain, commonly called 
“ sleepy staggers.” I administered an aperient draught, and 
gave her an enema of warm salt and water, left her, and said I 
would see her again in about two hours, at the same time telling 
the man to keep cloths dipped in cold water applied to her 
head. On my second arrival, I was about to administer an- 
other draught, when she became very violent and pretty 
soon cleared the stable. After a little time we secured her, 
and I managed to take about four quarts of blood from her, 
as the owner seemed very desirous to have her bled. I told 
him she was now suffering from phrenitis, commonly called 
“ mad staggers and that there was not the slightest hope of 
her recovery. She died during the night. Next morning I
