TUMOUR lx\ THE BRAIN OF A HORSE. 
large quantity — more than a handful — contained in a 
cyst at the bottom of the orbit. These proved to be 
hydatids, and, I believe, of the variety designated llydatls 
endogena. The entozoa varied in size from that of a pea to a 
small marble, but how they, or the ova from which they were 
produced, found their way to the locality in which they were 
found I shall not venture an opinion upon. 
The case is unusually interesting; I have never seen or read 
of one similar to it. Others, however, may have done so; 
but they have not, that I am aware, recorded the fact. 
I hope that the members of the profession will continue 
to contribute cases of interest which may come under their 
notice, for if they will only do this such an amount of 
information will be accumulated which cannot prove other¬ 
wise than a valuable addition to veterinary literature. 
CASE OF TUMOUR IN THE BRAIN OF A HORSE. 
By W. P. Toll, M.R.C.V.S., Lichfield. 
I little thought, when sending the report of a case of 
tumour in the brain of a horse in October last, that it would 
so soon fall to my lot to transmit you another so much 
like it as the present, both in symptoms and morbid 
appearances. 
The subject of this report was a bay carriage-mare, thirteen 
years old, in good condition, the property of a market 
gardener in this place, which he used chiefly for the purpose 
of working his land and taking the produce to market. 
September .SOth, 8 p.m.—The mare was reported to me 
as being attacked with colic soon after she returned from her 
work. On arriving at the stable I found her rather uneasy, 
stamping and scraping the ground with her fore feet, and 
occasionally turning round in the box; she did not, however, 
lie down. The pulse was soft and regular, and about forty 
in the minute. The extremities were warm, but nothing 
had been seen to have passed from the bowels all the 
afternoon. 
Considering the pain to arise from indigestion, I gave the 
following draught:
