SECTION VII. 
The effects of pressure from Tumours. 
An hydatid imbedded in the substance of the right hemi- 
sphere of the brain, was attended with violent head-aches, and 
•occasional fits similar to those of apoplexy.* 
A tumour in the substance of the posterior lobe of the brain, 
was attended with derangement of the functions of the stomach 
and bowels, double vision, and afterwards loss of sight.-f 
A tumour pressing on the left hemisphere ; settled melan- 
choly, drowsiness after dinner, requiring being carried into the 
air, which took it off', buf it returned on coming back to the 
table. A tumour in the fourth ventricle, epileptic fits, sore- 
ness in the throat, and great pain in the act of deglutition. § 
A tumour in the tuberculum annulare and water in the ven- 
tricles, pain in the head, stumbling in walking, the mouth 
drawn on one side, loss of sight of one eye, although the pupils 
were not affected ; dullness in hearing, difficulty of swallow- 
ingjSo as to die starved, with all the mental faculties entire. || 
* It was the size of an orange, had firm coats in which was contained a limpid 
fluid in the quantity of four ounces. The sides of the lateral ventricles were closely 
pressed together. 
f The tumour was of the steatomatous kind just above the tentorium, of the size 
of a turkey’s egg, so as to raise up the posterior part of the lateral ventricle. The 
complaint, till just before death, was mistaken for worms. 
J The tumour was of a soft nature, the size of a filbert, attached to the left side of . 
the falx of the dura mater, a little above the tentorium, pressing upon the left hemi* 
sphere of the brain. 
§ The tumour was of a soft steatomatous structure, the size of a walnut, but 
adapted in its shape to the form of the ventricle. 
II The tumour was of the size of a walnut, composed of a suety matter, four ounces 
of water were found in the ventricles, and the tunica arachnoides was unusually dry.
