SECTION IV. 
The effects produced by extravasated blood. 
Blood in the lateral and third ventricles was attended by 
repeated fits of vomiting and coma.* In the fourth ventricle, 
a fit which in twenty four hours terminated in death ; under 
the anterior lobes of the brain by hiccoyghs and stupor ; J 
under the cerebellum, by convulsions of the neck and body, 
with drawing up of the feet without stupor ; § in the folds 
of the pia mater covering one hemisphere, by a paralytic 
affection of the opposite side, without any other symptom. || 
Blood in the folds of the pia mater over the posterior lobes 
of the brain, and serum in the cornua of both the lateral ven- 
tricles were attended by giddiness, paralysis, straight objects 
appearing crooked, loss of memory, and at last idiotism.^ 
In the right thalamus nervi optici, extending into the lateral 
ventricles, by paralysis of the left side of the body, both eye-lids 
closed, the mouth drawn on one side, a perception of light 
• A coagulum of blood, the size of a common leech, lying upon the plexus 
ehoroides of each lateral ventricle, and two ounces of serum were found in a person 
who had the symptoms stated. 
-}• Half an ounce of blood was found in the fourth ventricle. 
X Three ounces of coagulated blood were found upon the basis of the skull, under 
the anterior lobes. 
§ Blood was found coagulated under the cerebellum. 
II The extravasation was in small quantity. 
^ A person 69 years old had a paralytic stroke, from which he recovered ; but 
had giddiness, and straight lines appeared crooked. He had a second, which termi- 
nated in idiotism which lasted a year and a half ; he then died. It appeared that 
there had been two distinct extravasations of blood in the pia mater, which had com- 
municated with the cornua of the lateral ventricles, in which were deposited six 
ounces of serum.
