on the Functions of the Brain, ^75 
When the water, instead of being contained in the general 
cavities of the lateral ventricles, is principally confined to their 
posterior and anterior cornua, the effects sometimes are 
occasional constipation, pain in the bowels, and lower part of 
the belly. When accumulated in the third ventricle without 
any increase in the lateral ones, distressing pain in the head, 
loss of speech, and insensibility have occurred. -f- When ac- 
cumulated in the ventricles of the brain, and also under the 
tuberculum annulare, painful sensations in the stomach, bowels, 
lower belly, and across the’ legs have been' met with. J When 
not only in the ventricles, but between the tunica arach- 
noides and pia mater over the hemispheres, and also upon 
the tubercula quadrigemina, the apparent consequences in one 
age of 10. A stupor of 12 days preceded death. Four ounces at 1 1 years were followed 
by the sensation of the head being too big, loss of speech, insensibility, convulsions. 
Eight ounces at 74 years were accompanied by a state of idiotism for ten days, and 
then death. 
* Five ounces of water contained principally in four small cells, two in the ante- 
rior and two in the posterior cornua of the lateral ventricles, at 6 years of age, were 
the only evident cause of pain in the lower part of the belly, occasional constipation, 
and violent pain in the bowels. 
4 Two ounces of water in the third ventricle, enlarged by the layers of the septum 
lucidum being separated, at 30 years of age, appeared to produce distressing pain in 
the head, loss of speech, and insensibility. Two drams of water in the third ventricle 
of an aged dog, were attended for four years by fits like apoplexy, pain in the head 
only relieved by opium, convulsions, and death. 
J Two ounces of water in the lateral ventricles, if ounce under the tuberculum 
annulare between the tunica arachnoides and pia mater, at 5 years of age, were 
followed by painful sensations in the lower belly, stomach, and bowels. 
Two ounces of water in the ventricles one under the tuberculum annulare, at three 
years appeared to produce not only painful sensations in the lower belly, stomach, 
and bowels, but pain in the head and pain across the legs, as if they were cut with ao 
instrument.
