of the occipital pole has to be taken in account as von Monakow 
desires, but most probably even more. — 
The retinal projection on the cortex, secondary to that of the 
lateral veniculate body is therefore without doubt much more com- 
plicated than HerscHeN had figured to himself. 
In 1909 I myself) could prove that the geniculo-cortical radiation 
and the geniculate body reacted differently, if by dorsally situated foci the 
dorso-lateral division of the strata sagittaha was cut through, than 
they did, if ventrally situated foci destroyed. the ventro-medial divi- 
sion of these strata in the occipital pole. In the first case, with in- 
complete quadrantic hemianopsia of the lower fields of vision, the 
dorsal division of the radiation and the medial part of the geniculate 
body was greatly, but not altogether degenerated. 
In the second case the degeneration took place in the ventral division 
of the radiation and the cauda of the body. Both degenerations were 
incomplete. At present | can communicate two new cases, this 
time of complete partial atrophy of the lateral geniculate body 
‘cauda or caput), of which one with exquisite quadrantic hemianopsia, 
and through which | am obliged to extend even more than Monakow 
did, the areae of the cortex for the lateral geniculate body.

Nephritis. Attack of unconsciousness on Dec. 9 1910, followed by transi- 
tory sensory aphasia, aleria and permanent quandrantic hemianopsia in the 
lower right fields of vision. which in July 111 is tested through the oph- 
thalmologist. In January 1912 second insult, which causes death. Autopsia: 
Old haemorrhagic cyst in the Gyrus temporalis Il and the Gyrus angularis, 
sectioning completely the dorsal optic radiations. Fresh bleeding immediately 
next to this in the dorsal strata sagittalia. 
Miss U. P. S....., 37 years, is the eldest of 9 children, of which 5 are still 
living. The mother of this family died 50 years old of apoplexy, the father 75 
years old of nephritis. Mentel or nervous diseases did not exist in the family. 
No abusus alcoholieus, no syphilis. Before this present illness she had nothing 
to complain of. 
On the 9! of December 1910, she all at once fell unconscious, remained uncons- 
cious for 10 days. After coming to, she spoke with much difficulty, she could not find 
the words, asked for ‘‘scur’’ (zuur) when she meant “butter milk” (karnemelk), etc. 
She soon regained a certain quantity of words, although she did not understand 
everything allright, but even now (July 1911) she names with difficulty the objects, 
which she recognises well. Especially proper names and nouns she often uses in 
the wrong way. Moreover after the attack she could not read, partially, as she 
says, because she soon grew tired, partially because she did not understand much 
of what she read.
