The column headed 4 contains the values of 9 calculated accord- 
ing to formula (7) from the individual measurements. 
From these measurements the conclusion can be drawn, that in 
the temperature range from 15 to 22° K. the specific heat of copper 
follows Drsue’s 71° law within 2 °/, 5. 
Anatomy. — “A case of occlusion of the arteria cerebelli posterior 
inferior.” By Prof.:C. WINKLER. 
(Communicated in the meeting of November 28, 1914). 
J. P., aged 58, artisan-painter, has never before shown any other irregularities 
but palpitations after physical exertion before the beginning of his illness on 
October 20% 1912. 
At the age of twelve he became an apprentice-painter, and always afterwards 
kept to this handicraft. As a young man he used to smoke much, and also drank 
much beer, but he firmly denies any sort of veneric infection, though he under- 
went a treatment for strictura urethrae at the age of 45 His father died of con- 
sumption, his mother of jaundice. The eldest sister died of apoplexy. The patient 
is the sixth among nine children. He married young and has five healthy children. 
At eight o'clock in the morning of the 20™ October he suddenly complained 
of dizziness and was obliged to sit down on a chair. He did not lose consci- 
ousness, but could no longer walk because his right leg had become lax. He 
could neither speak nor swallow, and suffered of double vision. 
Before the beginning of this attack he had walked for a quarter of an hour 
over hilly ground, and for the rest had even kept himself unusually quiet. 
For this attack of vertigo he was treated in the hospital at Pretoria. After a 
fortnight he was again able to speak in so far as to make himself intel- 
ligible, although he never completely recovered his voice; swallowing too was 
performed normally again at this time. 
After two months he began to walk about again wilh the aid of a stick. Since 
the attack however lis sense of taste had suffered much After three months the 
double vision had disappeared too. 
He did not suffer from headache either before or during the attack of vertigo. 
Neither had there been any vomiting, nor singultus. 
it left however some lasting symptoms, to wit: 
1. formications (needle-prickings) in the right half of the body and in the left 
half of the face. 
2, his right eye seemed to him to be covered by a film. 
3. he (is) was unable to distinguish between cold and heat with his right hand. 
1) Later, more accurate measurements, which however have not yet been com- 
pletely finished, seem to show that in this region a small deviation from the 
T3-law exists which slightly surpasses the amount mentioned above. [Added in
