with sublimated sulphur. The roots were then put 
in sand in the root cellar to be tested as to rot re- 
sistance. 
The quantity of pulp was rather small, however, 
— only about 10 gr. — and therefore the extraction was 
made in a graduated cylinder with a capacity of only 
100 c.c. The analysis follwed for the rest the same 
course, as described in the above with regard to the 
average proofs.
