discoverer of inosite, mentions its breaking up by fermentation 
into lactic acid. Vout, the discoverer of | * rsesohaianiele which 
he subsequently proved to be identical with inosite, also prov 
the identity of the tactic ace from this substance, with the ordi- 
nary lactic acid of fermentation. This statement having been 
called in question by Hilger, Vohl fermented 250 grams inosite 
dissolved in two liters of water, by the aid of esi pp with 
the addition of chalk, at a temperature of 25° The 
thick mass of calcium lactate was treated with cited charcoal, 
boiled and filtered hot. On cooling, calcium lactate crystallized 
out and was purified by repeated crystallization. These — 
had 29-098 per cent crystal water; the salt of common lactic acl 
contains 29°221, that of sarcolactic acid 21°721. The zin 
gave 187104 per cent water, the quantities of the two salts ‘i 
spectively being 18°178 and 12°901. Moreover, the insoluble
