TEST FOR GRAPE SUGAR. 
Professor Bottger states, that when a liquid contain- 
ing grape sugar is mixed with carbonate of soda and some 
basic nitrate of bismuth, and then boiled, the presence of 
sugar, even in very minute quantity, is indicated by the 
grey coloration or blackening of the suspended bismuth salt, 
which is reduced either to suboxide or to metal. He states, 
also, that none of the other constituents of urine give rise 
to this reduction, and consequently recommends this test as 
preferable to Trommer’s test for the examination of urine. 
Cane sugar does not produce reduction of the bismuth salt 
like grape sugar, so that the presence of grape sugar mixed 
with cane sugar may be detected by this test. — Pharmaceuti-
