In the cases of the filberts, peanuts, and Brazil nuts good crystals of man- 
nose hydrazone were obtained from the undiluted, evaporated liquor, though 
it was evident that no very large quantities of mannose were present in the 
products of the hydrolyses. 
Coffee (Coffea Arabica). A mixture of raw ‘‘ Mocha and Java” coffee, 
bought in Boston market. The so called coffee beans of commerce 
are really the seeds of the plant taken from the fleshy fruit or berry. 
These seeds were ground to powder and hydrolyzed in the usual way. 
No difficulty was encountered on testing the unevaporated product of 
the hydrolysis, but on evaporating the reddish liquor to soft dryness
