56 BULLETIN OF THE BUSSEY. INSTITUTION. 
CO. Specimen chosen on April 18, 1908. The apples were sound 
and in fairly good condition, though much more mellow than 
those selected on February 15. .From the commercial point of 
view they were still in passable condition, though it would not 
have been prudent to try to keep them any longer. 
Flesh of the Banana (Musa sapientum). The yellow variety. Bought in 
Boston market May 29, 1903. The skin was not examined. 
The fleshy part of pickled olives (Olea Europea), bought in Boston market. 
After having been cut into thin slices, the flesh was dried and ground 
to a soft, somewhat pasty mass which was hydrolyzed with hydrochloric 
acid of 5 per cent. in the usual way. 
According to the encyclopedias, pickled olives are the unripe fruit of a 
subvariety called O. oblonga by Duhamel. After soaking in water that con-- 
tains some potash and lime, to remove bitterness, the fruit is bottled in salt 
and water with or without the addition of some aromatic substance. _ 
The saline, slightly acid liquor, poured out from the bottle in which the 
olives had been preserved, was tested for mannose with the result that no 
reaction was obtained from the unevaporated liquor, while good crystals of 
mannose-hydrazone were obtained on evaporating the liquor to soft dryness, 
treating the residue with 10 cc. of water and adding phenylhydrazin acetate 
to three several fractions of this solution, one of 1 cc., one of 3 ec., and one 
of 6 cc. concentrated to 8cc. Crystals of mannose-hydrazone appeared in 
each instance.
