The platinum salt of glycosin contains, according to Horsford’s 
analysis, 83-2 per cent of platinum, and he considers it to be 
CsH1NOs. PCl2, ; 
which requires that percentage. But Cahours* assigns to this : 
salt the formula a 
OsHsNO1.HC1+-PCh, 
which, upon the view which I have proposed, becomes

The other salts of glycosin are easily formulated upon the am 
monium theory, and do not require special notice. The combi 
nations which glycosin forms with metallic oxyds are however — 
of no small interest from the point of view suggested. Thus — 
Boussingault found for the compound with oxyd of silver the
