On decanting this, an oily liquid remained, which on cooling 
became a crystalline mass; and this after purification gave on 
analysis the formula C,H,OSNa a,H,O. To establish the constitu- 
tion of this body, nothing more is necessary than to convert the 
hydrate into the chloride, ~ see if the chloride contains aie yor.

Ont the Bpntheaiin oF Ozxindol.—The conception that ica acid 
is is oxthoumidophenylalyoxalic acid and that isatin is its anhydride, 
as first enunciated by Kekulé in 1869, who announced ~ inten- 
tio n to prepare orthoamidophenylacetic acid, and from this by 
oxidation to produce isatin. Banysr has now succeeded for the 
oxindol. That o: 
dride of orthoamidophenylacetic acid was proved by Suida, who, 
at Baeyer’s suggestion, examined the question whether, in the 
reduction of isatin to oxindol, one or two CO groups were attacked, 
and if only one whether it was that group which was attached to 
the benzene, or the other one. On analytical grounds, the formula 
4 f tay was established for oxindol, thus answering the 
problem. The synthesis of one | is extremely simple. Phenyl- 
acetic acid is nitrated by means of fuming nitric acid, — 
nitrophenylacetic acid. This i is reduced with tin and hy 
nitrous acid.— Ber, Berl. Chem. Ges., xi, 582 Raa 1878. G.F.B.
