3. On the production of Tartronie from Pyruvic acid.—Gri- 
solved in two or three times its weight of water, and barium 
poh gradually added, the temperature being kept at 30° to 
0° white precipitate soon formed, which, decomposed by sul- 
aie ce acid, yielded a crystallized acid, very soluble in water and 
alcohol, fusing about 142°, and yielding the above formula on 
analysis. The author thinks that the mesoxalic aldehyde-acid 
CHO—CO— COOH is first formed, but that this body being at 
the same time an aldehyde and an acetone, is oxidized on its alde- 
hydic side and reduced on its acetonic. Hence it is hydrated and 
gives COOH —CHOH—COOK, which is tartronic acid. The reac-

4. Ona Hexyl Chloral,—Prsn er has subjected to a more care- 
ful examination an oily body “ high boiling point, first observed 
by him nearly two years ago n the distillation of crude butyl 
chloral. From a kilogram of this oil from the factory of ce 20 
yields trichloreapronic wn C,H,Cl,0,. Reducing agents, such 
as zinc powder, reduc this ‘acid to hexylenic acid C,H, 
which crystallizes etn ether in brilliant white needles, fases at 
39°, is almost insoluble in water, and does not appear to be iden- 
tical with any of the three known acids having the no oma 
cal formula.— Ber. Berl. Chem. Ges., x, 1052, +h
