-M. Crozz (Compt. Rendus, March 8th, 1847) has described a sul- 
pho-phosphovinic acid formed by the action of alcohol with the chloro- 
sulphuret of phosphorus of Serullas; it corresponds to the ordinary 
phosphovinic acid, and is represented by PO, S,, C, H, O,2HO or in 
Gerhardt’s notation, representing alcohol C, H, O—H, by E, PO,S 
2 E). By using alcoholic solutions of potash and soda, definite 
crystalline salts are obtained analogous to the phosphovinates ; the pot- 
salt is PO, S(K, E). Wood-spirit yields in the same manner 
sulpho-phosphomethylates. 
hen the perchlorid of phosphorus is placed in an imperfectly 
closed flask containing a small tube of water, it is gradually changed 
into a liquid disengaging at the same time hydrochloric acid ; the reac- 
tion is thus expressed; PCI,4-H, O=PCi, O+2HCI. The new pro- 
duct which M. Wurtz has described as the chloroxyd of phosphorus is 
a colorless liquid of a high refracting power, it has a specific gravity 
7 C. It emi 
of 1‘7 and boils at 110° C. It emits white vapors in the air, and by 
water is decomposed with the formation of phosphoric and hydrochlo- 
ric acids T. 8. Hont. 
3. Sulphotyarsenic Acid.—MM. Croerz and Bouquet have described 
a series of salts derived from a new tribasic acid, which 1s represented 
of arseniate of potash; its composition is AsO, S(K,). These com- 
pounds differ from the sulpho-phosphates only in the substitution of 
arsenic for phosphorus. T.S. H.

J M. Gerhardt has examined two basic nitrates of lead A when the neu- 
tral salt is boiled with litharge or treated cautiously with ammonia, a

and its formula will be NO, (Pb, H), corresponding to the tribasic
