888 Niemann on the Action of Ethylene on Chloride of Sulphur. 
240°C. It forms a yellowish-green liquid, somewhat imsoluble 
in water, but miscible in every proportion with alcohol and ether. 
Heated in a platinum spoon it takes fire, and burns with a clear 
flame. 
Neither the zine nor the baryta salts crystallize. The potash 
salt crystallizes in a wavellite-like mass. The copper salt forms ° 
microscopic blue needles. 
By the action of chloraceticacid on the soda compound of phe- 
nylic acid, Heinz obtained a new acid, phenoxacetic acid,

of soda. acid. 
The new acid is isomeric with the next higher homologue of 
salicylic acid, C14 H® 0%, or, as is more probable, with Gerland’s 
oxybenzoic acid. 
Phenoxacetate of baryta, C'*H’ BaO® + 3HO, is obtained by sa- 
turating the free acid with baryta water. It crystallizes in very 
large, thin lamine. Phenowacetate of copper, C}®H? CuO’ +2 HO, 
forms small tabular or prismatic cerulean crystals, which are 
very little soluble in water. Phenoxacetate of lead forms small 
microscopic granules, Phenoxacetate of silver, C1’ H? AgO®, forms 
small, flat prismatic crystals, which are frequently arranged in 
groups. 
Phenoxacetie acid, C'® H8 OS=C!* H7 rh 02. The free acid 
may be obtained from any of its soluble salts by the addition of 
a strong mineral acid. Accordmg as the decomposition is 
effected in the warm or in the cold, the acid is precipitated as 
an oil, or as an amorphous powder, which by agitation becomes 
crystalline. In the temperature of the water-bath it gradually 
disappears. 
The brown liquid produced by the direct action of chlorine on 
sulphur has been found by Carius to be a mixture of subchloride 
of sulphur, S? Cl, with bichloride of sulphur, 8 Cl?. Niemann * 
has tried the action of ethylene gas on this body. When the 
dried gas was passed into the chloride, it was rapidly absorbed 
with disengagement of heat, and the colour changed from a 
brown to that of the pure bichloride. When this change of 
colour was complete, the absorption ceased; for ethylene gas has 
no action on bichloride of sulphur. The product was then treated 
with dilute soda ley, by which sulphur was deposited. A large 
quantity of water was added, and the whole submitted to distil- 
lation. A yellowish oil passed over, which was washed with water, 
and dried over chloride of calcium. It seemed to boil at about
