mixtures. The hydrate in thin plates, was put into solutions 

 of muriate of lime of different densities, but of the temperature 

 of 32° Fahr. It seemed to remain in any part of a solution of 

 specific gravity 1.2, but there was constantly a slight liberation 

 of gas ; and, as minute and imperceptible bubbles may have 

 adhered to the hydrate, the result can only be considered as a 

 loose approximation. The solid crystals would probably be 

 heavier than 1 .2. 



The hydrate of chlorine acts upon substances, as might be 

 expected, from the action of chlorine upon the same substances, 

 and it may perhaps now and then offer a convenient form for 

 its application in experiment. When put into alcohol, an ele- 

 vation of temperature amounting to 8° or 10° took place. 

 Tkere was rapid action, much ether, and muriatic acid formed, 

 and a small portion of a triple compound of chlorine, carbon 

 and hydrogen. 



When put into solutions of ammoniacal salts it liberated 

 nitrogen gas, formed muriatic acid, and also chloride of 

 nitrogen, which remained undissolved at the bottom of the 

 solution. In aqueous solution of ammonia similar effects were 

 produced, but less chloride of nitrogen was formed. 



In order to arrive at a knowledge of the composition of this 

 substance, I adopted the following process. The crystals were 

 collected together by a small quantity of solution of chlorine, 

 then filtered and pressed between successive portions of bibu- 

 lous paper, at a temperature of 32°, (care being taken to expose 

 them as little as possible to the air,) until as dry as they could 

 be rendered by this means. A glass flask with a narrow neck, 

 and containing a portion of water at 32°, having been previously 

 counterpoised, a portion of the crystals were immediately after 

 the last pressing introduced into it ; they sank to the bottom 

 pi the water, and the flask being again weighed, the quantity 

 of crystals introduced was ascertained. A weak solution of 

 pure ammonia was then poured on the water in the flask, care 

 being taken to add considerable excess over that required by 

 the chlorine beneath. The whole was left for twenty-four 

 hours, in which time the chlorine had had sufficient op-
