Both fluid epmpounds , when healed, are rendered solicb from the expulsion of part of the ammonia. Exposure to l~he air is attended with the same change, and the same effect is produced by the mtlriatic and carbonic acid gases. Knowing the volumes of the acid, and alkaline gase~ which combine, it is easy to calculate the proportions of each by weight in the respective salts. 100 Paa'ts consist of Ammonia. Acid.

They are the first salts that have been observed liquid, at the common temperature of the atmosphere, without con- taining water. And they are additional facts in suport of the doctrine of definite proportions, and of the relation o'f volumes. LXVI I I. Notices respect ing New Books.

Davv desdl~ihe~ the properties of a new and very extraordinary "detonating compound. It may be formed by exposing chlorine, or oxyrtiuriatie gas, to'a weak solution of ammonia, of niti'ate 0r of oxa- late of ammonia. It appears in the form of a ydlow oil, heavier than water, it appears to be composed of chlorine and nitrogene. It detonates violently by a heart bdow that of boiling water~, and even e~tplodes by a very gentle friction. It seems to be by far the most powerful explosive sub- stanceknown. Sir'H. Davy, in endeaVouring to collect the products from the exp|osion of a small particle not bigger' than a grain of mustard Seed, was severely wounded in the eye, and the vessel in which the experimerit was made warn b~'oken into pieces. Sir H. Davy stated in his letter, that the first noiice oE' Downloaded by [University of California, San Diego] at 12:41 29 June 2016 the existence of such a' substance was contained in a letter he received from a gentleman at Paris, but the manner of it~ preparation wa s not mentioned ; and th0tigh said to be dis- covered a year ago, no reference to it is made in any of thai French journat~.
