It is left for ten clays, and, after being taken up, the fluid is 

 transferred to glass bottles, which, after being corked, are left 

 standing a few days, when they are ready for sale. A large 

 amount of carbonic acid is formed in these bottles, which es- 

 capes when they are uncorked. The taste is tart and spirit- 

 uous, and is offensive before one is accustomed to it, owing to 

 the presence of fusil oils. This drink is very popular, but 

 rather intoxicating, and its use has been forbidden by the 

 Russian military authorities. 1 A, October 28, 215. 



CHLORALUM. 



The hydrated chloride of aluminium has recently been rec- 

 ommended very warmly by Professor Gamgee, under the 

 name of chloralum, as an antiseptic and disinfectant, being, 

 as stated by him, as potent as chloride of zinc or carbolic acid, 

 and at the same time non-poisonous, and free from any un- 

 pleasant smell whatever. At present it is somewhat expen- 

 sive in its preparation, although, if it be really all that is 

 claimed, some method will doubtless be devised for manufac- 

 turing it at a cheap rate. It may be prepared by mixing so- 

 lutions of sulphate of alumina and chloride of calcium,' both 

 of them cheap commercial products. In this operation sul- 

 phate of lime is precipitated, while the hydrochloride remains 

 dissolved. This may be evaporated at a gentle heat, crystals 

 forming on cooling. 18.4, September 2, 559. 



CHLORALUM. 



The new antiseptic commended by Professor Gamgee, and 

 known as chloralum, bids fair to be of much value in its ap- 

 plications in domestic economy and in medicine. The advan- 

 tages claimed are the possession of antiseptic qualities equal 

 to those of any other substance, while, used in moderation, it 

 is entirely free from smell, from unpleasant fumes, has no dis- 

 agreeable taste, and is without any irritant or poisoning qual- 

 ities. According to Professor Gamgee, by its use as an anti- 

 septic, raw-hide, meat, and other animal substances, immersed 

 in a solution of 1.030 to 1.040 specific gravity, will be pre- 

 served perfectly for an indefinite period of time, and, what is 

 still more to the purpose, will not be attacked by insects after 

 being removed from the solution. Fish, slightly tainted, 

 when immersed, recovers its freshness of appearance, and be-
