 ABSTRACT. 



Mr. J. Sullivan, a pupil in the laboratory of the Techno- 

 logical Museum, has successfully manufactured a hydrated 

 chloi-ide of aluminum and calcium for use as a styptic and 

 antiseptic. The chief ingredient used is the kaolin from 

 Bulla Bulla, a township a few miles north-west of Mel- 

 bourne. Mr. Sullivan mixes the kaolin, a silicate of alumina, 

 with lime, forms this mixture into bricks of a convenient 

 size, and burns them in a furnace or kiln. When the decom- 

 position has taken place, the bricks are crushed and treated 

 with hydrochloric acid, then evaporated to dryness to 

 separate the silica from the soluble chlorides, which are 

 washed out with water. 



The solution being made of any desired strength, when 

 desired for medical purposes it is proposed to crystallize the 

 chlorides, so that solutions may be made of known strengths. 

 Many trials have been made with these solutions with 

 gTeat success, showing it to be a very valuable styptic and 

 disinfectant, having all the properties of the "Chloralum," 

 a disinfectant lately introduced in England. It has been 

 tried by several of the leading medical men of Melbourne, 

 both in hospital and private practice, and their testimonials 

 are submitted. 



Drs. Neild and Blair spoke of their successful experiments 

 with this disinfectant.
