Dr. Prout intends, in the course of the winter, to deliver a 

 series of Lectures on Animal Chemistry. The object of these 

 Lectures will be to give a connected view of all the principal 

 facts belonging to this department of chemistry, and to apply 

 them, as far as the present state of our knowledge will permit, 

 to the explanation of the phenomena of organic actions. 



Dr. Thomson proposes next winter to give a Practical Course 

 of Chemistry to a very limited number of young Gentlemen, 

 who will reside in his house during its continuance. The Course

II. N.-io Example of Combustion during Combination. 



It is well known that when sulphur is made to combine with 

 copper, iron, and some other metals, previously reduced to 

 powder, and well mixed, the compound becomes red hoc, and 

 glows like a live coal just at the instant of its formation. The 

 same thing takes place when phosphorus is made to unite with 

 lime, barytes, and strontian. When quicklime is slacked in 

 obscurity, it frequently becomes luminous : and there is little 

 doubt that the same thing would happen to barytes and strontian. 

 Chevreul has lately observed that when barytes or strontian is 

 heated in contact with muriatic acid gas, the gas is absorbed, 

 and the earthy salt formed becomes red-hot. There can be little
