CORRESPONDENCE WITH SCIENTIFIC MEN. 37 



from my laboratory, except that in the analysis of the 

 waters of Carlsbad, in Bohemia, which I visited the last 

 summer, I discovered several substances which have not 

 before been found in solution, such as the fluate of lime, 

 the carbonate of strontian, the phosphate of lime, and that 

 of alumina. These substances are found dissolved in free 

 carbonic acid. The tufa which these waters deposit are 

 like arragonite, which establishes the idea of Mr. Stro- 

 meyer, that it is the carbonate of strontian which deter- 

 mines the arragonite form of this species of the carbonate 

 of lime. 



I do not possess the work of Mr. Cleaveland, 



and I doubt whether it is to be procured in London. I 

 venture to beg you to purchase a copy for me ; I have re- 

 quested Mr. Hughes to repay you the cost 



STOCKHOLM, June 28, 1832. 



SIR, I pray you to accept the accompanying five vol- 

 umes of my Chemistry, as a testimonial of my esteem and 

 consideration, not to say gratitude, . for your kindness in 

 sending us your excellent Journal. The work which I 

 send you is not yet finished ; but 1 thought it best not to 

 wait longer, that you may not lose entirely the gratia novi- 

 tatis of the first volumes. The sixth volume should already 

 be out, although I have received no notice of it, nor had 

 any copy sent. The entire work will consist of eight vol- 

 umes. The sixth will still be on vegetable chemistry ; the 

 seventh on animal chemistry ; and the eighth on the oper- 

 ations, manipulations, and instruments of the laboratory, as 

 well as a treatise on crystallography, of which Mr. Mitscher- 

 lich is the author. My translator having been seized by 

 the cholera, has been for a long time dangerously ill from 

 the consequences of this dreadful disease, which has been, 

 especially in France, so disastrous. The work is therefore 

 suspended for the moment, and I shall probably not have 

 the pleasure of sending the rest to you till the next year.
