the rise and progress of disease. It is indeed strange to 

 observe the time of even accomplished chemists dissipated 

 on subjects of but small value, while the magnificent chemistry 

 of the atmosphere is neglected.

Farther Bemarks on the Intermitting Brine Springs of KiS" 

 sing en. By Professor J. D. FORBBS. 



On the 7th of January 1839, I communicated to the Royal 

 Society of Edinburgh a pretty detailed account of the singular mineral 

 and gas springs of Kissingen, in Bavaria, then much less known than 

 at present to English travellers. I refer to this paper, printed in the 

 Edinburgh New Philosophical Journal, April 1839, for the details of 

 the most curious of these, a saline spring called Kunde-Brunnen, which 

 was at that time regularly periodic ; a copious and turbulent dis- 

 charge of brine, mixed with torrents of carbonic acid gas, recurring 

 six or eight times in the twenty-four hours. This phenomenon, 

 exactly as described in my paper, appears to have continued with 

 slight variation ever since, that is, for a period of twelve years,
