wholly dissolved, under the use of muriate of ammonia^ 

 Dr. Ritterbandt's method is protected by patent, and I 

 have here some copies of his prospectus. The method is 

 equally well adapted for stationary and for locomotive en- 

 gines, and well deserves a trial. I do not consider that 

 it supersedes the need of chemical analysis, since this would 

 be as available as ever in determining beforehand whether 

 a water is likely to fur or not ; and where it is found that 

 it will, or where incrustation has already taken place, an 

 analysis of the water will determine the exact quantity of 

 muriate of ammonia needful in each case. 



This method appears applicable to domestic boilers, where 

 steam alone is wanted ; but I think it is not where the water 

 itself is to be used. 



After a few remarks from Mr. W. S. Ward, the meeting 

 broke up.
