degree of perfection. Some of these I have occasionally pub- 

 lished ; and I am not without hope of being able, in the course 

 of time, to lay a practical system of chemistry before the public. 

 One part of this system indeed, that which respects the gases, I 

 have nearly completed. But salts, metals, and minerals, present 

 so very extensive a field, that I am apprehensive lest the life of 

 one individual should be too short to traverse the whole of it. I 

 take this opportunity of calhng the attention of chemists to 

 the importance of such a desirable object. The joint labour of 

 many may accomphsh with ease what would surpass the most 

 gigantic efforts of a single individual. 



Thus have I finished my remarks on Mr. Brande's Review of 

 my System of Chemistry. When I perused it for the first time 

 with attention in the month of February last, the impression 

 which it left upon my mind was, that many of the animadversions 

 mustbe well founded. They are made with an air of such con- 

 fidence and plausibility that they are well calculated to make an 

 impression on the reader. After having thus investigated them 

 one by one, I am amazed to find how very few of them have any 

 justice in them, and feel fully confident thc.t every reader will 

 participate in my astonishment, and agree with me that a more 

 uncandid review has scarcely ever appeared, and that it fixes an 

 indelible stigma both on the editor and the author.

The occultations of the stars by the moon were made under very favourable circum- 

 stances, and their brilliancy remained undiminished till obscured by the dark limb of 

 the moon.
