He also published an elemental work. Elements of Astronomy, in 1813, 

 and 1819, which was the class-book of his course in Dublin. Each line 

 beams with astronomy, whether it regards calculation or observation. 



After having enumerated so many works on astronomy and 

 pure mathematics, it would have been interesting to have added 

 to this long list the titles of various papers on Botany and Le- 

 gislation. I have been informed that Dr Brinkley took a deep 

 interest in these sciences, and prosecuted them with success ; 

 but I have not had time to examine, if, in the Transactions of 

 any of the Societies, there is any of his botanical descriptions, or 

 any of his discussions upon legislation.
