224 On the Periods of Flowering of certain Plants. 



Meeting of the British Association at Southampton in September 

 last, that I was aware of a paper to the same effect respecting 

 Brussels having been read by M. Quetelet before the Academy 

 of Sciences of that capital, on the 7th of February 1846. A no- 

 tice of it appeared in the ^L^Institut^ Journal of August 12 

 (No. 658. p. 272). Very few plants are there named, and such 

 in my lists as are of the same species have been noticed in con- 

 nection with them.]
