No. G. — Pea (1858); three seeds; prepared soil; without nitrogenous manure. 



Ji /ne 5, — Three peas previously set died. Three more set to-day in prepared soil, with 

 ash that had been neutralized with sulphuric acid, and gently re-ignited; and the pot 

 placed over sulphuric acid and covered with a glass shade.

 with the shades, as we waited some time in the hope that M. Yille might be able to come over and super-
