236 Variation in the Colour of Cross Impregnated Peas, 



That this is incorrect, is not here " determined by a more 

 able physiologist," but by the above statement — by the above 

 fact ; for the effect was strikingly evident in the seed, which 

 was changed by the impregnation from a deep blue to a yel- 

 lowish white. And if the seed undergoes such a change, why 

 may not the fruit ? It is more than probable that it does ; 

 but, the change not being so conspicuous as the difference 

 between blue and white, it has escaped observation. Perhaps 

 the most effectual way to unravel the mystery of the anomaly, 

 would be to impregnate a considerable number of Peach 

 blossoms with the pollen of the Nectarine, and to examine 

 minutely if any change succeeded in the fruit. 



If this communication should be thought worthy to appear 

 in your Transactions, I trust Mr. Salisbury will excuse an 

 humble attempt to reflect a little light on an obscure part of 

 a science in which he himself is so luminous.

 Previous to the receipt of the above communication, one 

 on the same subject was transmitted by Alexander Seton, 

 Esq. and read at the Meeting of the Society on the 20th of 

 August, 1822. Mr. Seton had happened to make a similar 

 experiment, by impregnating the flowers of the Dwarf Im- 

 perial, a well known green variety of the Pea, with the pollen 

 of a white free growing variety. Of the flowers so treated one
