 bearing Branches of different Colours. In a Letter to the 

 Secretary. % Thomas Andrew Knight, Esq. F.R.S. $c 

 President. 



Read February 4, 3 812. 

 My dear Sir, 



I mentioned to you, in the last spring, that I had a new 

 variety of Grape, which had remained sound and excellent 

 till the 27th of April, without any further care than that of 

 suspending the bunches in a room at the top of my house, 

 which was very damp ; and I promised to send a bunch of 

 it to you, during the present winter, for the inspection of the 

 Horticultural Society. A severe frost, however, upon the 

 3rd of April last, almost wholly destroyed the produce of the 

 only bearing plant I possessed of this variety, no fires having 

 been lighted in the house in which it grew ; and a very small 

 bunch, with green berries, the natural colour of the Grape 

 being black, with white stripes, is the only one I am now 

 able to send you. The coloured berries appear to shrivel 

 considerable less than the green, when long kept, possibly 

 owing to the pores of the skin being partially occupied by 

 the colouring matter. 



The coloured berries, when the stripes first begin to appear 

 upon them, in ripening, present a very singular and beautiful 

 appearance : and the leaves, which are green during the
