Scalding. This affection seems peculiar to certain 

 varieties of grapes, and to Lady Downes's seedling in 

 particular, just as it approaches the stoning stage. I 

 have frequently had berries sent to me so affected. 

 One side of the berry looks as if it had been suddenly 

 scalded with hot water, and the part affected collapses 

 and decays. It is caused by heat, and the only way 

 to prevent it is to keep the vinery well ventilated and 

 cool by opening both the top and bottom lights. When 

 the grapes begin to swell after stoning, there is no 

 further fear of its appearing.
