BUST ON APPLES. 



he last meeting of the British Pomological 

 ?, J. Gr. Graham, Esq., read a paper giving 

 ult of microscopic examinations of the dis- 

 l spots on apples. As the disease is quite 

 mt in this country, the following extract 

 fr. G.'s paper will be read with interest, 

 my first examination of the Apples you sent 

 )nslsting of Margil, Summer Nonpareil^ 

 f Nonpareil, Spanish Pearmain, Byson 

 and Golden Drop — all affected in the same 

 r with indented discolored spots — I was of 

 1 that the injury was caused by the presence 

 mycelium of some mildew, which was not 

 eveloped, and the rind of the fruit in too 

 and tough a state to admit the fructifying 

 3f the mildew to penetrate through it. In 

 ;o ascertain this point, I adopted the same 

 i which I applied when I first observed To- 

 1 to be spotted like diseased Potatoes — viz., 

 ist my finger nail through the skin, and thus 

 the mildew, if it were there, to come out. — 

 anticipated, in twenty-four hours the same 

 1 as that which was destroying the Potato 

 lis infestans,) was visible on that part of the 

 in full fructification. 



ith regard to the Apples, the process was 

 ; and, as they were very dry, no mildew 

 'ed until I put them in a damp place, soon 



The first is of a gelatinous color ; the latter is at 

 first white then grey, and lastly dirty green. I 

 ought also to state that when I first received the 

 Apples, I carefully examined the tissue beneath 

 the spots, under the microscope, and found the 

 mycelium of the mildew traversing the cells in all 

 directions ; and, as is usual in all such cases, the 

 parts thus infested had become brown, being in 

 fact killed by it ; some suppose by feeding on and 

 exhausting their proper juices. I am also of 

 opinion, that the threads of these mildews are 

 very short-lived, and, dying amongst the cells, 

 communicate decay to them. 



" I should also mention, that at the time I made 

 the incision in the spots, I also picked out small 

 portions of the Apples where there were no spots ; 

 and on these parts no mildew whatever has ap- 

 peared up to the present time. I can, therefore, 

 but draw the conclusion, that the spots are caused 

 by the mycelium, or spawn, of the mildew above 

 mentioned.

The Balsams, to which the present species be- 

 longs, affect shady, damp localities, and the de- 

 cayed mould of large forests in both hemispheres ; 

 they are annual and perennial plants, with cylin- 

 drical stalks and branches, smooth, frequently 

 swollen at their articulations, and filled with a 

 very abundant watery juice ; the leaves are alter- 

 nate or opposite, nearly always dentated, and 

 unprovided with leaf scales.
