III. DISEASES SUPERFICIALLY RESEMBLING BITTER PIT. 



PLATE XV. 



Figs. 



30. Jonathan Spot, with portion of skin carefully removed to show perfectly healthy 



pulp tissue beneath. 



31. Apple pierced by Harlequin Blip, showing dark blotches surrounding each particular 



spot where the puncture had been made. (Prom French's Destructive Insects 

 of Victoria, Part I. 1904.) 



32. Head, antennas, and proboscis of the insect. 



33. Segment of apple, showing the dark blotches beneath skin. 



IV. THE FRUIT-BUDS OF THE APPLE TREE. 



34. Cleopatra little apple about si/.e of pea, produced in the position of a terminal bud, 



but without the agency of a flower. The longitudinal section shows that it is 

 purely a vegetative growth, without any core, and that the fibro- vascular bundles 

 of the short stalk are continued right through the centre to the apex. This 

 is a clear illustration of the fact that, apart from the core, the pulp-cells and skin 

 of the apple are produced independently of the floral organs (30/6/16).
