increase in softening. No further giowth took place even on slices 

 kept for 10 to 20 days. 



Potato. It grew with great rapidity ou raw potato, ir the form 

 of a moist, creamy, yellow, spreading growth with marked softening 

 In five days, slices 20 m.m. thick were completely softened and could 

 be cut with a platinum needle. There was a depression in the centre 

 and an ammoniacal smell. Nessler's reagent oave a distinct colora- 

 tion to the water extract of the inoculated potato, indicating the 

 presence of ammonia. Tincture of iodine did not color the inoculated 

 potato blue, the starch was, therefore, destroyed. 



Celery. In two days there was a moist whitish grov/th with 

 yellowish discoloration and considerable softening. In 7 days the 

 softening was more extensive and the discoloration brown. 



Tomato, (ripe). After two days, there was a slight growth at 

 •seat of inoculation. In 7 days there was rotting and cracking of the 

 skin with whitish growth extendiug from the cracks. The inside 

 was quite soft. 



Green Tomato behaved in the same way, but growth was some- 

 what quicker. The first indication of the disease was slight discolor- 

 ation or premature ripening of the inoculated part followed by 

 e.xudation of water and softening and later by cracking of the skin 

 and progressive softening. 



Artichoke. (Jerusalem). In 24 hours the surface growth was moist 

 and dirty white in color, and there was softening beneath surface to 

 a depth of about 7 m.m. outside the circle of growth the tuber had 

 become red brown in color. In 48 hours the softening was deeper 

 with pitting of the aflfected portion. Color around the afiected portion 

 became reddish. In 4 days the whole tuber was soft. 



Asparagus. The upper third portion of the Asparagus stem 

 (the edible part) was the first part to rot, presenting a water-soaked 

 appearance. On the third day after inoculation, the middle third 

 commenced to soften and on the fourth day, the lower third began to 

 do the same. The pieces gradually collapsed and a dirty white skin 

 formed on the surface. 



Horse Radish. Softening of the tissue, even of the hardest and 

 most woody parts, to a depth of 2 - 4 m.m. occurred in 48 hours. 

 There was a whitish growth on the surface, gas bubbles formed, and 

 the centre of the stem fell in. Tne odor on the third day was quite 

 pronounced and very objectionable.
