Experiments with Gymnosporangium Juniperi. — On Saturday, 



rminating 



sporangium Juniperi on two small pieces of moist blotting-paper, 

 and then placed these on two leaflets of a young mountain ash, 



time. I likewi 



placed some spores, not on blotting-paper, on the back of a third 

 leaflet. The blotting-paper, &c, was moistened from time to time 

 by a spray-bottle, but during the three days considered necessary 

 by me they were unfortunately allowed to become dry several 

 times. The plant was kept in my room, without the protection of 

 a bell-jar. The experiment seemed to have failed, because I was 

 not able to detect the pustules produced by the first appearance of 

 the spermogones ; however, in the autumn, on returning after two 

 months' absence, one of the lacerated leaflets was found to have 

 mature llustelia cornuia. On Monday, June 13th, with Gymno- 

 sporangium Junijxri spores which were germinating very freely, 

 producing a great number of pro-mycelium spores, I inoculated a 

 young mountain ash, placing some spores naked on the leaflets, 

 others on blotting-paper, on the upper and under surfaces respect- 

 ively, without lacerating them. The plant was kept under a bell- 

 jar, and freely moistened by a spray-bottle from time to time. On 

 the morning of the eighth day spermogone pustules made their
