sometimes very destructive to trees at Turin. He also found 

 eggs at the points of the shoots, which appeared to be those of 

 some aphis. 



Fem-prothallus with Water Pores (?). — With reference to 

 the accumulation of water upon the prothalli mentioned at a 

 previous meeting, Professor Ward thought it was quite con- 

 ceivable that water might accumulate in the tracheids beneath 

 the surface ; but, on the other hand, it might have been merely 

 dew-drops, the evidence being insufficient to furnish a more 

 definite conclusion. 



Ivy -leaved Pelargonium diseased. — Mr. Morris showed leaves 

 of plants received from France and grown at Chiswick, badly 

 diseased with a new species of Glceosporium. There was no 

 remedy known, and complete destruction by burning was the 

 only thing to be done. 



Effects of Hail at Kew. — He also showed leaves of bedding- 

 out plants, and mentioned a long list of others injured in various 

 degrees by the hailstones, which had riddled and lacerated them 

 on July 15. Aquatic plants suffered in the same way. Some of 

 the genera most severely injured were Funkia, Nicotiana, 

 Polygonum, Gourds, Podophyllum, Malvaceae, Saxifraga peltata, 

 Rheum, Boragineae and Solanacere generally, and Gunnera 

 scabra. Fortunately there was no damage to the glass-houses. 



Peas diseased. — Mr. H. L. Pownall, Lenton Hall Gardens, 

 Nottingham, forwarded specimens of Peas badly attacked by 

 fungi. He reports that for years there have been patches of it, 

 but this season it is very bad indeed. It was referred to Dr. 

 Oliver for examination and report. 



Plum Leaves blighted. — Mr. J. Lloyd-Bozward, of Worcester, 

 had forwarded specimens to Kew, which Mr. Morris exhibited to 

 the meeting. The blight had not been previously observed at 

 Worcester. After the attack the leaves shrink up, wither and 

 die, as if burnt, and the ends of the spring shoots, some 7 or 8 

 inches in length, die also. The leaves are mostly marked with 

 discoloured patchess of a faint dusky red colour. Dr. Masters 

 said that he had received similar specimens from various dis- 

 tricts. No fungus could be detected by Dr. Cooke, and no insect 

 appeared to be the cause ; but Mr. Yeitch and other members of 

 the Committee had little doubt but that the affection was due 

 to the wood having been badly ripened in the previous year.
