Scientific Committee, June 12, 1894. 

 Dr. M. T. Masters in the Chair, and five members present. 

 Lilium candidum Diseased.— Specimens were sent by Mr. 

 G. Tebbutt, of Mogden House, Isleworth, with the following 

 observations : " The plants were attacked last year, but not to 

 such an extent as now. This year the bulbs were transplanted 

 to a fresh place, but the disease has become worse. It will be 

 noticed that the bulbs themselves are strong and healthy, with 

 very little sign of fungoid growth, while the stems and leaves are 

 badly attacked. In the same patch of ground are L. chalcedo- 

 nicum, L. tigrinum, and L. Martagon, but not one of these shows 

 signs of the disease. Tulips which now occupy the ground planted 

 with L. candidum last year have also been attacked." Dr. Masters 

 suggested spraying with Bordeaux mixture early in the season, so 

 as to reach the bulbs and young leaves. Such a method would 

 be protective, but not necessarily curative. The disease itself 

 is fully described by Prof. M.Ward in "Annals of Botany," ii. 

 page 319. 



Pears Damaged by Frost. — Dr. Masters exhibited several 

 small Pears, black and decayed, the result of the great frost in 

 May. 



Droppers in Snowdrops. — He also showed specimens of this 

 peculiarity, which is more commonly known in Tulips. 



Monstrosities. — He also exhibited the two forms of " Peloria " 

 in Calceolaria — 1, a true reversion to a regular " sleeve" -like 

 form ; 2, a fourfold repetition of the " slipper " — as well as a 

 Laelia with three lips (true peloria), and the subvirescent spathes 

 of Aroids. 



Photos, from Transvaal. — Dr. Masters also exhibited some 

 illustrations of trees, &c, but, excepting a fan-shaped Mimosa j 

 they were not determinable. 



Trifolium subterraneum. — He also showed specimens and 

 drawings of this Clover found at Folkestone. A full description 

 of its method of burying the unripe pods and deriving nourish- 

 ment by means of the hairs will be found in Darwin's "Move- 

 ments of Plants," page 573. 



Horse Chestnuts Cankered. — Specimens and photos, of a badly 

 diseased tree were received from the Superintendent of the Eoyal 

 Victoria Park, Bath, with the following remarks : " The tree was 

 planted (one of six) about sixty years ago : three of the six have
