a number of ed worms. I have since examined nearly, if not quite, a 

 dozen of the plants from Bexley Heath, and in most of them there were 

 the hollow space and the broken-up cells, but not a single eelworm could 

 I find, which surprised me very much. These creatures pass part of 

 their existance in the soil, and it is just possible that they may have 

 left the plants for that purpose, The roots were much curled and 

 twisted about. I could not find any sign of insects or fungi." With 

 regard to eelworms in the soil, Mr. Douglas observed that they were 

 killed if the fresh loam w T as stacked with London dung while the latter 

 fermented (four loads of loam to one of- dung). Mr. Odell stated that 

 e?l worms were often found in the dung of animals fed on clover-hay, 

 proving a source of infection. 



Fasciated Gourd. — Mr. Odell showed a remarkable Gourd, which had 

 the stem closely joined to the fruit-wall along one side. A tendril was 

 growing from the stem about the middle of its junction to the fruit. 

 All the fruits produced on the plant while it was young were similar 

 to this, but those produced later were normal. 



Carpentaria, Diseased Leaves of. — Dr. Cooke gave the following 

 report : — " The leaves of Carpentaria are badly affected with leaf -spot of 

 a very common kind, produced by a fungus of the genus Phyllosticta, 

 although the species is not very decided. In such cases it is advisable to 

 collect and burn all the diseased leavesjpossible, and not to allow them to 

 remain on the ground, as they are liable to develop a higher form of 

 fructification in the winter, and produce sporidia in the spring, which will 

 attack the young and healthy leaves. Spraying with Bordeaux mixture 

 in spring at intervals of a fortnight may i prevent the spread of the disease." 



Apple Scab dc. — A letter was handed in by Mr. C. H. Hooper, in 

 which attention was drawn to the prevalence of Apple scab this season, 

 and of moulds on Apples in the fruit store. His correspondent said :— " I 

 think I shall master it by burning a piece of sulphur the size of a pea on 

 a piece of live coal twice a week. But I have little doubt formalin 

 (40 per cent.) is the proper remedy to prevent the growth of fungi in a 

 fruit store. . . . One cannot be too careful about the kind and condition 

 of wood used for shelf -fixing (slate shelves are in use). Many sorts of 

 fungi start from wood." Several members mentioned the great abundance 

 of " scab " this season. 



Flora of the Belgian Sand Dunes. — Dr. Masters showed a number of 

 photographs illustrating the physical features and flora of the dunes of the 

 Belgian coast, the Botanic Garden at Coxyde among the dunes, and the 

 method of retaining the sand by the growth of Poplars and other means. 



Scientific Committee, December 13, 1904. 



Dr. Masters, F.R.S., in the Chair, with nine members present, and 

 Messrs. W. G. Freeman, Watson, and Hillier, visitors. 



Eelworms in Mignonette. — Mr. Saunders further reported on these :— 

 u 1. The worms, after making their way into the plant, feed on the contents 

 of the cells. In the two plants from [Hillingdon, both, just at the point 

 where the root ends and the stem begins, were hollow, and the cells round
