 Beet, which were referred to Chiswick for trial. 



Mr. J. O'Brien, Harrow-on-the-Hill, sent good examples of 

 Jamaica Oranges. 



Mr. Sidney Ford, Horsham, sent fruits of Apple King of the

Messrs. Saltmarsh & Sons, Chelmsford, sent seedling Apple 

 Chelmsford Wonder, which the Committee desired to see again in 

 February or March, with specimens cooked. 



Messrs. T. W. Beach & Sons, Brentford, sent an interesting

SCIENTIFIC COMMITTEE. 



Dr. Maxwell T. Masters, F.E.S., in the Chair, and seven 

 members present. 



Diseased Grapes. — Grapes received from Mr. Barron were 

 exhibited, attacked with fungoid disease. Dr. Masters pointed 

 out that the disease had been described by Mr. Worthington 

 Smith, and called attention to its resemblance to and possible 

 connection with " scald," a much commoner complaint in which 

 no fungoid growth has been described. 



Soil for Alpine Plants. — The Bev. C. Wolley-Dod showed 

 samples of burnt clay, which he had found the best soil for 

 Alpine plants. To a great extent it prevented the growth of 

 Marchantia, and was soft and friable, and far superior to broken 

 brick. The cost of burning was about a shilling a ton. Pro- 

 fessor Church undertook to examine the chemical composition 

 of the earth used. 



Effects of Frost. — Dr. Masters showed leaves of Aucuba 

 blackened and killed by exposure to a temperature of — 2° Fahr. 

 on the night of November 28 at Croydon. This exceptional 

 temperature was independently confirmed. The Aucuba is among 

 the hardiest evergreens. The variegated leaves appear to suffer 

 most from frost. 



Abnormal Development of Bulbs. — Dr. Masters showed bulbs.
