swarming with Tylenclrus, was referred for examination to Dr. 

 Masters. 



Snowdrop Mildew. — The Rev. C. Wolley-Dod sent decayed 

 bulbs of Snowdrop. He wrote : " These are Snowdrop bulbs of 

 which the leaves last year showed slight symptoms of the Snow- 

 drop mildew. Often there is no trace left of the bulb in the 

 following spring. I lose all my best Snowdrops from it, and 

 have as yet found no remedy. These were dressed with solution 

 of sulphate of copper last year when in leaf." Dr. Masters said 

 he had successfully prevented the disease by treating bulbs of 

 Iris reticulata with sulphate of copper before planting. 



Effect of Fog. — Dr. Masters showed panes of glass from glass 

 houses at Gunnersbury and Feltham with a dense black deposit 

 due to fog. Mr. Morris stated that 20 square yards of glass at 

 Kew produced, when scraped, 20 grammes of solid matter. This 

 could not be removed by mere drenching with water, and the 

 whole of the glass in the Royal Gardens would require scrubbing 

 to cleanse it. Dr. Oliver said that an analysis of the deposit 

 showed that 20 per cent, consisted of tarry and oily matters. 

 Dr. Masters also showed Rose leaves which had fallen off under 

 glass in consequence of the fog. No details had been sent. 



Abnormal Mushroom. — A Mushroom with a very large gouty 

 stem was shown. There was no history to it. The stem was 

 much split longitudinally. 



Magnolia conspicua. — Dr. Masters showed a photograph taken 

 last year of an unusually fine plant in bloom at Gunnersbury 

 House.
