cvi. Proceedings. 



Mr. Nathaniel Waterall called attention to the fact that 

 after the recent storm sea salt was found deposited upon his 

 windows, although Croydon was about 60 miles from the sea. 

 at the point from which the wind came. 



The President said that he noticed his own back windows, 

 which were cleaned on the day previously, looked, on the 

 Saturday of the storm, as if they had had soap and water 

 thrown upon them. Mr. Jaques, of Hillside, Duppas Hill,, 

 kept some of the crystals and had them analysed, and a large 

 quantity of salt had been detected in them. The wind that 

 day travelled over 500 miles in 24 hours, and as it was about 

 sixty miles from Croydon to the nearest south-western point at 

 which the sea occurred, the wind would have brought the salt 

 to Croydon in about two hours. 



Mr. Klaassen said it had been considered that the blackness 

 of the leaves of trees was due to the spray of salt. But he 

 put this result down to a simple mechanical action. The 

 leaves were very young, and friction going on by the action 

 of the wind produced the blackness in question. He had 

 examined his own garden and elsewhere and everywhere 

 found traces of friction having gone on. 



The President had no doubt that the blackness of the 

 leaves was caused by friction, which view was also confirmed 

 by Mr. Cushing. 



After some remarks by Mr. Gill and Mr. Berney the 

 proceedings terminated. 



The following objects were exhibited: — By Mr. McKean,.
