Sir Charles Miles Lambert Monck, Bart, communi- 

 cated to the Meeting, on the 16th of July, Directions for re- 

 moving Worms from the roots of plants grown in pots or tubs.

 believe that worms might be the cause of the sickness ; he 

 therefore directed a pint of an infusion of Walnut leaves to be

 other plants in pots, and it was attended with equal success. 

 He thinks that, the infusion is beneficial not only in destroy-

 m full growth, and therefore most in want of moisture and
