Sii. Notice regarding the Ionian Melon and the Malta Melon. By 

 Mr. Daniel Crichton, Gardener to the Right Hon. the Earl of 

 Minto. Read August 2. 1827.

 red spider, of which there appear to be several species.

 over with a mixture of tobacco liquor, sulphur, and a little 

 turpentine during winter ; and no insects of any kind appear 

 during the following summer.
