JOURNAL OF THE EOYAL HORTICULTURAL SOCIETY. 



Society by Professer G. E. Stone, on the various forms of fungoid 

 diseases which infest Cucumbers, Tomatos, and Lettuce when culti- 

 vated in and under glass. Among the ten fungus diseases peculiar to the 

 Cucumber it is explained that what is called the damping off" disease 

 is due to a fungus, and remedies are suggested for this and other diseases. 

 It is an instructive article, and English cultivators may glean some hints 

 from it, as most fungoid diseases of plants are not peculiar to any country.
