Mr. Jasper W. Rogers communicated a paper " On the Potato 

 disease," which led to a long discussion, in which the Chairman, 

 Dr. Ayres, Dr. Cooke, Mr. Taylor, Dr. Bossey, and other members 

 joined.— G. E. D. 



A numerously attended meeting of the Botanical Society of Lon-

 to exist upon the minds of some members of the Society as to the 

 quantum of food and nutriment stated by him in his essays to exist

 to be found in the potato when in its proper state of health, although
