packets or plants in soil, or fruit are disinfected by carbon bisul¬ 
phide; rose cuttings from reliable dealers apparently clean are 
dipped in a solution of Bordeaux mixture : if Scales are present, 
they are treated with hydrocyanic gas. Cotton seed for planting 
are steeped in a solution of corrosive sublimate, whereas cotton 
seed in bulk for oil extraction is treated with sulphur dioxide by 
means of a Clayton apparatus using a strength of 5 per cent, under 
pressure for twenty-four hours. Full details as to the methods of 
disinfecting, the construction of fumigating chambers and the 
quantities of chemicals used in each case are given in the public¬ 
ation above referred to. The communication made by Sir Daniel 
Morris has a distinct value in setting forth for the first time a 
complete system of dealing with the diseases of tropical plants 
based on experience extending over many years. (Vol. Il, flémoires,

for. The study of entomology has a great attraction to many 
young men, who have been prevented from following it up because 
it was thought it would lead to nothing. We now know upon 
responsible authority that the demand for qualified entomologists 
exceeds the supply, and young and able men, who find the study

mankind without injuring their own prospects. 
M. R. Mayné (Bruxelles) fait savoir que le Gouvernement 
belge crée également en ce moment un service entomologique 
pour sa colonie et que des entomologistes seront prochainement 
envoyés au Congo pour l’étude des maladies des plantes provo¬ 
quées par les Insectes. 
Mr. H. Rowland-Brown inquired whether similar benefits
