vitality with characteristic indifference and fatalism. 
POWER-ALCOHOL AND STARCH FROM MACROZAMIA. 
In connexion with the investigations which the Institute has carried 
out regarding the macrozamia and the possibility of using this plant as 
raw material foy the manufacturing of industrial alcohol and starch, 
it is interesting 10 note that, since the results of the investigations were 
made available, the Forestry Commissioners of New South Wales have 
invited tenders for the right to operate on Zamia palms, the price 
“tendered to be at a rate per ton of dry starch obtained from the palms. 
The immediate practical value of the investigations is thus apparent, 
since important information was obtained regarding the starch con- 
tained in the plants. 
ENTOMOLOGICAL RESEARCH IN ENGLAND. 
The British Board of Agriculture and Fisheries has established an. 
Entomological Laboratory at Rothamsted, where a Chief Entomologist 
and two research assistants are to devote their whole time to investiga- 
tional work. It is also proposed to appoint twelve advisory entomo- 
logists, one for each of the twelve agricultural divisions in England. 
CONCENTRATION OF SWEET CIDER BY REFRIGERATION. 
The Weekly News Letter of the United States Department of Agri- 
culture for 10th September, 1919 (Vol. VII., No. 6, p. 3), describes 
a process by which sweet cider is concentrated by mechanical refrigera- 
tion. The fresh apple juice is frozen, and the frozen mass. is crushed, 
then subjected to centrifugation. The frozen water is thereby separated 
from the mother liquor which contains the solid matter of the apple 
juice. Five gallons of juice yield 1 gallon of syrup concentrate. This 
concentrate has better keeping qualities than ordinary cider, and 
remains sweet indefinitely if kept in cold storage. By addition of water 
it may be restored to its original volume, condition, and flavour.
