A table spoonful « of brown sugar is sufficient in this manner, 
for a salmon of five or six pounds weight ; and if salt is desired, 
a tea spoonful or more may be added. Saltpetre may be used in-

Art. XI . — Account of the Memoires de la Societe de Phy- 
sique et d’Histoire Naturelle de Geneve. 
This is the first part of a volume of natural and physical 
science, published by a society of Savants” of Geneva. The 
society itself was constituted so far back as the year 1790, and 
many of the communications made to it, have, from time to 
time, been given to the public in different scientific journals, or 
in the particular works of their respective authors. By the 
present publication, it spires to a more permanent character, 
and seems destined to take no mean station among the various 
philosophical societies and scientific institutions of Europe, 
Among its members we recognise many names already highly 
distinguished in the scientific world, and others which, though 
at present less known, will, we have no doubt j sustain the high 
reputation which their predecessors have acquired. Having al- 
ready exhibited to our readers a list of the memoirs which form 
this portion of the first volume of the society’s labours % we 
shall proceed to notice a few of the principal papers. 
In his Memoir on the Fall of Leaves,” M. Vaucher objects: 
to the hypothesis that attributes the fall of the old leaf to the 
growth of the new bud ; to that also which ascribes it to an al- 
leged superabundance of juice in the plant, and defective tran- 
spiration; or to the inequality of growth between the circum- 
ference of the stem and the petiole of the leaf. The true cause.
