M. de Beauvois having followed some mushrooms through 
all their developments, perceived that they changed their 
form in such a manner, that some botanists have placed 
them in different genera, according to the age at which they 
observed them: thus the rizomorphus of Porsoon is only 
the second age of the mushroom, which becomes a true 
dolet mushroom in the third; the dematrium bombianum 
of the same author becomes at the end of some time his

make it resemble a morell, and also finishes by becoming a 
true Jolet mushroom. But this plant has need of a little 
light to enable it thus to run through all its stages. 
The researches on the natural history of animals have 
heen Jess numerous than those on botany, but they have not 
been deyoid of interest. 
M. de Beauvois has begun to publish the insects he col- 
lected in America and on the coast of Africa. Two num- 
bers of them have already appeared. 
M. Cuvier has continued the two great branches of re- 
searches in which he has been occupied these some years 
past, upon animals without vertebre, and upon the fossil 
ossifications of quadrupeds. 
_In the former of these branches he has this year given

eolide,
