390 ANIMAL REPRODUCTIONS. 
at leaft, obfervations feem to indicate this, for 
the conical papilla preceding an arm, is no larger 
than that preceding a hand. Probably the body 
of a newt includes a number of germs of diffe- 
rent kinds, appropriated to the various reproduc- 
tions that are to enfue, and each germ is placed 
in the fituation and manner _ beft correfponding 
to its evolution. But 1 fhould refer to what is 
faid on the fubject, Part g. 10, of La Palinge- 
nefte. 
A fixth refult arifes from the evolution of the 
fingers and toes. It is not effected in the fame 
proportion as evolution of the arm and leg. 
Now, when I write this, the tenth of Oétober, 
the new arm and leg of the newt, which was mu- 
tilated 6 June, have nearly attained the fize of 
the original members, while the regenerated fin- 
gers and toes have not acquired half their natu- 
ral fize; yet they are perfectly well formed; and 
execute all the fungtions peculiar to thefe parts. 
The feventh and laft refult is prefented by the 
trunk of the mutilated members. While the ‘Te- 
producing part unfolded, I never obferved any 
elongation of the trunk. In this refpect, there 
is a coincidence with the ftate of the trunk of 
earth worms, and of thofe frefh water worms 
which I multiplied by fetions thirty-fix years 
ago; and the truth of this obfervation may be 
judged of, by infpecting fig. 2. 3. Jo. 12.17. 22.
