ANIMAL REPRODUCTIONS: 407 
more complex ftructure, are in the fame manner 
reproduced in the reft of the limbs with equal fa- 
cility and regularity. ‘Thus it may eafily be con- 
ceived, if the fkin of the tail is flathed, if various 
deep incifions are made into it, and flices of dif- 
ferent fize cut out along the vertebra, that na- 
ture has only to heal the wounds, and repair the 
lofs of the pieces. This I have myfelf beheld ; 
and fhall relate but one inftance. 
A flice about an inch long, and two lines 
broad, was cut from the tail of a large newt, 7 
Auguft 1778. The wound immediately healed ; 
and from the 15, I faw a thin tranfparent flice all 
along the length, appropriated to replace the 
part taken away. Ina few weeks, reproduction 
was complete, and the regenerated portion could 
not be diftinguifhed from, the reft of the tail. 
ReFLecTIons.—If thefe experiments are com- 
pared with thofe of the preceding Memoir, it is 
evident that they all coincide in confirming the 
refults and conclufions relative to many phyfiolo- 
gical facts found in nature. Among thefe is the 
pre-exiftence of germs deftined to repair loft 
- members: 
When, with the view of explaining this rege- 
neration,* we recur to the powers of relation, an 
expanjive or vegetative power, an effential force, 
internal moulds, and organic molecules, we certain-
