ANIMAL REPRODUCTIONS. 331 
foundation. I have, as every one has had, re- 
* productions, even very immediate ones, of 
‘ horns, heads, lips, and other parts; but thefe 
‘ were reproductions of parts that had not been 
‘ entirely cut off: for all the heads, I fay, the 
‘ real heads, all the horns, all the jaws, and the 
‘ other parts which have been completely cut 
‘away, and only a quarter of a line from the 
‘ origin, never exhibited any kind of reproduc- 
‘tion, far lefs a complete regeneration. Let us 
‘be ftrid, and inveftigate the truth. All who 
‘ have mutilated {nails, and firft Sig. Spallanzani, 
‘ have certainly been deceived. ‘hey have thought 
‘the head was fevered, when the cap only has 
‘been cut off: they have believed that they fe- 
¢ parated or eradicated the horns and jaws, while 
‘the origin always remained; whence it is not 
*‘ wonderful if reproductions enfued. Thefe, you 
“ will candidly admit, are not reproduétions, or 
‘ rather regenerations, fuch as you, M. Trembley, 
‘and Reaumur, had feen in frefh water worms, 
‘ the polypus, the claws of lobf{ters—How many 
‘ well credited operations have deceived perfons, 
‘ lefs familiar than us with fimilar operations and 
‘the anatomy of fhelled animals! They have 
¢ thought that they had completely cut of fo many 
‘-heads, horns, and mouths, beyond the origin, 
‘ which, in every journal and _ periodical paper, 
‘ they have fo liberally regenerated. 1am well
