e68 ANIMAL REPRODUCTIONS. 
But M. Lavoifier is not the only academician 
awho has feen the reproduction, as we learn from 
the memoirs of the Royal Academy. ‘ Since Sig. 
‘ Spallanzani’s difcovery, many {nails have been 
* decapitated. From the obfervations communi- 
* cated by Meffrs Turgot, Tenon, Heriffant, and 
* other philofophers, the head was completely fe- 
‘ vered from fome {nails ; of others, longitudi- 
£ nally fplit up, and one half taken away; and 
6 fome had the horns cut off, or pulled out. 
‘In about a month, a protuberance forms in 
‘the middle of the fection, which gradually 
‘ grows, and at laft becomes a new head, pro- 
‘ yided with its mouth and teeth. M. Herifflant 
* has demonftrated that thefe teeth are reproduc- 
‘ ed, having fhewn a fevered head, with the teeth, 
© preferved in the fpirit of wine, though there 
« were alfo teeth in the regenerated head of the 
¢ fame {nail.’ 
‘ The horns are not reproduced until the head 
‘is entirely formed ; and their growth preferves 
‘no uniform rule.’ 
Thefe are all the experiments, fa far as I know, 
made in Paris. And I have next to fpeak of 
thofe undertaken by other naturalifts, in different 
parts of Europe: and, as I am defirous of con- 
tinuing the fame chronological order which J 
have hitherto endeavoured to preferve, we hall, 
in the firft place, advert to a treatife by Muller
