ANIMAL REPRODUCTIONS. 4329 
another: for how can we deny it, if one horn is 
completely reproduced, while the reft are invi- 
fible, or only beginning to grow? This mult be 
confidered a moft important fact in the theory of 
thefe admirable reproduétions: but I fhall omit 
{peaking of it here, as I have already endeavour- 
ed to fketch it, Part 10 of the Palingene/ie. 
On the 12 of May, I decapitated thirty {nails 
of the fame fpecies, treating them precifely fimi- 
lar to the firft: above two-thirds have perifhed. 
Thofe ftill alive regenerate varioufly, and prefent- 
ing the fame varieties, or fome analogous to thofe 
already defcribed- The months of May and 
June, and the beginning of July, have been very 
raw and wet. At fun-rife, Reaumur’s thermo- 
meter ftood at 4, 5, 6° above freezing on fome 
days in the firft week of July (1). 7 
At prefent, this difcuffion fhall be no further 
extended, for I intend to refume the fubjedt in 
another Memoir: but enough has been faid 
to prove that nothing is more certain than 
the wonderful reproduction. I know not what 
to think of the fruitlefs attempts of fome philofo- 
phers, and particularly thofe of Meflrs Adanfon, 
Cotte, and Bomare. Perhaps they have toc foon 
declared the ftate of their experiments, or taken.
