390 ANIMAL REPRODUCTIONS. 
On the 31 of July, for the fecond time, I cut’ 
off the reproduced hand and foct of my newt ; © 
the fingers and toes being then about a line long,

reproduced hand and arm the third time; and, on 
the 13 of O&ober, performed the fourth opera-

extremity, by fuch repeated amputations,
