full of fmall oblong clear white fubftances, which 
one would fuppofe pieces of fat, or glands. The

fainter, and im a certain time, which is according

creafes. Then we obferve one or two crofs 
brown lines, occupying the middle of the new 
tail, which indicate the fite of the vertebrae and 
the veflels. The firft evolution is defigned, fig. 
223 the part reproduced, x, is thinner and more 
tranfparent than the reft ; the brown line, ¢. At 
the extremity, is a {mall internal cavity, m, very 
perceptible in the figure, which I have uniform- 
ly found in reproducing tails. This tail had 
been divided on the 11 of July; and onthe 12 
of Augutt the reproduced part was about three 
lines and a half long, and four and a half in dia- 
meter, at the bafe. 
The new portion was ten lines in length, 2 
September, and fhaped exadly like the tail of 
a newt. I could obferve no difference be.

‘thofe of tails unmutilated. It was again defign-
