(J.) The advantage we had from the 
Tnjedion of this Compofition into the 
fjidD^^^-^, was, that we very diftindly 
faw the figure and the whole ilrudure of 
it when theCompofition wherewith it had 
been filled, was refrigerated and hardned. 
For we found, that ^itduBns did afcend 
unco the right fide of the heart, keep- 
ing one and the fame fize,which was no 
more than of an inch ^ that after- 
wards it was enlarged to | of an inch in 
diameter ^ that in this enlargement its 
tunicle on the right fide of the vertehr<t 
was , as *twere , pierced by four fmall 
holes, diftantT^^ of an inch from one a- 
nother, and ail difpofed in arowf, into 
which holes the faid Compofition had not 
been able to penetrate that the fame 
^;/^///, after having retaken its firft fize, 
had two appendixes faftiioned like facks ^ 
that there was yet a third appendix beneath 
the dijatation ?/7^f the firft and higheft 
appendix was of the form andbignefsof a 
fmall phafeolus S that the third , which 
was beneath the dilatation, was like to the 
fecond-,^W they had all a ftreight orifice 
and the lad was full of chyle confpif- 
fate, ifo that the Compofition could not 
enter there, as it had done into the other^ 
The Importance of thefe Obfervations 
ought to incite the Curioiity of thofc that 
are addided to Anatomical refearches , 
and to engage them to examin with care
