less, as it has been extended since his time ; but they are the 
first revelations on this subject, and which none but the in- 
ventive genius of Newton probably would ever have made, 
though succeeding mathematicians such as the Bernouillies, 
Euler, De Lambert, Clairaut, and above all, La Place, have 
admirably improved the tools, and consequently very much 
refined the workmanship of our great author, and for which, 
I trust, they have amply been repaid by the eulogies of the 
learned world. It cannot be said, that they have, to any 
considerable extent, enlarged the philosophical or mechani- 
cal principles on which all their theories are founded. The 
are those of Newton, and no other could enable them by 
@ priort deductions, to draw forth all the minute irregulari- 
ties of the moon and other sattelites, of the motion of the 
comets in their eccentric orbits, and of the innumerable 
actions of those bodies, one on another. We may here con- 
clude this number, which I much fear will prove too long for 
the reader, with a quotation from that elegant scholar and 
great astronomer, Dr. Halley.

-Durine a jaunt made last month, in company with Dr. 
and Mr. William Cooper, to the tertiary region of 
New-Jersey; we had the good fortune to disinter and to bring 
to the city the Skeleton, nearly entire, of a mastodon, or 
oth, as it is colloquially, but improperly termed. 
_ We were induced to search for these remains, from having 
seen lately exhibited at the Lyceum of Natural History, a 
tooth, which maerod upon examination, to belong to this in- 
genus, which was said to hay d near
