Prof. Benjamin Peirce, of Harvard University, has published the fol- 
lowing communication relative to the comet, in the Boston Courier, un- 
der date of March 26, 1846. 
“ Having been unable to satisfy the observations made by Mr. Wm. 
C. Bond, the director of the observatory, upon the comet discovered by 
his son Feb. 26, by any parabolic orbit which I could obtain, I have ap- 
plied the general method of computation to the observations of Feb. 26, 
March 9, and 18. I have obtained the following orbit, having a period 
of revolution of 95 years, which completely satisfies the observations of 
Feb. 26, and March 1, 2, 3, 4, 6, 9, 10, 11, 12, 17, 18,21. The pe- 
riod of revolution cannot be relied upon as accurate within several years, 
but if the comet should be visible as late as June or July, I think it may 
be determined within a year. There seems a reasonable expectation 
that it will be seen at that time, and I hope the telescope of 44 inches 
aperture just received at the observatory, from Simms, of London, will 
enable Mr. Bond to take observations upon it.

“The small difference in the elements between this orbit and Mr. 
Geo. P. Pond’s parabola, arises almost wholly from the introduction of 
the period of revolution as an element of calculation.”
