30 Prof. Evans on the Guernsey Co. (O.) Meteor of May 1, 1860. 
Art. VIL.—On the Path and Velocity of the Guernsey County (Ohio) 
ation of May 1st, 1860; by Prof. E. W. Evans of Marietta 
ollege. 
In a brief account of this meteor published in this Journal of 
Science, July, 1860, I gave the most reliable and definite obser- 
vations which I had been able to collect, bearing on the question 
of the meteor’s path and velocity; I also gave such conclusions 
as the data seemed to me to warrant. I propose now to review 
the subject more at length, in the light of all the facts now in 
my possession ; partly in order to state, in a more careful man- 
ner, both my conclusions and the arguments by which they 
seem to me to be established; and partly in order to correct 
some serious errors, in regard to the data, which appear in for- 
mer communications on this subject. 
Prof. J. L. Smith, of the University of Louisville, in an arti- 
cle published in the January number (91) of this Journal, begins 
by summing up “all the observations” which he considers “ wor- 
thy of note respecting the fall of this meteorite.” In this sum- 
mary the statement is repeatedly made, that the village of New 
Concord, near which the largest stones fell, is nearly east from 
the village of Cambridge, at which some of the observations 
which he records were made:—it is also stated that a large 
number of stones fell southeast of Cambridge. The truth is 
that New Concord is nearly west of Cambridge, and that not 
one of the stones has yet been found to have fallen southeast of 
the latter place. 
On the map contained in Prof. Smith’s article, the lines of lat- 
tude place the fall of meteoric stones full 60 nautical miles far- 
ther north than it really oceurred; while Parkersburg, the place 
of a most important observation quoted by him, 
far north by about 37 nautical miles. Such erro 
to stand uncorrected, would involve the whole subject of the 
meteor’s path in confusion. 
Among the observations which Prof. Smith selects as note- 
worthy I find the following. ‘Mr. D. Mackley of Jackson 
county states that he was standing on the platform of the rail- 
road station in Berlin, 20 miles south of Parkersburg, when he 
saw in a northeast direction a ball of fire about 80° above the
