408 Meteors of November, 1868. 
Its central point may be regarded as 54 miles high, over N. lat. 
40° 43’, and W. lon. 76°, and its course 8. 78° W., with an 
angle of depression of 20° upon the horizon of the places be- 
neath it. The heights of its eastern and western ends were 
and 49 miles or 95 and 79 kilometers, 
Motion of the train of the meteor. 
The upper end was borne westward so that as seen from 
Washifigton the cloud was foreshortened. The central and 
lower parts were seen projected upon this upper part. Hence 
the bifurcation and the cavity described by Prof. Eastman. 
The elliptic form and the oval cavities seen at Haverford are 
also, in part at least, the effect of perspective. 
the southward motion of the lower end at Haverford, 80 
miles from the cloud, was 25°, and at New Haven, 175 miles 
distant, was 8° or 10° during two thirds of the period of vis- 
ibility. These imply a motion of at leust 40 miles, or about @ 
mile per minute. 
We must therefore assume that just below an elevation of 
about 50 miles, there was a rapid north wind, which swept the 
lower portion of this cloud with jt southward, The wind may 
have come from one or two points east of north, Above this 
there was a south wind, (or 8. 8. E.,) whose velocity may have

By its downward motion, the eastern end of the cloud was
