The limits prescribed to this paper will permit only a very brief 
discussion of the preceding catalogue. The region of country 
included by these showers, down to that of A. D. 1799, extends 
from England to China, about 130° in longitude, and from about 
20° to 51° N, latitude. 'The table above shows the dates (when- 
ever they could be found,) reduced to the Gregorian calendar, 
which, thus stated, will indicate with sufficient accuracy the point 
of the earth’s orbit, in each instance intersected by the meteoric 
stream. It is reasonable to presume that some of the dates are 
erroneous, and that some of the cases were not actually meteorl¢ 
showers. Much caution is therefore necessary in tracing the cor- 
respondence of dates between these ancient star-showers and 
those of the present age, especially as our knowledge is so 1m 
perfect regarding the meteoric seasons which now exist. The 
shower of April 20, 1803, may be the lineal successor of those of 
April 10, 1095 and 1122. That of August 2, 1243, may be the 
ancestor of the meteoric sprinklings of August 10, seen at the 
present day. It does not appear certain which of these ancient 
showers is represented by the modern shower of November 13. 
There is some reason to suppose that those showers which are 
described as continuing all night, (e. g. Nos, 4, 5, 9,) may have 
occurred in the summer season. sd 
Previous to 1833, we have no precise observations on the post 
tion of the point of radiation during any meteoric showe!, but
