This sums up the tistoey of this meteoric shower, with as full 
an account as possible of the stones that fell at that time. 7 
the first part of this paper it was stated that this fall was qui 
as remarkable as that near L’Aigle in France in 1803. Altea 
it does not equal this latter in the number of stones that were 
collected, it exceeds it in the size of the stones that fell, The 
- . largest of the L’Aigle stones weighed 174 ibs., while the largest 
in the preserit case was 103 bbs. 
There are many points of cinag rae in the phenomena and 
circumstances <aieged the two falls. Were tt copy Biot’s 
description of a henomena "of the fall at L’Aigle as detailed
