The want of a medium of publication of its proceedings, etc., 
has been felt for some time by the Natural History Society, 
and the issue of this Bulletin has been commenced to supply 
this want. 
It is intended to continue the publication in this form, from 
time to time, of original articles read before the Society ; and the 
Council request that other Societies and Public Bodies who may 
receive it, will send their publications in return.
