Fossils, which the Author is preparing for the Palseontogra-

Various circumstances have operated in preventing the pub¬ 
lication of this Catalogue at the above date: nor, as so much 
time has elapsed, would it have appeared at present, had it 
not transpired, that there was an attempt being made to 
forestall the Author’s labours by one, to whom he had un¬ 
reservedly communicated every particular of the views he 
entertained, on the local Permien Fossils, up to the Autumn 
of 1846,—the time when all correspondence ceased between 
them. 
With respect to the Monograph, it is necessary to state, 
that its publication has been delayed by the late protracted 
illness of the Author: it is expected, however, to be com¬ 
pleted in a short time.
