242 The Holler Prohe-Platte. By J. Edwards Smith, 
Eemarks. — It will be noticed that the figures corresponding to 
the last three or six shells are considerably below those formerly 
published; it is, however, probable that the figures above given 
will not be materially changed. Professor Morley's determination 
of A, pellucida as above given, agrees very well with Colonel 
Woodward's observations. — A Paper read before the Memphis 
Microscopical Society, reported in the * Cincinnati Medical News* 
February^ 1875.
