book will take its place as the standard and authoritative work of 
reference for all original investigators in microscropic anatomy. It 
is conceived and executed in a thoroughly scientific spirit. 
3. The Rotifera, or Wheel Animalcules, By C.T. Hupson, LL.D., 
assisted by P. H. Gossz, F.R.S. (To be completed in six 
parts. Part I. London: Longmans, Green, & Co. 1886.) 
The discoverer of Pedalion and the veteran illustrator of the 
Rotiferan mastax have joined forces to produce what promises to be 
one of the most beautiful works on natural history which an English 
publisher has ever ventured to issue. The Rotifera have of late 
years been studied almost exclusively by English microscopists, and 
by none with such remarkable and profoundly interesting results 
as those obtained by Dr. Hudson. We shall be able to speak more 
fully of the work when it is completed, but at present may limit 
ourselves to a word of admiration for the plates of Floscularia. 
Each part will contain five folio plates, which the publishers would 
do well to issue in unfolded folio form with a wide margin, in a 
volume accompanying the letterpress, instead of doubling them up 
as at present. Every naturalist’s library throughout the world 
must contain a copy of this beautiful book.
