 desires to acquaint himself with the theory of the microscope 

 or who wishes to add to his present knowledge of the subject.

A passing notice of this work must suffice, as it would seem 

 altogether out of place for the Club critically to review the work 

 of its own President. We cannot, however, refrain from warmly 

 congratulating the author upon his practical successes in photo- 

 micrography, as strikingly exemplified in the plates with which 



this volume is embellished.

Catalogues. — We have received from several opticians catalogues 

 of microscopes and appliances, of which two seem deserving 

 of special mention. 



C. Baker, of High Holborn, is responsible for a very complete 

 list of microscopes and microscopical apparatus, and is to be 

 complimented upon the exceedingly systematic arrangement 

 adopted. The extremely varied assortment of articles which a 

 modern first-rate optician is expected to stock renders cataloguing 

 a by no means light task, and we are always grateful to a firm 

 who issue a list of which the arrangement is intelligible to the 

 public as well as to themselves. This catalogue is supplemented 

 by a list of second-hand instruments, which is issued quarterly, 

 with the exception of the June quarter. 



P. & J. Beck, of Cornhill, have produced a catalogue of micro- 

 scopical apparatus which is really a work of art, and, in addition, 

 contains a wonderful amount of valuable information concern- 

 ing the employment of the appliances described. The series of 

 apparatus for the examination of pond organisms is particularly 

 complete, from the ancient frog-plate to the modern compressors.
