caustic alkali, and the final result consequently bears but little 

 resemblance to the original object. Speaking of spiders, the 

 author states that "a North American species, Lycosa arenicola, 

 (Scudder), makes a structure resembling a huge bird's-nest." 

 Probably "huge" has crept in by mistake; "tiny" would be 

 nearer the truth. The use of the term "figure" in this work 

 may possibly be somewhat misleading. There are no figures in 

 the text, each of the sixty-five illustrations occupying a full- 

 page plate. Natwre through Microscope and Camera can be 

 strongly recommended to any one in need of a gift-book for a 

 youth, it being certainly a step in the direction of popularising 

 the study of microscopy. F. P. S.

This valuable little book wall be hailed with delight by every 

 practical microscopist, containing, as it does, directions for the 

 manufacture and use of everything from a slide to a compound 

 microscope. It is a digest of a very large amount of information 

 on microscopy culled from Work, of which journal Mr. P. N. 

 Hasluck is the editor. The condensation and arrangement of 

 this information has been carried out in a most praiseworthy 

 manner, and the absence of technicalities will render the book 

 intelligible to all. Every page bears the impress of practicability, 

 and it is most pleasing to find that there is no tendency to 

 perpetuate the whims of individual authors. I refer to such 

 recommendations as the slicing up of bottles to make cells and 

 the use of a razor in the cutting of echinus spine sections, both 

 emanating from well-known writers. Microscopes and Accessories 

 can be heartily recommended to any one who knows anything 

 about the microscope, or who wishes to. F. P. S.
