254 The Microscope. 



NEWS AND NOTES. 



Beginning with the present volume, Science has changed its 

 form with an idea to economy; and though it still contains the same 

 amount of valuable matter as heretofore, the annual subscription 

 price has been reduced to 13.50. It deserves a still wider circula- 

 tion. 



Dk. George H. M'Cassey contributes to the May Archives of 

 Dentistry an interesting paper on " Microscopy and Histology for 

 Office Students," which contains much sound advice, and will un- 

 doubtedly be read with profit by many who are not "office students." 



Readers who are acquainted with the writing of Mr. Ellerslie 

 Wallace, Jun., will be glad to hear that he will edit the new edition 

 of the Amateur Photographer, to which he will contribute twa 

 chapters on paper negatives, and photo -micrography. The book 

 will be issued by Porter & Coates.

 eminently practical character. All unnecessary verbiage is elimi- 

 nated to an extent often of making the statements rather dogmatic. 



The arrangement is logical. Part I. treats concisely of the 

 physiology and pathology of the urine, and discusses the limits 

 and utility of the various chemical tests. Part II. contains a syste- 

 matic scheme for urine analysis unencumbered by physiological or 

 pathological data. Chapter 1 of this part deals with qualitative anal- 

 ysis, and the student has before him a complete system which he can 

 follow through with the greatest convenience. This is followed by a 

 chapter on quantitative analysis, in which particular attention is given 

 to the ready, approximate methods so valuable to the physician; a 

 chapter on microscopical examination and one on apparatus and
