The Physician's Visiting List (Lindsay & Blakiston's) for 1907. Fifty-sixth 

 year. Limp leather. Price, $1.00. Philadelphia: P. Blakiston's & Co. 



This well-known record system maintains the excellence of previous 

 editions. The arrangement of subject-matter is very simple, compact 

 and complete. The information given is limited to essentials given in 

 a brief but satisfactory manner. The Visiting List may be recommended 

 as a time saver if indeed it is not a necessity.

Retinoscopy (or Shadow Test) in the Determination of Refraction at one Meter 

 Distance, with the Plane Mirror. By James Thorington, A. M., M. D. Fifth 

 edition, revised. Fifty-four illustrations, ten of which are colored. Cloth. 

 Pp., xiv +67. Price, $1.00 net. Philadelphia: P. Blakiston's Son & Co., 

 1906. 



A clear, concise, condensation of the best that is known of the subject. 



The author has shown that the subject, which is looked upon as compli- 

 cated by many, is indeed a simple matter which any physician can under- 

 stand, and by following the instructions learn the practical technique of 

 making objective refractions. As the writer of this review has been re- 

 f acting objectively for the past number of years with more than moderate 

 success, without having seen a practical demonstration and having had no 

 instruction in the method other than by following Thorington's method, 

 he feels that his own experience justifies the extolling of the art with 

 which the subject is presented. 



The passing over, with but few remarks, of the use of the concave 

 mirror is to be commended, as the treating of it fully in a book of this 

 kind tends to confuse the student. 



A typographical error is found on page 40, which is liable to cause 

 considerable confusion to the beginner, especially to one who is not 

 accustomed to handle the plus and minus signs. 



The manner described of working out the refraction of an eye when 

 the scissors movement is found, is very simple and most satisfactory. 



The axonometer does not appeal to the writer, because when accessories 



are used, the entire number, including an accurate device for ascertaining 



the axis of the astigmatism is found in the Geneva Combined Opthal- 



moscope and Retinoscope, which is much easier of manipulation than the 



different accessories separately.
