The International Annual of Anthony's Photographic 

 Bulletin. Edited by W. Jerome Harrison and A. H. Elliott. Crown 8vo, 

 pp. xix. — 489. (London : Ilifte and Son. New York : E. and H. T. 

 Anthony and Co. 1890.) 



The third issue of this important annual is before us. It contains upwards 

 of two hundred articles on every subject relating to photography, contributed 

 by nearly as many writers, many of them of world-wide celebrity in their 

 profession. The plates, which are very numerous, are excellent — each in its 

 own special method of production. 



Traite Pratique de Photographie : Appliquee au dessen 



industriel. Par Amedee Masselin. Crown 8vo, pp. 134. (Paris : Gauthier- 

 Villars et Fils. 1890.) 



Without entering into the chemical and optical theories involved, this 

 treatise gives precise instructions in photography, sufficient for architects, 

 engineers, and others to acquire a practical knowledge of the art. 



La Photographie Judiciaire : Avec un appendice sur la 



Classification et I'identification anthropometriques. Par Alphonse Bertillon. 

 (Paris : Gauthier-Villars et Fils. 1890.) 



A treatise on forensic photography, showing the precautions which should 

 be taken in photographing criminals to insure identification. Of course, no 

 retouching is allowed, as every freckle or other mark must be carefully 

 |3Teserved. There is an interesting chapter on anthropometry. 



La Photographie sans Maitre. Par Eug. Dumoulin. 



(Paris : Gauthier-Villars et Fils. 1890.) 



This introduction to photography is especially addressed to beginners. 

 The author recommends the ferrous -oxalate developer for time exposures and 

 hydroquinone for instantaneous work. A formula is given for eikonogen, and 

 directions are given for making a pinhole camera. 



Manuel d'Heliogravure et de Photogravure en Relief. 



Par M. G. Bonnet. (Paris: Gauthier-Villars et Fils. 1890.) 



A description of two modes of photo-mechanical printing. In one process 

 a copper plate is covered with bichromated gelatine, exposed to the light under 

 a negative and then treated with perchloride of iron, which eats away the 

 surface of the copper under those parts of the gelatine film not hardened by 

 exposure to the light. In the other process the prints are taken direct from 

 the gelatine film. 



La Photographie Aerienne. Par cerf-volant par Arthur 



Babut. pp. 74. (Paris: Gauthier-Villars et Fils. 1890.) 



Photography, by means of a kite, is a perfectly practical proceeding for 

 any photographer understanding instantaneous photographing. M. Babut 

 minutely describes the different apparatus used ; he shows the means of obtain- 

 ing considerable heights, and of raising even without wind the camera by means 

 of a kite, and of knowing exactly the vertical height at which the operation will 

 be effected. A charming photograph illustrates the work, and shows how 

 successful the style of photography may be made in a campaign or voyage of 

 discovery.
