^o8 NATURAL SCIENCE. September, 1896. 



accruing from experimental research, such as the discovery of the 

 circulation of the blood, with its vast influence on all modern surgery, 

 and the diphtheria anti-toxin. We would recommend this sensible, 

 moderate, and humane paper to all the well-meaning but ignorant 

 class who wish to abolish, not to restrict, vivisection. In the issue 

 for July 10, there is another common sense paper, touching on this 

 topic, entitled ** Physiology in the Schools," by S. H. Gage, of Cornell 

 University. 



The PJiotogram for August has a very serious note on a communi- 

 cation made by Dr. Baraduc, " a curer by means of animal magne- 

 tism" to the Societe de Medecine, in which he states that his "vital 

 fluid " is "a very real force," and deflects magnometers placed near 

 his hands. " If dry plates (in darkness) be used instead of magno- 

 meters, the one opposite the right hand will be found on development 

 10 show cloudy masses, while the left hand causes dots like a shower 

 of raindrops. . . . Carrying the matter a step further, the doctor 

 finds that by firmly concentrating the mind on a definite object, so as 

 to distinctly visualise a picture thereof, the image may be impressed 

 upon a dry plate. He has found it necessary to concentrate his 

 thoughts for periods varying from ten minutes to two hours, and the 

 difficulty (for most folks an impossibility) of clearly visualising a 

 thought, and of concentrating the mind thereon for any length of time, 

 forms the great drawback to the process." We leave our readers to 

 comment upon this. This number also contains some very beautiful 

 reproductions of photograms of Warwickshire scenery, of which 

 " Guy's Mill," by Dr. J. W. Ellis, deservedly gained the first prize. 



Through a difficulty connected with the appropriation-grant 

 for the U. S. Department of Agriculture, the publication of the journal, 

 Climate and Health, has been stopped. 



The Scientific American published a special double number on 

 July 23, its fiftieth birthday. 



A new illustrated entomological journal is announced from 

 Neudamm. It is called Wochenschrift jiiv Entomologie, and the sub- 

 scription is three marks per quarter. 



A nnnaire des Mttsces scientifiqnes et archeologiques des Departements and 

 L'Ainiee biologique, under the direction of Yves Delage, are announced 

 from Paris.
