tainly implicated. My own opinion is, that these 

 nuclei gave origin to the tubercle corpuscles, in con- 

 sequence of receiving from the blood peculiar nu- 

 trient matter. In the lung I have seen appearances 

 which point to a similar conclusion."* Would not 

 these views arise from appearances precisely analo- 

 gous to those represented as giving support to the 

 view, that tubercle originates in the peri vascular 

 sheaths of bloodvessels ? The views of Beale, II. 

 Charlton Bastiau,f and Cornil,J would then consti- 

 tute simply different modes of expression of the same 

 truths. 



ROBIN, F. A., POUCHET, 1867. 



Robin, who may be considered the mouthpiece of 

 the French school of histologists, reduces the human 

 body to elementary parts, usually microscopic, which 

 he calls anatomical elements. The forms he makes 

 threefold, -fibres, tubes, and cells. 



The fibres are generally of considerable length, 

 sometimes extending from the lower part of the

% Our information with regard to M. Robin's views, is de- 

 rived from an admirable exposition of them published in vol. iv, 

 1867, of the New York Medical Journal, by Dr. Wm. T. Lusk, 

 who there states that he has them mainly from a course of familiar 

 and private instruction, furnished to him by M. C. H. Georges 

 Pouchet, son of the eminent physiologist, Prof. F. A. Pouchet, 

 Assistant to M. Robin, Lecturer upon Anatomy and Histology to 

 the Ecole Pratique, author of " Un Precis d'Histologie," &c. ; so 

 that they may be said to be the views also of the elder Pouchet.
