98 SCIENCE PROGRESS 



following prefatory footnote, than which it would be difficult to 

 imagine anything more just or more generous or more scathing : 



" Je me suis toujours fait un devoir de presenter aux lecteurs 

 de ce Journal les travaux anatomiques de M. Ch. Bell. Son 

 esprit investigateur bien qu'un peu speculatif, sa grande habilete 

 dans l'art de dissequer, et son rare talent pour le dessin, lui 

 assureront toujours une place distinguee parmi les anatomistes 

 de notre epoque. Pourquoi faut-il que ce savant nuise a ses 

 travaux, se nuise a lui-meme en ne rendant pas a ses emules la 

 justice qui leur est due ? Pourquoi conserve-t-il ce patriotisme 

 barbare qui repousse tout ce qui n'est pas du pays ? Pourquoi 

 garde-t-il des pretentions a des decouvertes qu'il n'a pas faites ? 

 Sans doute parce que tel est son caractere, et qu'il n'est pas 

 facile de se changer, quand meme on en sentirait le desir. 

 D'ailleurs ce travers, que notre franchise se permet de blamer 

 en lui, est peut-etre le mobile qui l'excite au travail, et alors 

 voudrions-nous reellement qu'il ne l'eut pas ? " 



The Portio Dura of the Nerve in 1821 and 1824 



Bell's emendations of text between 1821 and 1824 are not 

 confined to the fifth nerve — corresponding emendations are 

 introduced at the same time with reference to the portio dura of 

 the seventh. This nerve in 1821 is motor and sensory, in 1824 

 it is only motor, in association with the respiratory movements 

 of the face. In the case of the seventh as in that of the fifth the 

 alterations of text are very slight but none the less significant. 

 They also occur in descriptions of experiments and of figures. 



In 1821, p. 411, "branches of the seventh are sent to the 

 membrane of the nose and to the muscles at the back of the 

 palate." 



In 1824, p. 99, the words I have italicised are omitted and 

 11 branches of the seventh are sent to the muscles at the back of 

 the palate." 



In 1821, p. 411, "Its branches penetrate to the skin accom- 

 panying the minute vessels of the cheek " and at p. 423 in 

 the explanation of Plate XXX. there is the following de- 

 scription : 



11 c. A large division of the respiratory nerve which goes to 

 the muscles of the mouth and to the integuments of the 

 cheek." 



In 1824 the description disappears. In 1830 the passage 

 disappears from the text.
