94 LOUIS PASTEUR. 



M. Biot, M. Dumas, M. de Senarmont, and M. Balard. 

 M. Biot especially was his habitual confidant. The 

 day when M. Biot learned that Pasteur proposed to

 however, further insisting upon the point, that he 

 would not advise anyone to occupy himself too long 

 with such a subject. M. de Senarmont alone took
