The fascicle of papers as sent to us contains one of some 

 interest, " Sur Influence que Introduction de Fair atmospherique 

 dans le mout qui fermente exerce sur la fermentation." The 

 apparatus used for this was a brass capped glass cylinder traversed 

 by a rod movable about its longitudinal axis bv clockwork 



. a o axis by 



mecftamsm, and supporting four spirally-arranged brass rotating 



fans at its extremity. The object of this was to bring all parts of 

 the liquid thoroughly in contact with air, which was introduced 

 through four pipes of peculiar construction screwed into the bottom 

 of the cylinder. The following table shows one of the series of 

 results obtained upon comparison with liquids into which air had 

 not been introduced : —
