it will therefore be advisable to place the manometer in a thermostat. 

 Cj) to this time the manometer was placed in a glass vessel, throngh 

 which the water of the aqnednct flowed. If a correction is rendered 

 unnecessary h\ keeping the manometer at constant temperature, the 

 greater sensitiveness of the aniline-water-nianometer will be still more

For the comparison of the results of the determinations of the

1) After having read my publication in the Archives Néerlandaises, Batelli made 

 some mea.siuemenl.s with a manometer wliicli dilVered from mine only in so far, 

 that it was eiected in reversed position, in order to make the closure with mercury 

 instead of with oil possible. This change was sufficient, as Prof. Cassuto, 

 under whose superintendence Batelli seems to have worked, wrote to me, to omit 

 my name altogetlier in the publication in the Ann. de Ghim. el de Phys. T. XXY

 Na OH, Nao CO:i oi' gliiss, which causes the aniline to run in a tube of the aqueous 

 solution, and to which the great accuracy is actually due.
