o In another analysis. M. Francis obtained 0'75 per cent, of nitrogen. The picrotoxine employed 

 for these analyses was partly obtained from the manufactory of M. Merck, in Darmstadt, and was 

 partly prepared by M. Francis himself; it was perfectly white, and beautifully crystallized. Reg- 

 nault, as is well known, found no nitrogen in this compound.
