A minute quantity, of what appeared to be carbonaceous 
matter, was mixed wi e residual traces of oxides found in 
the mother-water. It is very evident from the above propor-

The calculation of the daubréelite is based upon the sulphur 
found in the analyses (48-26). As yet we do not know of any 
“ tial mineral corresponding to this, and it is an interest- 
Ing fact that we are already enabled to establish so clearly its 
€ composition, and also to obtain good characteristic speci- 
Mens that will find their way into the principal cabinets of 
meteorites, :
