170 A. W. Wright— Gases contained in Meteorites, 
been subjected to further examination, with the result of mod- 
ifying somewhat the conclusions there arrived at. That it has

character of the carbon di-oxide, as in the presence of, or com- 
bined with. water. But in this case the carbonates formed by 
as well as absorbed within it, With a view to test the correct- 
ness of this supposition, a special set of experiments was under- 
taken. A quantity of the substance of the Iowa meteorite was 
red heat.- The following were the results obtained :

Although, from the nature of the case, no very precise result 
could be sa eth from this mode of experiment, inasmuch as it 
was Impossible either to Separate the iron entirely from the min- 
eral portion, or to free the iron completely from the ston y matrix, 
_ the numbers above given indicate clearly that the stony por- 
_ tion yields a considerable portion of the gas given off at the

which, on the other hand, is richer in hydrogen. The product
