again in the cooling-tube without decomposition. No attempt 
was made to collect it separately. 
The amount of water driven off by the heat and collected in 
the cooled tube was found to be about ten per cent of the 
of a light yellowish substance was deposited in the cold part of 
the tube, which appeared to be sulphur, but was not specially 
examined. 
_ The differences in the gaseous products obtained from meteor- 
ites of the different classes may be made more apparent by 
Mnging together the results of analyses hitherto made. The. 
following table gives the total percentage of the gases yielded 
y the different specimens, the first seven being irons, the re- 
mainder belonging to the stony class. It represents the com- 
Position of the total amount of gas given off up to incipient 
or low r except in the first two instances where the 
heat, 
‘emperature employed was much higher.
