These experiments show that the blood is capable of ■feibsbrbing 

 l-g- times its volume of" carbonic acid, a result which has also been 

 obtained by otHert^fbservers. They moreover show that it is capable 

 of absorbing from 10 to 1 2*5 per cent, of its volume of oxygen 

 from the atmosphere, consequently 10 to 12 times more than water 

 under the same circumstances,* aijd thj^ tbei'*t)s(>j:'ptiojp jof^nilij^en

{! The author then shows, that from some observations upon the 

 quantity of the inspired air and of the blood which flows into the 

 dungs in a given time, we may conclude that the blood does not 

 absorb more than half the oxygen which the experiments above de- 

 tailed have shown to exist iji it. This portion is each time consumed 

 in the capillary vessels, and the remainder, amounting to the other

i>r-,Mj-Sti.Rose remarks, that the earlier analj'^ses of this substance 

 are discordant, on account of the imperfect separation of the titanic 

 acid and oxide of iron. The titaniferous iron of Egersund in Norway 

 has been analysed by M. Mosander, M. Kobell and M. H. Rose ; the 

 results obtained by the two first agree pretty well, but differ con- 

 siderably from those of M. Rose. 



In three operations on the above-named mineral M. Mosander ob- 

 tained the following results :— ° '•'"'• '
