turned quite clear by the portion of the aorta which remain- 
ed attached to the heart. This done, he injected into the 
ulmonary artery a green solution of the chamelion mineral 
which had been well protected from the air: it returned to 
the aorta unchanged in colour. He then tied the aorta, in- 
jected a fresh portion of the same fluid, tied the pulmonary 
artery, inflated the lungs, and kept up, during several mi- 
nutes, an artificial respiration. The injected liquid soon ac- 
quired in the pulmonary vessels a fine red colour.—Jbid. 
Note. This experiment only proves that when the lungs 
contain no venous blood, but mereiy a fluid which has a 
——e — for oxygen, the latter may pass through the 
the lungs and form the combination. It could 
not eis have been doubted that the coats of the pulmonary 
blood vessels are permeable to air, since the carbon finds its | 
way through them. The experiment of Prof. M. has too 
little analogy to the living function to justify any inference, 
we think, with respect to the absorption of oxygen by the 
ood; aud, in our opinion, the results of Allen and Pepys 
stand unimpeached. : G. 
21. Thermometer.—M. SKENE, a lieutenant of the royal 
marines, who accompanied Capt. Parry, in 1820, proposes 
a new division of the thermometric scale. His plan is to 
consider the space between the freezing or melting of mer- 
cury and the freezing of water, as one degree, and divide it 
into 100 aise. and to extend. this division to the higher 
9 degrees, &c. These numbers would be more easily re- 
tained in the memory than those in common use. The gra- 
duation of thermometers on this plan, would, it is true, be 
more difficult than at present; but, by being confined. to the 
most — hands, greater —_—— ag perfection would ; 
be secured.— Revue Encyc.. Mar
