coagulates from the surface inward, and envelopes the interior with a 
layer which is impermeable to water. In the latter case the soup will 
be indifferent, but the meat delicious.

_. M. Flourens, in order to compare the effects with those of asphyxia, 
subjected two dogs to the simplest kind of asphyxia produced by the 
gradual ‘consumption of the oxygen contained in a given volume of 
atmospheric air. When the asphyxia had reached the required point, 
e spinal marrow, exposed, showed no signs of feeling when cut or 
Jacerated, and only feeble muscular contractions on pinching the motor 
portion. M. Flourens hence infers that there is a marked analogy be- 
tween etherization and asphyxia. But in ordinary asphyxia, the nervous 
system loses its forces under the action of the black blood, the blood 
The matter of vegetable origin which he prefers, as being best suit- 
ed for the purposes of the invention, is cotton, as it comes into this 
country, freed from extraneous matters ; and it is stated to be desirable 
to operate on the clean fibres of the cotton in a dry state. 
The acids are—nitric acid of from 1:45 to 1-50 specific gravity, and 
sulphuric acid of 1-85 specific gravity. 
acids are mixed together in the proportion of one measure of 
nitric acid to three of sulphuric acid, in any suitable or convenient ves- 
sel not liable to be affected by the acids. A great degree of heat being 
generated by the mixture, it is left to cool until its temperature falls to 
60° or 50° Fahr. The cotton is then immersed in it, and, so that it may 
become thoroughly impregnated or saturated with the acids, it is stirred 
witha rod of glass or other material not affected by the acids. ‘The 
cotton should be introduced in as open a state as practicable. The 
‘acids are then poured or drawn off, and the cotton gently pressed by a 
presser of glazed earthen ware to press out the acids, after which it Is 
covered up in the vessel, and allowed to stand for about an hour. It is
