ON CHLORINATED CHLOROHYDRIC ETHER. 
peutic properties as the chlorinated Dutch liquid. It is colorless, 
very fluid, having an aromatic ethereal odor, analagous to that of 
chloroform, but more resembling that of Dutch liquid ; a sweet 
and stimulating taste ; is completely without action upon litmus 
paper ; with difficulty soluble in water, though perfectly and 
readily dissolving in alcohol, sulphuric ether and most of the fixed 
and volatile oils. It is not inflammable as are the officinal ethers 
and Dutch liquid; bearing resemblance in this point to chloroform. 
Its specific gravity not being uniform, and its boiling point vary- 
ing with the density, from 110° to 130° centigrade, clearly indi- 
cate that this body is not an unique substance, but is constituted 
of several others of different densities and elastic tension.* 
Inasmuch as the different chlorinated chlorohydric ethers all 
possess the same anaesthetic properties, and it would be a matter 
of impossibility completely to separate them, we propose to desig- 
nate the liquid which they form by the generic name of chlorinated 
chlorohydric ether. 
Such are the principal properties of this new anaesthetic liquid, 
which we think, with Dr. Aran, is called to play an important part 
among local sedatives. — UAbeille Medicate, Jan. 28, 1851. 
Flourens on Chlorinated Hydrochloric Ether. — A new substance 
has been proposed by chemists, as possessing in a very high degree 
the power of suspending the sensibility of the tissues in animals 
submitted to its influence. M. Flourens (on the 20th instant) in- 
formed the Academy of Sciences of Paris, of some experiments he 
has lately made, with the view of studying the effects of chlori- 
nated hydrochloric ether upon animals. The learned physiologist 
has subjected several dogs to the inhalation of this ether (prepared 
by M. Ed. Robin,) and all of them were affected with general 
anaesthesia, some in from three to four minutes, and others in four 
* The reaction of chlorine upon chlorohydric ether, gives rise to four 
ethers, viz. : the mono-, hi-, tri- and quadrichlorinated ; the mono- and bi- 
chlorinated being the first obtained and the easiest to prepare, but too vola- 
tile to be advantageously employed as local anaesthetics. Treated with an 
excess of chlorine, they are converted into the tri- and quadrichlorinated 
ethers, which are much more dense and less volatile. The two last men- 
tioned compounds, constitute more particularly, the chlorinated chlorohy- 
dric ether. — Annates de Chem. et de Phys. lxxi. 353.
