It was foundthat ilf, or by volume, is decidedly interesting feature of the results with alcohol isthat the increase of permeability is reversible. If theincrease be carried too far it is not reversible (or at 190 INJURY, RECOVERY, AND DEATH least recovery is incomplete); in the first experimentsthis condition was unintentionally realized and led thewriter to suppose that alcohol behaves like ether. Thecourse of a typical experiment is shown in Fig. 83. Thetissue was first placed in a mixture containing 970 water + 30 Squibbs absolute alcohol + about 15 -V. X Alcohol ) Sea Water.

The mixture had theconductivity of sea water; the concentration of thealcohol was M ( by volume). The net resist-ance rose to 110% in the course of 40 minutes. The tissuewas then placed in sea water containing M alcohol( by volume); and in the course of 20 minutes theresistance fell to The tissue was then placed insea water and the resistance again rose to 1007o. The facts that recovery occurs in alcohol, and thatirregular fluctuations are often observed in experimentson recovery from ether, suggest that the difference ANESTHESIA 191 between tlie behavior of alcohol and the other
