Thus water boiled free of oxygen, and charged very feebly with chlorine, would, as he should show on another occasion, support the life of a fish longer than the water altogether destitute of oxygen. In respect to ozone, he had no doubt that such a substance

... d, and he was inclined to think that it was a modification of oxygen. He thought that in testing the effects of the peroxide of hydrogen, it were best to try it in disease without any further interrnecliation, selecting for its trial extreme diseases, such as were not at this time amenable to treatment. The actions, physiologically, of the peroxide of hydrogen and of the permanganates were entirely different: the latter injected into the veins of a, horse produced permanent fluidity of blood, and transformed the blood on the arterial side to the venous colour. The difference depended on the fact that in the permanganate the oxygen was combined, while in the peroxide it might be I considered as virtualiy free. Dr. Garrod, Dr. Radcliffe, and several other Fellows, observed that they should be anxious to give the peroxide a fair trial as to its therapeutical value; and inquiry was made as to the means of obtaining the solution.* ° Reviews and Notices of Books.
