The influence of increased barometric pressure on man.—No. I

The classical researches of Paul Bert, (1) confirmed in recent years by v. Schrötter (2) and his co-workers, and also by Leonard Hill and J. J. R. Macleod (3 and 4), have demonstrated beyond question that the ill results observed in caisson workers and divers are to be attributed entirely to injudicious rapidity of decompression. Experiments on animals have shown that every 100 c. c. of blood or tissue fluid dissolve, at body temperature, about 1 c. c. under two atmospheres; 3 c. C. under three atmosphere, and so on (Hill and Macleod, Hill and Ham). 5.
