I7. Viol in his work on excretion found that 35 to 40 per cent of the radium injected in- travenously was excreted in ten days and there after the excretion rate was around I per sentp per month He based his observations on an examination of the excreta. Wada in- jected 25 and I000 M U doses of radium into a series of rabbits and at the end of four mnoths he wag unable to detect any radium in the organs of the rabbit getting the 25 M U dose. - the case of the IOOO M U he found radium in the bones and the amount found bore a relationship to the amount injected. He has made an interesting observation that may have aome bearing on our problem. He feels that in order to get a stimulating effect it is better to inject a large quantity at once as the part not eliminated at the begimning is stored in the bones and thus furmishes the blood with a steady stream of emanations. On the other hand small doses given repeatedly act# on all the cella of the body and among them the blood forming cella and this repeated stimulation is ob- viously too strong. Our experiments bear out Viol to a certain extent. We injected an equal amonut Of radium into a number of piga and killed them off at stated periods, burming them to an ash and making a radium deternimation. This XEPE experiment is still being contimued and will be reported at an early date. Some of our findings are: Amimal killed I5 minutes after injestion 4.21 micro grams 24 hours 3.73 48 2 3.15 7 days I.32 I4 " I.29 Gudzent states that quantities of .00I mg of radium equivalent increases the vital functions while amoumts of .25 imhibit them. Both he and Beck feol that the effects are not due to the radium itself but to the emanations. Beck discusses a toxema the re- Altri brought don't by sult of the by-products which result from their actions on the cellular structure. Due to the iomizing action of radium probably many of its effects physical chemical changes. The observations by Chamber and Russ indicate that the red cell: of the human blood are hemolyzed much more sasily by the alpha rays than by the beta and gamma rays.
