I shall limit my remarks to Appendix E. The general tenor of comments, as follows. including my own, run about The impression one would derive from reading Appendix E is at variance with what we feel should be given, and actually we disagree with quite a number of the statements made. I doubt that the book by P. Alexander is the best place from which to extract this type of information. Our knowledge of effects of radiation is much more precise than that indicated in the writeup. et A few examples might suffice. On page 2 it is stated that antibiotics do not increase the resistance of the animals toa lethal dose of radiation. It has been clearly demonstrated in the mouse that antibiotics alone very substantially increase the LDs 9. and we have shown in dogs that antibiotics combined with platelet transfusions very significantly increase the dose level at which animals can still survive. On page 3 the impression is given that we do not know the chain of events leading to death. While there certainly is more to be learned, we do have a very good idea of the chain of events leading to death... On page 7 it says that the outcome is almost entirely dependent upon the make~up of the individual and there is little opportunity for the physician to influence the course of the illness. I think this gives a completely inaccurate impression, since there is a great deal the physician can do to influence the course of the disease. The statements in the last paragraph on the page simply are not consistent with the fact, as are the statements in the first full paragraph on page 10. I can give a number of other examples 9923
