Address should read: Dr. H . Brieger , Professor of Industrial Medicine and Director of the Division Division of Industrial Medicine Department of Preventive Medicine The Jefferson Medi,cal College of Philadelphia 10 2p Walnut Street, Philadelphia', Penn. July 11, 1958 Dr. Heinrich Brieger, professor of Industrial Medicine Department of Pediatrics and Preventive Medicine Jefferson Medical. College; of Philadelphia 102p Walnut Street Philadelphia, "Pennsylvania Dear Briegers In reading the paper of Robinson et al published in the May issue of Pediatrics (1958) I was surprised, in con nection with the discussion of the normal range of the lead concentrt ion in the blood and the partition of lead between erythrocytes and plasma, to find no referenceto the extensive work of this Laboratory on both matters. I -am not finding fault wit h the discussion and references from the asoect of credit, but rather from that of the failure of the primary author to call attention to pre viously established facts. It would seem that the avail able evidence as to the normal range of values in the adult (unfortunately we have published little of our more recent information on the child) should have included our data as a trustworthy source of information. It Is true, of course, that we have worked much and published sparingly, but I should have thought that Robinson would have seen Sambach's paper on "The Plasma - Cell Partition of Blood Lead", with Its extensive investigation of the behavior of lead In the blood of rabbits, and 'its slight but relevant data on the blood of adult men. Perhaps he regarded the latter too slight In evidence as to human blood for reference, but this was inserted only to show that the same situation so thoroughly investigated In the rabbit had application, in all likelihood,to man in view of the citation of the evidence on human blood already obtained, examples of which had been published (Kehoe, Chblak and Story. J. Nutrition, 19: 579>19ii-0). The latter* article ra^ht well have escaped Robinson's attention, buthit has been referred to in several of our publications in more readily available journals, as in "Experimental Studies on the Ingestion of Lead Compounds J. .H.and T, 22: !|00 (Bibliography' 19^0. I call this to your attention, rather than to Robinson's, out of courtesy, since I take it that be is associated with you, and that you would wish to call these matters to his attention, as his senior, in view of your own care to know what is in the K r 0019980 Dr. Heinrich Bri e gar - (2)- July 11, '\ \ literature on a subject which you undertake to discuss. This is not to suggest that the work reported in this article is not first-class or pertinent, in itself, in considering th-i.se matt era in relation to children. More over, I ras pleased to not the reference to the pioneer ing 'and precise work of Willoughby on the lead in blood, especially because it is so often omitted in the references of otters on this subject. Sincerely yours, RAKkss Robe rt "A '&Q hoe /"m ,D KC 0019981
