March 18, 1932 Dr. M. M. Shafer, Frigidaire Corporation, Dayton, Ohio. - Dear Dr. Shafer: a The blood smears on Mr. check No. 226-079, have been examined. The smear shows one stippled cell, which is an entirely insignificant find ing since one or more stippled cells are commonly found in normal blood. I refer to one stippled cell per 50 fields. In lead cases the stippling usually run3 from , twenty or more up to several Hundred per 50 fields. This information is not to be regarded as entire ly diagnostic, though in my opinion lead poisoning with in a comparatively short time after exposure is hardly compatible with the absence oi? stippled cells. A differential white cell count shows Polymorphonuclear .... Lymphocyte ...... Mononuclear ....... Eosinophile........... 43.5 64.5 1. 1. If the exposure of thi^ man has been of recent date, I would suggest the advisability, or In fact the necessity, of examining samples of the faeces and urine In order to determine the extent of lead excretion, which in turn gives a satisfactory measure of the lead absorption. If for any reason you wish to have this done let me know and I will send you the necessary con tainers with instructions for the collection. f Very truly yours, RAK:EJT N6294
