Dear Dr. Machle, ' While in Cleveland this past week I had an opportunity of talking to Dr. Bryson regarding Mr.jB BB^condition, Dr. Bryson told me that he has been seeing Mr. ^Unpractically every week and that his condition is much improved. He has gained some weight and has been sleeping very well without the use of any sedative. I also checked with MMrr.. AAp^tbaugh of the Gulf Refining Corporation and he said that Mr. aHwMPp^thad been working very steady and seemed to be will ing to go right ahead with any type of work to which they might assign him. Dr. Bryson said that he would send you a full report on !vir^mpwithin the next couple of weeks. He also asked that he he kindly remembered to you and that any time you are in Cleveland he would appreciate your giving him a call or if the opportunity present ed itself he would like to see you personally. At the Gulf plant another storage t ank was cleaned and it might he interesting to you to knowthat Mr.VHMHHHHh; did this work. The tank in question to the best of Uttohmation 1 could gather had never contained leaded gasoline being used exclusively since 1935 for the storage of third grade gasoline. Mr. Grants from the Toledo Office sent over to Cleveland a Mr. Callahan who, I was given to understand, nowhas complete charge of tank cleaning operations for Gulf in this territory. Mr. Callahan is quite familiar with our requirements and even though the tank which was cleaned!had no history of ever containing leaded gasoline he had Mr. wear the proper clothing and use the airline mask at all times. This was a relatively small tank with very little deposit so that the actual work of clean ing took approximately two hour's. I secured a sample ojf this sludge which I will get down to you within the very near future. Very truly yours, NDS:o N. D. Siebenthaler. ii K r 00178-26
