I will give a short history of my goings on since I saw you in 1971. Helen and I were off the first semester taking a trip around the world. I thoroughly enjoyed myself as did she but I guess I rather overdid it. We went to a meeting in Australia, spent a month on that continent, then India, then Africa, of which my son is married to an English girl who comes from South Africa, We then went up through Europe and finally home, altogether spending months. I felt a little tired after the trip but thoroughly enjoyed it. I had the article in the Annual Review to write and starting in January I proceeded to get this out. On March 22 I read the proof of this article, finished up my course I gave to pharmacy students, and promptly passed out completely. The trouble was in that I had a stroke. I was laid up for four months in the hospital and came along rather slowly after that. Finally, the first of February we went to spend the winter season in Texas and before long I was sitting up till midnight listening to the television and thoroughly enjoying myself. I have improved a great deal since that time and retired in 1973. I was 70 years old at that time. I gather that you did not know of this matter. Now to get down to the business of this letter, I am endeavoring to get some information and have been promised some from Dr. Brink, and as soon as I can see him I will write you further, In the meantime, I was glad to hear from you. I had heard a rumor that you had a young daughter and I am delighted to have it confirmed. 3 hove, OST) Unfortimately, I hadn't heard of this paper by Cole and Wright but Wright died in early 1928, I believe. It was very tragic that he should die at this time. He just keeled over with a bad heart or something. I knew him fairly well as I had taken two courses in Bacteriology from him. Sincerely, “Pure Wo.
