INSTITUTO DE QUIMICA FISIOLOGICA Y PATOLOGICA ESCUELA DE MEDICINA UNIVERSIDAD DE CHILE December 6, 1956 Borgofio 1470 - Santiago . Dear Joshs I received your letter of November 21 together with a letter of Berrie Davis in which he says that he will be glad to have me in his lab. T must thank you and congratulate you for your efficiency. I was very touched by the feeling of being supported in this situation. Luckily Raquel is feeling a little better and we have cancelled our reservation because the doctor who takes care of her here in Chile convinced her to postpone the operation for at least a month or two. Let's hope that she will continue improving and the trip to the States will be planned under happier circumstances. Your letter of November 19 arrived a few days later than the one of the 21st. You can see that the Chilean Post Office is very reliable, I was sure it was lost. The S’ mutant has not arrived yet. TI am trying again to get one myself. What concentration of streptomycin do you use in the EMS? TI have searched all your . papers I have without finding the datum, finally I am using 50 mg per liter, This figure was taken fror m Bertani's paper. Raquelita asked me to ask you about a wedding gift for Ruth Zloten which was sent c/o your address. Did you get it? Another question, this time ny owns I have to decide between a microscope Leitz (Ortholux or Dialux) or a Zeiss. ‘Which one would you recommend? , The U. of Chile has approved the investment of a few: millions to fix me a lab. It will take a couple of months to finish it. It was an important step because the School of Medicine is building a brand new School to be finished in about five years, therefore they are against any expenditure in this old building we are now. The Director of the School of Medicine was very enthusiastic about a project of mine to solve rapidly the shortage of scientists in Chile. I proposed that the University should offer a snecial course which will consist of four years of studies in Chile (after finifhing High School) and about three years in a good Univer- sity of the U.S. to obtain a Ph. D. During the studies in Chile the student's adviser should decide about the courses which the student takes in the different departments of the University. Right now there is no way of getting a degree in Chile aside of the applied ones; M.D., engineer, dentist, pharmacist, etc. I have started already my plan by sending a young bo in the fourth year of Medtcal School to Sol and an associate of mine to Pollock. , Thanking You Wholeheartedly, with best regards, Pew
