NEW JERSEY 07430 T& 20J-S29-3450 TELEX- 01-33335 March 11, 19^9 Mr. C. H* Borcherding, Jr* Medical Department Chicago Dear Charlie: Thank you for your letter of February ?7, stating that gas sampling time will be approximately 16 minutes per shoe. We would suggest that instead of running 30 second stops, we run ?0 minute drag teste (simulating grade braking) in which the sampling could be for the laet l6 minutes of each drag. This would allow t minutes for the shoe and wheel to heat up and start smoking. Bob Ely is arranging for the X-ray defraction analysis which you suggested by done by Research at Mahwah. We have just received the Cobra and Anchor shoes from San Francisco and now have the necessary shoes. However, the dynamometer will not be available until April 1^ or as soon thereafter as you can make it. If you will confirm a date, we will finalize the dynamometer scheduling. ERKtez cc - R. J.
