Dear Dwight:
You can get pieces of glass coated with aluminum in various places. I am sure that this work can be done in the Physics Department at Ithaca, and that by speaking to Professor Gibbs you could make arrangements for getting your mirrors. I believe that I saw a report on work of this sort at Ithaca in one of the recent physics journals. Moreover, Badger tells me that commercial firms advertise this service in the Scientific American. If for some reason these sources were unsatisfactory to you, you might be able to get Dr. John Strong of this Institute to do the work for you. He is the man who puts the aluminum coatings upon the big telescope mirrors here, and who prepared Badger's mirrors. I haven't seen him recently and Badger says that he may not have his set-up for small mirrors working now, but if you want you might write directly to Strong.
I am glad to learn that your new protein work looks
promising.
With best regards, I am
Sincerely yours,
LP/jr
