Dear Miss 0straat,
Please, find under separate
cover the graphs of ny paper on long term,:^l
elasticities. I don't know xvhether you inleen
to have them multiplied. It does not quite
seem necessary to me. If you do not multiply
them,can I get them back from you at one
of my lectures in order to demonstrate them?
May I thank you very heartily for the railway tickets and all the
trouble you gave yourself about them ?
Yours -^ery sincerely,
