Thanks! I went ahead and created an account and requested the text from him but I doubt I'll get a response.

This paper was originally published in 1966. You might be waiting on a response from the author from the Great Beyond.

Update: checked the McMaster U website. Prof Rosa is listed as Prof. emeritus:

Thanks! I took a risk and sent him an email.
 
I have always wondered what internet provider the "great beyond" used!
 
It must have been fancy shmancy because I got a response rather quickly.
