Dear Dr. Carmel s 
Thank you for your prompt response to my inquiry 
of October 26, 1956. I certainly enjoyed what you had 
to say about coral reefs, and I am therefore tempted to 
ask which self-contained diving unit you prefer or per- 
haps would recommend. You speak of several, but what about 
the Scott Hydro-paJc that your artist used? 
Thank you again for that copy of your Mews Letter. 
Sincerely , 
Waldo L. Schmitt 
Head Curator
