Columbia University,

Dear Sir:

Although I haa plannea to work all summer, I find myself attracted by tne
poscibilities of your Chem s42C course, I shouia not trouble to write you
except that I anticipate some technical difficulties in the manner of satis-

faction of prerequisites. Last January, with Prof. Nelson's permission, I
was able to pass the final exam in Chem 41 as an achievment exam on the bast

of personal self-instruction for several years. I haverhad no other chem
courses in Columbia College, but in high school learned the rudiments of
yguelitative analysis. Ky main interests are in physiologicel cBemistry- for
the last few months I had been working at Columbia on enzyme-inhititors and
sneir errect on mitosis in the onion root-tip- so tnat my laboratory experi-
ence in Chem 41 material may not be quite up to par. I have prepared a few
compounds,however- acetaldehyde, methyl orange, Magneson I (dinitrobenzene-
azoresorcinol) and other simple preps. However,I plan to spend some evenings
this month brushing up on tnat technique at a very weli-equppped home lab of
ea friend. Under these circumstances,do you anticipate any daitriculty in ac-
cepting me into your course, Chems42C with creait for the Goliege? Prelimina
ry remarks ty my coliege adviser indicate no aifiiculty there.

Sincerely yours,
