Dear Sir:

Although I had piannea to work all summer, I find myself attracted tq tne

possibilities of your Chem s42C oourse. I shoula not trouble to write you

except that I anticipate some technical diffioultics in the manner of satis-

faotion of prerequisites. Last January, with Prof. h'elson's permission, I

was able to pass the final exam In Chem 41 as an achievment exam on the bask

of personal self-instruotion for several years. I havechad no other ohem

courses in Columbia College, but in high school b3arned the rudiments of

qulitative analysis. Ky main interests are in physiological cln'emistry- for

the last few months I had been working at Columbia on enzyme-inhibitor8 and

2Eeir efrect 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, Dilagneson I (dinitrohenzene-

azoresoroinol) and other simple preps. However,1 plan to spend Borne evenings

this month brushing up on tnat technique at a very well-equ$pped home lab Of

a friend. Under these oircumstanoes,do you anticipate any diffioulty in ao-

cepting me into your course, Chem42C with credit for the Coliega? Prelimina

ry remarks by my oollege adviser indicate no difi'iculty there.

                                Sinoerely yours,
