Demerec ‘Department of Genetics i Carnegie Institution of Washington ‘Cold Spring Harbor,L-I. ‘New York ‘Dear Dr. Demerec? I sent you this morning by first class mail the manu- 'seript "Recent Advances in the Genetics of the Ciliated Proto- 'goa", Please drop me a card when you receive it for 1 am worried | about .the possibliity of its getting lest in the Christmas rush. i You will not be likely to guess the amount of labor I put ‘into that job. I have worked on it steadily since August,putting everything else aside,sven to an unfortunate extent ,my research. But it was a job that seemed to me well worth doing and I have | profitted greatly by it myself,seeing more clearly the relation lof my omm work to the rest of the work in the field. | | As you see,I have taken up your kind offer to let me have | more than the original limit of 50 printed pages. At your fige | ure of 500 words per page,the body of the paper will run about | 60 pages,with extra for figures,tables,bibliography and table 'of contents. If the paper as it now stands 1s too long,the only ‘way I could cut it would be to eliminate the treatment of one or more of the species. If that is done,it will of course mean at least a complete rechecking of the bibiiography,pulling out titles and renumbering all that remain,with corresponding cor- rection of the numbered references throughout the text. I should certainly not welcome that job,but I will of course do it if ‘you say so. I hope I have written the sort of thing you had in mind for me to doe And now I owe you &n apology for mot answering sooner your Letter about the conference on mtations. But you can see from this negligence the way I have consistently neglected everything in order to got my manuscript to you as soon as possible. I have ' before me a stack of unanswered letters and other business that has been accumulating for © month while I devoted myself on ths average of 10 to 12 hours a day to the manuscript to the exclu- ston of everything else. Your letter is the first I take up to answere I wanted to think it over to see 1f I might really have | gomething to contribute before accepting. I am still a little vague about the whole thing,as I never attended any of the gene conferences to which yo refer,but nevertheless I do want to attend and accent your kind invitation to act as chairman of the section on "Extranuclear factors". I should greatly _ appreciate 1t 4f you would inform me in more detail what I am expected to do in the introductory statement and how I am to eonduct the discussions. Also,what hour and date 1s set for the first session,so I can arrange to be there on time. —
