FEDERAL SECURITY AGENCY U.S, PUBLIC HEALTH SERVICE IN REPLYING, ADDRESS THE The. Research Laberatory, 411 E. 69th St., New Yerk 21, N. Y. Nevember 10, 1948. Dr. Joshua Lederberg, Department ef Genetics, The University ef Wiscensin, Cellege ef Agriculture, Madisen 6, Wiscensin. SRE me | Vvee eho Yeur reply frem the editers ef the JBC is certainly surprising. I have not yet heard frem them, but will undeubtedly receive the same treatment. My first impulse was te write them immediately requesting withdrawal ef my letter and te send mine te the Jeurnal ef Bactericlegy as you suggest. I agree with you that a pair of netes side by side in this jeurnal would solve the preblem. On further censideration it seemed te me, hewever, that this is such an idietie decision en the part ef the . JBC that it would be better te see if something may net yet be dene with mF them. Dr. DuVigneaud here is quite interested in this werk and is an oe editer ef the JBC. I sheuld therefere like te wait fer twe more events befere sending my nete te the Journal of Bacterielegy. The first ef these weuld be te make sure that the JBC might not pessibly recensider your letter when the editer has feund that beth of us censider this a significant enough matter fer simultaneous publicatien. The secend weuld be te see whether Dr, DuVigneaud might net be willing te intervene with his jeurnal. Dr. DuVigneaud is unfortunately out of tem and will not be back until Saturday er Menday. I hepe you will not mind the extra delay ef a few mere days, because it really seems te me werthwhile te try te get this befere a biechemical audience, Incidentally, I have not yet finished pelishing up the lenger manuscript, which I do hepe te get eff te the PNAS within a few mere days. As te the nete te "Nature", I had ne intention at all ef sending that as well as a letter te an American journal. If you would prefer te send your letter eff te the Journal ef Bacteriology at this time I could have ne ebjection, but it weuld seem te me very much preferable to wait another week er twe if necessary te see whether we cannet get them published simultaneously in the JBC; if that dees not werk I weuld then send it te the Journal ef Bacterielegy. Sincerely yours, 77 , C7 orecee ( Bernard D. Davis, BDD/h1 _ Surgeen.
