Typescript of Crick, "The strength of the 10Å reflexions in haemoglobin," as returned with editorial marks, following acceptance for publication in Acta Crystallographica , 6 (1953), 600-3. A copy of the letter (13 February, 1953) from Crick accompanying the submitted paper is also included.

The file includes two sets of notes and calculations (holograph), one beginning: "The following ideas arose while I was thinking about the shape of haemoglobin. I was considering a unit cell made up of bodies of constant electron density embedded in a sea of a constant, but different, electron density. I wondered whether there was any mathematical expression which was related to the total surface area of the bodies. I have been able to show, very crudely, that the total surface area is proportional to a weighted sum of the intensities...."
