X-RAY DIFFRACTION PATTERN OF NERVE MYELIN: A METHOD FOR DETERMINING THE PHASES.
The x-ray diffraction patterns of normal myelin, and of myelin expanded by soaking in hypotonic solutions, have been compared quantitatively. Application of the "shrinkage stage" method for determining the course of a real Fourier transform allows all but 2 of the 32 possible sign combinations to be eliminated.

The fine structure of some retinal photoreceptors.
An electron microscope study has been made of octopus and amphibian photoreceptors, after fixing with KMnO(4) and embedding in araldite. What has previously been seen as a single dense stratum bounding the tubular compartments (octopus) or the double membrane discs (rods and cones), now shows a double structure. We interpret this as showing that these tubules and discs have similar bounding surfaces, which are probably directly related to the cell membrane. This is confirmed by the finding that the tubules and discs are (at least occasionally) continuous with the cell membrane.
