1. The mesoglea of the marine sponge, S. graminea, resembles in its organization and composition the connective tissue of vertebrates in that it is composed of collagen fibers and fibrils embedded in an amorphous matrix containing carbohydrates. 2. Two morphologically distinct forms of spongin fibers, designated spong…
The kinetic theory of melting and freezing is developed from consideration of atom movements at an interface between solid and liquid. The equations developed are shown to have the same form as the corresponding thermodynamic equations. The homogeneous nucleation of a solid phase in a liquid is then considered from th…
A complete treatment is given of the steady state spiral both in growth and evaporation of crystals, taking account of the strain energy around the dislocation. It is shown that when the crystal is evaporating there is a limiting value of the undersaturation beyond which there is no steady state solution of the proble…

Above the Curie temperature, pyroelectric currents can be produced in single crystals of barium titanate even though there is no electric field applied. The polarization that remains at these temperatures is ascribed to space-charge fields in the crystal. From studies of the wave forms of the pyroelectric current sign…
Abstract Measurements have been made of the intensities of up to 25 orders of the low-angle X-ray diffraction patterns of wet and dry collagen fibres from three different sources. From these data Patterson functions have been plotted, and using these curves, and the known results of electron microscopy as guides in ma…
With the aim of determining to what extent the energy distribution of secondary electrons from targets of Mo and W may contain fine structure, measurements have been made using primary energies from 100 to 2000 electron volts. An electrostatic analyzer of the 127-degree type having an experimentally determined resolut…
