A rectangular substructure or superelement is described for use in the vibrational analysis of plates and flat plate assemblies. Basic features include elimination of internal nodes and flexibility in the location of nodes along the boundaries. Illustrative examples demonstrate the efficient and versatile application of the element. The main focus, however, is on solution accuracy for different representations of mass. In particular, it is found that the homogeneous inertia properties of a plate must be expressed by a consistent substructure mass matrix in order to model dynamic properties accurately.

Crystallographic studies of rabbit Fc using X-ray diffraction patterns were recently reported. The unit cell constants were reported to be a = 69. 2 A°, b = 73. 1 A°, c = 60. 6 A°, B = 104° 30', space group P21, monoclinic, volume of asymmetric unit V = 148, 000 A°3. The molecular weight of the fragment was determined to be 55, 000 ± 2000 which is in agreement with earlier determinations by other methods.Fc crystals were formed in water or dilute phosphate buffer at neutral pH. The resulting crystal was a flat plate as previously described. Preparations of small crystals were negatively stained by mixing the suspension with equal volumes of 2% silicotungstate at neutral pH. A drop of the mixture was placed on a carbon coated grid and allowed to stand for a few minutes. The excess liquid was removed and the grid was immediately put in the microscope.
