A preliminary investigation has been made of the crystallographic data of 4-methyl-5-ethyluracil (I), 4-methyluracil-5-acetic acid (II), 4-methyl-5-methylaminouracil (III), and 1-phenyLhydantoin (IV). The lattice constants and space-group data were obtained from rotation and Weissenberg photographs; the determinations were made on the basis of one crystal setting for each species, and the measurements were corrected for film shrinkage. The angular constants of the direct cells were determined by the method of angular lag (Buerger, 1942): from measurements on (1) an equi-inclination photograph of the first layer in monoclinic cases, (2) a composite anti-equi-inclination photograph (of the zero and first layers, respectively) in triclinic cases. The crystal densities were determined by flotation. The errors are estimated to be about ± 0.05 Å for the linear constants and about ± 0 ° 20' for the angular constants.
