Measurements have been made of the electrical resistivity of two single crystals of beryllium parallel and perpendicular to the hexagonal c axis, respectively, between 4 and 800$sup 0$K. The resistance ratios were 10.0 and 15.5 for the parallel and perpendicular directions, respectively. The anisotropy of the temperature-dependent part of the resistivity was about 35% (rho/sub i// sub parallel/ being higher) at room temperature in contrast to 12% found by Gruneisen and Erfling. The anisotropy was approximately constant in temperature above 273$sup 0$K and decreased rapidly below. The Bloch-Gruneisen equation was fit to the data. The characteristic temperatures were theta/sub R/=1246 +- 1 and 1202 +- 1$sup 0$K for the parallel and perpendicular directions, respectively. (AIP)
