The nuclear magnetic dipole moment of 151 Eu and the ratio of the moments of 151 Eu and 153 Eu have been measured by the new method of resonance in three loops in a short atomic beam. The results are: μ ( 151 Eu) = 3·419 ± 0·004 n.m.; μ ( 151 Eu) / μ ( 153 Eu)= 2·2686 ± 0·0015. The result, taken together with the ratio of the hyperfine structures of europium, gives a hyperfine structure anomaly of (1·0 + 0·23)%. A theoretical value of the anomaly is estimated.

Specific Orientation

Investigations which require electron microscope examination of a few specific areas of non-homogeneous tissues make random sampling of small blocks an inefficient and unrewarding procedure. Therefore, several investigators have devised methods which allow obtaining sample blocks for electron microscopy from region of tissue previously identified by light microscopy of present here techniques which make possible: 1) sampling tissue for electron microscopy from selected areas previously identified by light microscopy of relatively large pieces of tissue; 2) dehydration and embedding large numbers of individually identified blocks while keeping each one separate; 3) a new method of maintaining specific orientation of blocks during embedding; 4) special light microscopic staining or fluorescent procedures and electron microscopy on immediately adjacent small areas of tissue.
