The beryllium content of 73 stony and 4 iron meteorites has been determined 'non-destructively' by a newly developed sensitive low-level counting device. A fairly widespread beryllium content of stones ranging from 13 to 386 ppb was found. As expected from the lithophilic character of Be the 4 siderites contained less than 8 ppb only. The resulting average chondritic abundance of 74 ppb Be is more than one order of magnitude lower than the cosmic abundance value adopted earlier by H. E. Suess and H. C. Urey (1956), but still about a factor of 2 higher than the value chosen by A. G. W. Cameron (1968). 10-15-g samples were taken in order to guarantee a rather good 'mean'. For comparison the Be content of the U.S. Geological Survey basalt BCR-1 was determined in the same way to be 1.390 plus or minus 0.006 ppm Be.
