Abstract
On the plates taken with the 26-inch McCormick visual refractor and with the 26-inch Yale Southern Station photographic refractor the relative positions of 366 Long-period variable stars have been measured and their relative proper motions derived. For 22 variables both McCormick and Yale plates were available and the motions were derived in duplicate. They served for combining the results.
