Abstract
VARIABLE STARS OF SHORT PERIOD.—Prof. E. C. Pickering directs attention to some similarities and peculiarities in the formulae representing the light variations of the typical short-period variable stars (Circular 190, Harvard College Observatory), not only affording criteria for purposes of classification, but also indicating structural features. It is found that β Lyræ. should be regarded as intermediate be tween the Algol eclipse variables and the δ Cephei stars—exactly the order, it may be added, demanded by Sir Norman Lockyer's meteoritic hypothesis.
