对梅恩和斯通先生出版的星表中所有恒星的自行进行了仔细的研究（《皇家天文学会回忆录》，第二卷）。二十八.和xxxiii.）让我得出了一个有趣的结论我发现，在天空的某些部分，星星表现出明显的向一个确定的方向漂移的趋势。在自行星表中，由于恒星的排列方式，这种趋势被掩盖了;但是当自行在地图上显示时，通过在每颗星星上附加一个小箭头，其长度和方向指示星星自行的大小和方向，恒星漂移（这种现象可以被称为）变得非常明显。这是值得注意的是，麦德勒，已导致某些考虑，以审查附近的昴星团的痕迹，一个社会的自行车，建立在漂移，他实际上发现在金牛座他著名的理论，即Alcyone（明亮的昴星团）是共同的中心周围的恒星系统正在移动。但实际上，金牛座的运动共同体只是一个单一的例子，而不是可能指出的最引人注目的一个特征，在天空的许多地区都可以认识到。在双子座，有一个更引人注目的东南方向的漂移，金牛座的漂移是向西南方向。在狮子座也有一个明显的漂移，在这种情况下，对癌症。
A careful examination of the proper motions of all the fixed stars in the catalogues published by Messrs. Main and Stone (Memoirs of the Royal Astronomical Society, vols. xxviii. and xxxiii.) has led me to a somewhat interesting result. I find that in parts of the heavens the stars exhibit a well-marked tendency to drift in a definite direction. In the catalogues of proper motions, owing to the way in which the stars are arranged, this tendency is masked; but when the proper motions are indicated in maps, by affixing to each star a small arrow whose length and direction indicate the magnitude and direction of the star’s proper motion, the star-drift (as the phenomenon may be termed) becomes very evident. It is worthy of notice that Mädler, having been led by certain considerations to examine the neighbourhood of the Pleiades for traces of a community of proper motion, founded on the drift he actually found in Taurus his well-known theory that Alcyone (the lucida of the Pleiades) is the common centre around which the sidereal system is moving. But in reality the community of motion in Taurus is only a single instance, and not the most striking that might be pointed out, of a characteristic which may be recognized in many regions of the heavens. In Gemini an there is a much more striking drift towards the south-east, the drift m Taurus being towards the south-west. In the constellation Leo there is also a well-marked drift, in this case towards Cancer.
