Fig. 2. 



Diagram of stars in the Pleiades, as seen in an inverting telescope. The portion of 

 the film distorted is shown by the shaded portion. 



I now proceed to give the details of the individual measures of the 

 six stars which present the anomaly in question, and contiguous to 

 them will be found the accordances of the similar measures on the 

 three other plates.
