TABLE I.— Continued. 



information desired. It is thought best not to delay the publication 

 of the present circular in order to obtain additional information, much 

 of which must be procured from Europe ; but astronomers will confer 

 a favor upon this Observatory by sending material which may be used 

 next year to malie the table for 1883 more complete. It is highly 

 desirable that this information, as well as that respecting the observa- 

 tions of 1884, should reach this Observatory as early as February 1, 

 1885, in order that the proposed circular may be issued as early in the 

 year as possible. Information received later, however, may be made 

 serviceable in any circular which may afterwards be prepared. 



The bibliography undertaken by Mr. Chandler, as above mentioned, 

 will eventually furnish the means of preparing a catalogue of all the 

 stars now known to be variable. The list in Table I. is from his 

 provisional catalogue of known variables, which consists of Schonfeld's 

 Second Catalogue,* with forty-eight additional stars whose variability 

 seems certain.
