 It is also the intention of the Council to 

 have four meetings during the coming sea- 

 son ; three of them to be held at the Hotel 

 Waldorf and one at the Museum of Natural 

 History. At the meetings held at the Hotel 

 Waldorf the members of the Societj' will be 

 entertained after the reading of the paper.

Recent Researches on the Spectra of the Planets, 



II.: H. C. VOGEL. 



A summary of recent work on Jupiter, 

 Saturn and Uranus. Photographic obser- 

 vations reveal no deviation in their spectra 

 from that of the sun, but in the less re- 

 frangible region bands due to the absorp- 

 tion in the atmospheres of the planets have 

 been recorded visually. A comparison of 

 the visual spectrum of Uranus as mapped 

 by Keeler and by Vogel shows httle varia- 

 tion. Repeated observations on the red 

 spot of Jupiter indicate no difference be- 

 tween its spectrum and that of the belts. 

 From a study of the red region, the satel- 

 lites probably have atmospheres similar to 

 that of the primary. The spectra of Sat- 

 urn and the ansoe of the ring on each side 

 are identical in the more refrangible por- 

 tion. That there is no absorption band at 

 X 618 fiji indicates the absence of an at- 

 mosphere around the rings. 

 On the Periodic Changes of the Variable Star 

 Z Herculis : N. C. Duner. 

 After discussing various observations 

 upon this variable and giving its ephemeris, 

 the writer concludes that Z Herculis is a 

 connecting link between the algol and the 

 T Cygni types, differing ii-om algol in hav- 

 ing both components bright, and from ]' 

 Cygni in that the components are of un- 

 equal brightness. It consists of two stars 

 of equal size, one of which is twice as 

 bright as the other. The stars revolve in 

 3 days, 23 hours, 48 minutes, 30 seconds, 

 in an elliptical orbit whose semi-major axis 

 is six times the diameter of the stars. The 

 plane of the orbit passes thi-ough the sun.
