KNOWLEDGE. 



[October 1, 1894. 



supposes Jupiter to be passing through a carboniferous 

 or Devonian period, such as existed on our earth, but 

 neither the pictures nor the text exhibit much geological 

 knowledge, and his knowledge of astronomical facts is still 

 more meagre.

ORBIT OF y ANDKOIIED-E. 

 To the Editor of Knowledge. 



Deak Mr. Eanyard, — Barnard has this year 



sot a set of measures of 7 Andromedre with the thirty-six 

 inch. I have put his last position on my original diagram 

 of the apparent orbit, and enclose a photograph of it. As 

 you will see, Barnard's place tits in beautifully with the 

 ellipse already indicated. Yours very truly, 



S. W. Bdenham.

THE LEONID MAXIMUM. 

 To the Editor of Knowledge- 

 Sir,— I think the answer to the question asked by 

 Mr. A. CoUison, on page 185, has not been fully given. 

 What he really wishes to know is the time that the 

 maximum of the shower will take place. The earth will 

 be in the same longitude, 1899, November 13th, 13h., as 

 it was in 1860, November 13th, 13h. 9m., when the shower 

 reached its maximum that year ; but does not the time of 

 maximum alter from year to year '? I suppose it will be 

 possible to make a better forecast nearer the time. Is not 

 1900 just as likely as 1899 for the greatest shower '? 



Yours respectfully.
