SOME OF THE MARKINGS ON JUPITER. 6 1 



seen, and attracts attention. Herr Leo Brenner's beautiful 

 drawings show several of these strange markings. 



In addition to these markings, curved ones are occasion- 

 ally seen at a considerable angle to the equator, as if, by 

 some strange convulsion in the Jovian atmosphere, portions of 

 belts were wrenched off, possibly by revulsion, rather than 

 attraction of other parts. Some ten years since I saw such 

 a singular phenomenon in the southern portion of the planet. 



We close by a few remarks on the colour of the belts and 

 markings, and on this subject records materially differ, being 

 largely influenced by personal equation, colour appreciation 

 being a very varied faculty, especially in the light tints of stars 

 and planets. So I venture to give my own observations only. 

 The entire surface of Jupiter appears to me of a light straw 

 colour, intensifying in the portions north of the equator some- 

 times, as at present, to a light amber. The South Equatorial 

 belt is generally of an ashy chocolate colour ; the north nearly 

 the same, with a dash of green of varying intensity. The other 

 belts are of an olive tint, varying to light brown. The red spot 

 is now of a very light grey. The dark spots vary much from a 

 rich brown to nearly black black probably by contrast. The 

 light spots are sometimes of pearly white. In this matter of 

 colour my observations vary very much from acknowledged 

 authorities. For instance, I have never been able to perceive 

 the pinkish hue so beautifully shown in Herr Brenner's drawings. 



Ladies excel us in colour appreciation. I have sometimes 

 wished they would form a committee to give united opinion on 

 this subject, including star colours. 



DESCRIPTION OF JUPITER DRAWING. 



As the drawing was taken in an astronomical inverting 

 refractor, it should be remembered that the south is at the top 

 and the north at the bottom ot the drawing, that the east is to the 

 right and the west to the left of the drawing, thus inverting and 

 reversing all the surface marking. The two principal belts are 

 the South and North Equatorial. The south belt at the date of
