that he is enabled to represent all the rates very nearly by the formula: 
865 — 165’ sin = Jat. 
Consequently the sidereal rotation of the equatorial photosphere is ac- 
complished in 30°86 days, and of that at a latitude of 50° N. or S—the 
question. Mr. Carrington considers that the views of Professor Thomson 
tudes, and easterly in the higher latitudes; the direction of rotation in 
such cases being t i
