III. THE TOTAL SOLAB ECLIPSE OF AUGUST LAST. 



By William Crookes, F.B.S., &c. 



The important observations which were made last year with the 

 spectroscope, polariscope, and photographic camera caused the total 

 solar eclipse which took place on the 7th of August, and was visible 

 over the greater part of North America, to be regarded with more 

 than ordinary interest, as it was anticipated that the few minutes' 

 opportunity then afforded would enable several points left doubtful 

 last year to be satisfactorily cleared up.
