I. Magnetic injiuence of the Violet Ray. — The power of the vio- 

 let portion of die solar spectrum to convert a steel needle into a per- 

 nianent magnet seemed to have been well established bj Prof. Moi'- 

 ichini in 1812, and confirmed by Mrs. Somerville in 1826. But 

 other philosophers having failed to obtain results which diey deemed 

 satisfactory, some doubts appear to have prevailed with respect to die 

 certainty of such an influence in the violet ray. FroL Zantedeschi, 

 of Pavia, m an ardcle communicated to the Bib. Univ. of Geneva, 

 states, that having placed die extremity of a well polished soft iron
