3521DEMAGNETE.

Verum præterea ſumſi duos alios Magnetes, qui ambo erant for-
mæ parallelepipedi, quorum unum ex Libra GX ſuspendebam, al-
terum menſæ TT imponebam, obſervando quantum fieri poteſt,
ut ambæ polares plagæ ſibi mutuo reſponderent in eadem linea ad ho-
rizontem perpendiculari: Magnitudo unius Magnetis erat hæc; longi-
tudo 2 {3/4} pollic. latitudo 2 {1/2} pollic. altitudo 1 {1/2} pollic. alter hujus Ma-
gnitudinis erat, altitudinis 2 poll, longitudinis 2 {1/2} latitudinis 1 {7/12} poll.
