Buache, its geographic afib- ciatc< rMYSICS. • AMONG the great variety of objedls which the (ludy of phyfics comprehends, it is peculiarly in- cumbent on the navigators to dired their atten- tion to fuch as are governed by a regular caufe, but the intenfity of which is neverthclefs fubjcd to variations, which can only be determined by conne<5lecl and multiplied obfervations. Of this nature is the variation of the compafs. Obfervations on the variations of the needle making a principal part of the means of diredion, which will be employed by the navigators, the academy, on this head, judges it fufficient to re* commend to them to obferve, by the help of the accurate inftruments with which they will be fur- niflied, the diurnal variations of the needle, while they make any flay on land. It has been difcovered by fome obfervations firft made at Breft, at Cadiz, at Teneriffe, and at Goree, on the coaft of Africa, and afterwards at Bred,.
