ELASTICIS. 301 Hinc intelligitur verum valorem ipsius $Φ$ non intra istos limites contineri, sed aliquantulum esse minorem quam $1°, 0', 40"$. Nihilo vero minus is ex his erroribus reperietur. Sit enim $Φ = 1°, 0', 40" - n"$; erit $20" : 52509233 = n" : 6363418$ unde reperitur $n = 2423/10000$, ita ut fit $Φ = 1°, 0', 39 7576"/10000$. Cum ergo fit $Φ = 3639,7576"$ erit $lΦ = 3,5610724615$ subtr. $5,3144251332$ $8,2466473283$ $Φ = 0,0176460428$ $a/π = 4,7123889804$ $a/c = 4,7300350232$. 86. Sit hic numerus $a/c = m$, erit, ob $c* = (Ekk.af)/M$, $a* = M/(m⁴.E [TRUNCATED]
