Mr. Pound obServed a fmilar eclipfe at VVan- Read, jui two Sarotic periods before this, and has iScnbed it m the PhiloJ: EranJ: N. 347, p 4024 and makes the following remark, " Thls ecllpfe iS ' tte more coIifiderable, as happening very netr 4' the moon's perigg and therefore uSe-ful to rerify " her anomaly; as algO to limit the greatefl: diameter ' of the {hadow of the -earth, and conSequently the " parallax of the moon. This may be very properly " compared with that of the Igth Qf Odobu 6g7> +' wholie middle-was at 7h It p. m. at London, and " the qualltlty the me as now*"
