excellent judgment with which they appear to have been put together, there is every reason to suppose it would have withstood the ravages of time, for succeeding generations to behold, with admiration and astonishment for yet many ages.

If the first observation by Capella be rejected, the mean of the remaining seven will be 89 2' 32".

THE observations were made with a fine Sextant by Troughton, and Artificial Horizon. The refractions applied in computing these, and all the following observations, were taken from Monsieur Le Gentil's Table, published in his " Voyage dans les Mers de L'Inde."

The declinations of the Stars were taken from Table 7th of the Requisite Tables, and partly from Dunn's Catalogue.

AN excellent Chronometer by Arnold was used in observing the time; to correct which, frequent
observations of the sun and stars were taken. The former by equal or corresponding altitudes, ob-
served before and after noon, to which the proper equations were applied; and in the latter case by
taking several altitudes of a star east, and one west, a few minutes before and after the observation,
these were calculated separately, and the mean of the results was applied to the correction of the
watch. The apparent time, as deduced from the sun or stars, agreed in general within a second or two.
