and most deliberate of my lunar series; its want of success may be attributed to two causes: the Eastern Star was the most ineligible, with one exception, of the whole year's category, and the hill-forest below it was on fire.

The record of latitudes needs no comment except in one particular, viz. the rather serious difference from the positions adopted by Lieutenant Garnier between Sü chow and Tungch'uan. I do not know if his results for that section rest upon sextant observations. It may be objected that my latitudes in that part of the route depend upon altitudes taken only upon one side of the zenith, but this stricture will not apply to the station of Chiang-ti, where the discrepancy is equally apparent. At Tung-ch'uan and farther south the agreement is satisfactory. For the position of Tali Fu Mr. Garnier appears to have accepted the Jesuits' latitude; indeed, as he had barely time to escape from personal danger in that neighbourhood, it is not to be supposed that he could have devoted much attention to sextant manipulation.

It will be seen that my latitude observations from No. 48 downwards exhibit a considerable intrinsic sextant error, apart and distinct of course from index error; but, being constant, it was of no importance whatever, and I thought it well to refrain from "tormenting the instrument."

The observations for compass variation (Table G.) were all made by sun's altitude and azimuth, no sunset or sunrise sights being anywhere obtainable.

In Table (H.) I have compared my deduced positions of the most important points with the determinations of the Jesuits and of Mr. Garnier. The latter have been measured from his general map, and are therefore somewhat loose.
