ALTITUDES.

The number of trustworthy altitudes resulting from these observations is not large, but amongst the localities determined in a satisfactory manner are Eubaga, the capital of Uganda, and the level of the Victoria Nyanza. For Eubaga Mr. Wilson and Mr. Felkin have supplied satisfactory sets of observations for thirteen months, whilst at Makongo, on the shore of the lake, Mr. Wilson observed during nearly two months. Two instruments were used at Eubaga, viz., Mr. Wilson's " J. Browning, No. 952," and Mr.

Felkin's "Newton, No. 1137." They both kept pace well together, the " Newton " keeping uniformly T05 (with correction, T34) in. ahead of the "Browning." The latter, on its return to England in Jane 1880, was tested at Kew, when it was found to need a correction of 0'28 in. under a pressure corresponding to that prevailing at Eubaga.

This quantity we have deducted throughout Table III.

The resultant altitudes (computed from Guyot's and Eadau's tables), under the assumption of a mean pressure of 29'9 in. at the sea-level, are as follows : Feet above sea-level.
