The winter presents a marvellous contrast to that of England, which can often show one hour and five minutes' sunlight in the twenty-four, or 2.8 per cent. of its possible duration.
THE TIDES
In El-'Akabah are like Suez: first of month, flood, 6--12 a.m. and p.m.; ebb, the rest. But at Suez the tides rise one metre, and at times two metres; at El-'Akabah (February 7), one foot.
For the instruments NOT used in this Expedition, see Chap. I. p. 11.
The barometre aneroid sold by M. Ebner was partially repaired by M. Lacaze, and served for Mr. David Duguid's observations.
My pocket set by Casella (maker to the Admiralty and Ordnance) consisted of--
One watch aneroid (compensated, 1182).
Two sets wet and dry bulb thermometers (one broken).
One set maxima and minima thermometers, Nos. 12,877 and 12,906.
Two pocket hygrometers not numbered.
