Froin Cape of Good Hope to Melbourne. 91 Challenger left her anchorage in Simons Bay , the 17th December, 1873. Between 10 and , she traversed a current of cold water with a surface-temperature of 13° C, or 5° below the temperature recorded at4 At noon the thermometer had again risen to 18°. 3 C,and at 3 to 19°. 2 C. After sailing at midnight on thefollowing day through a second streak of cold water, the shipcrossed the northern limit of the Agulhas Current betweenI and 2 of the 19th December, at which time the surface-temperature was observed to rise to 22°. 2 C. Towards noon ofthe same day, and at Station 143, distant about 150 nauticalmiles from the Cape, the thermometer recorded the maximumof 22°.8 C. It next fell to 22°.? C, and, with the exceptionof a cold streak of I9°.4 C. observed in the course of the20th December, remained stationary until 2 on the 21st,between which hour and it fell from 2 2°. 2 C. to20°.6 C. T
