THE ATLANTIC. 



[chap. III. 



27tli in 2325 fathoms, with a bottom of gray ooze with nod- 

 ules of black manganese, and a bottom temperature of 0°-4:7 C. 

 The distance from the Cape of Good Hope at noon was 138 

 miles. A series of temperature soundings were taken at inter- 

 vals of ten fathoms from the surface to a depth of a hundred 



fathoms with the following results 



60 fathoms 11°-2C. 



10 " 11-1 



80 " 11-1 



90 " 11-0 



100 " 10-9 



On the 28th we stopped at 7 a.m., and sounded in 1250 fath- 

 oms with a bottom of gray mud, Table Mountain and the range 

 of hills above Simon's Bay being fairly visible on the north- 

 eastern horizon. We took a series of temperatures at intervals 

 of ten fathoms down to a hundred. At noon we took a second 

 series, fifteen nautical miles to the sonth-west of the Cape of 

 Good Hope, and we found that in the interval we had passed 

 into the loop of the Agulhas Current, which curls round the 

 Cape close to the land. The contrast between the two series is 

 remarkable. 



The temperature of the air likewise rose perceptibly, the 

 thermometer in the shade indicating at noon 15° C, nearly 

 three degrees above the average of the same hour during the 

 previous week.
