10 EXPLORATIONS, WESTERN ATLANTIC, STEAMER BACHE, 1914. 
The course of the Challenger in 1873 crossed that of the Bache -at 
Bermuda, allowing a direct comparison of the vertical distribution 
of temperatures for 1873 (Murray, 1884) and 1914 in that neighbor- 
hood. The temperature series taken by the Challenger about 260 
miles south of Bermuda in March of that year (Challenger station 29),
