the eastern half of the Mediterranean Sea. This they have 
accomplished, and no doubt their results in this respect are fairly 
accurate. With this object in view they took complete sets of 
observations at as many different stations as possible, and at 
stations in as many different situations as possible. After finish- 
ing a set of observations at one station at early morning, they

would, for example, steam off to another station twenty or thirty 
miles distant, and make similar observations at the new station at a 
later hour the same day. They never made two sets of observa- 
tions in the morning and afternoon of the same day at the same 
place. For our present purpose a few days’ steady observations 
at the same station would have given more useful results than can 
be derived from the observations as made. Still, by comparing 
the temperatures at different depths at contiguous stations, for 
which the times of observation did not differ by more than ten 
or twelve hours, we may hope to get some data available for our
