REPORT ON THE DEEP-SEA DEPOSITS. 
415 
DIAGRAMS. 
Diagrams 1 to 22 show the vertical distribution of Temperature, the relief of the Bottom of the Sea, the 
nature of the Deposits, and the percentages of Carbonate of Lime. In these Diagrams horizontal lengths or 
distances from Station to Station are on a scale of 200 miles to the inch, and the depths are on a scale 
of 500 fathoms to the inch, so that depths or heights, as compared with horizontal distances, are 
exaggerated in the proportion of 400 to 1. In looking, therefore, at the Plan as one of tlie bed of the 
area, it must be remembered that the inclines as observed were 400 times less steep than they are repre- 
sented. The Diagrams show the isotherms for every five degrees, which were obtained by plotting the 
temperature observations on paper of equal squares and drawing the curves (the observations and curves 
are published as Part III. of the Physics and Chemistry of the Expedition). 
In the Diagrams the thick Horizontal lines represent lines of equal temperature in Fahrenheit 
00 
Scale. The figures above each Vertical line, thus, q , indicate, the number of the 
lO

cq 
Station, 68 °, the Surface Temperature, and, 2650 , the Depth in fathoms. The figures below 
each Vertical line indicate the temperature at the Bottom, the type of Deposit being- 
given with the percentage of Carbonate of Lime underneath.
