Fig. 112. {upper) When the bathysphere was at its lowest level, 3028 feet, only a few 

 turns of cable were left upon the naked drum. Captain Sylvester refused to let another 

 foot go out, for fear the strain on the end-tie might be too great. Fig. 113. {lower) The 

 temperature and the humidity record of Dive Number 32, to 3028 feet, is shown on this 

 graph. The temperature rose at first, and then, as we descended into the cold depths, 

 fell to 68°. The humidity fell sharply, and later, as the calcium chloride was used up, it 

 rose very slowly to a normal level.
