This Table was calculated at a temperature between 
46° and 55°; but Mr Kirwan has reduced part of it 
to the temperature of 62°, in order to compare it with 
the specific gravities of sea water taken at that tempe 
rature, or at least reduced to it. The specific gravi 
ties, thus altered by Kirwan, are as follows:
