The second column gives the temperatures observed at the respective depths when the convection currents were stopped by the use of the geo-thermometer. The third column gives the temperature of the water in the bore-hole when the convection currents were allowed to circulate. The fourth column gives the alteration of temperature at each depth which arose from stopping the convection currents— minus-when the temperature fell, plus when it rose. The fifth column gives the increase of temperature at each depth over that at the previous one, as taken from the second column. The sixth column gives the rate of increase at each depth, measured by the number of feet which it would be required to descend to gain an increase of 1 degree Réaumur, > commiclsoolkks (CO)
