M. Thury bored a hole, of about 10 inches in depth, in the flooring of ice, and placed a thermometer in it, at 12.25 P.M., closing it up with cotton. At 2.55 P.M., and at 4.7. P.M., the thermometer marked the same temperature, namely, 26°·24 F. M. Thury's views on glacières in general, based upon the details of the three which he has visited, are much the same as those which I have expressed. He has, however, more belief than I in 'cold currents.' FOOTNOTES: [Footnote 217: This was given by a thermometer only placed in the cave at 7 P.M., and by construction not very sensible.] [Footnote 218: The moment when the disturbance of the atmosphere commenced.] [Footnote 219: M. Thury gives--4°·62 C. as the minimum in the glacière during the night in question; but on the next page he gives--6°·8 C. (=19°·76 F.). It is evident, from a comparison with other details of his observations, that the latter is the correct account.] * * * * * End of the Project Gutenberg EBook of Ice-Caves of France and Switzerland by George Forrest Browne
