39 페이지 - Some isolated portions of meteorites have also a structure very similar to that of stony lavas, where the shape and mutual relations of the crystals to each other proved that they were formed in situ on solidification.
461 페이지 - From the 3rd to the oth of August the upper stake had moved twelve inches, and the lower one six. Unfortunately some uncertainty attached itself to this result, due to the difficulty of fixing the lower stake.
