Dr. Lamont, also, in his article, gives us the following table of the magnitude of the variations derived from observations at Gottingen: +--------------------+ | Year.|Mean of Year.| |--------------------| | 1835 | 9.57 | | 1836 | 12.34 | | 1837 | 12.27 | | 1838 | 12.79 | | 1839 | 11.03 | | 1840 | 9.91 | | 1841 | 8.70 | +--------------------+ A comparison of these tables, and particularly the latter, with Schwabe's table of spots, is interesting. There is obviously a greater mean variation when the spots are most numerous. Comparing the two with the tables of Hildreth, in relation to the temperature, from 1830 to 1840, there is, to say the least, a most remarkable coincidence. And there are others equally remarkable.
