    P. 173. (80 X 3 + 16 X 6) = 336 + 12 water 108 = 444. Berzelius’s number for silica is three times that of Thomson’s. P. 175. 1 atom of nickel 26 + 1 of sulphur 16 = 42. P. 176. 1 atom of bisulphuret of nickel 58 + 1 of biarseniuret of nickel 102 = 160. P. 177* For 26 X 3 + 62 X 2 = 202, read 34 X 3 + 62 X 2 = 226 + 162 = 388. The weight of the atom of nickel has been taken by accident for that of its oxide. P. 183. 1 atom of uranium 125 -]- 1 atom of oxygen 8 — 133. The peroxide may be consi- dered as containing half as much more oxygen as the protoxide, in which case it will consist of 2 atoms of uranium 250 + 3 of oxgen 24 = 274. Brande considers the atom of uranium to be 64, (oxygen being 8) and that the protoxide contains 1 atom of oxygen, the peroxide 2 atoms.
