[2] Readers who wish a more detailed account of a greater variety of splashes are referred to papers by the author. Proceedings Royal Society, vol. xxv. pp. 261 and 498 (1877); and vol. xxxiv. p. 217 (1882).

[5] The black streaks, seen especially in Figs. 11, 15, and 16, are due to particles of lamp-black carried down by the drop from the surface of the smoked watch-glass on which it rested.

[6] Three of these photographs, viz. Nos. 11, 12, and 17, are reproduced full size, as a frontispiece, by a photographic process, to enable the reader to form a more correct idea than can be gathered from the engravings, of the amount of detail actually obtained, though even in these reproductions much is inevitably lost.
