The most interesting series of specimens in this collection comes from Desolation Valley glacier, on the southern side of the Canadian Pacific Railway, and east of the watershed. These are: (1) A roughly pentagonal slab, about 9½″ by 7″ and from ¾″ to 1″ thick, of a rather fine-grained quartzite, with some minute glittering crystals, but giving little or no effervescence with cold HCl. The surface is crowded with wavy cylinders, generally slightly flattened, varying in diameter from about ·55″ to ·15″ (but commonly about ·55″).

page 290 note 2 “Siluria,” 4th ed., p. 40. They also recall those figured by Matthew (Proc. and Trans. Roy. Soc. Canada, vol. vii, p. 159, pl. ix) under the name of Chondrites from the Cambrian (basal) of Acadia.

page 290 note 6 The form sometimes slightly resembles, though very much larger than, the marks attributed by Salter to Hymenocaris vermicauda, Prestwich, Geology, vol. ii, p. 35.

page 290 note 8 It has a faint resemblance to the Russichnites of Dawson (loc. cit., p. 597), and to one or two rather similar (but considerably larger) objects in the British Museum collection.
page 291 note 1 By the kindness of Dr. Henry Woodward I have examined the very interesting collection of rock ‘freaks’ (if such a term be permitted) at the British Museum, but it failed to throw light on these singular structures. They present a certain resemblance to some of the peculiar globular concretions in the magnesian limestone of Durham, which occasionally rise in flattened hemidonies, with a similar slight restriction of the diameter in a horizontal section. But the dents common at the top of the Canadian specimens are wanting, and the latter show no sign of a concretionary structure, which is rare in a sandstone, and so far as I am aware unknown in a quartzite. I find nothing like them in Nathorst's work (Kong. Svenska. Vetenskaps-Akad. Handlingar, xviii, 1881, No. 7), nor in Delgado's Etudes sur les Bilobites, etc.

page 293 note 1 The chemical notes throughout are the results of Professor Collie's qualitative examinations.
page 294 note 1 In 1900 Professor Collie (Geogr. Journ., xvii, 1901, p. 268) brought a few specimens from pebbles in the bed of the Bush River, some distance away to the west. One is a limestone with oolitic grains recrystallized; another contains fragments of organisms, ill preserved; two show a coral which, according to Mr. E. T. Newton, F.R.S., probably in one case, certainly in the other, belongs to the genus Diphyphyllum.
page 296 note 1 Professor Collie informs me that it was found “just above the bands of Cambrian quartzite, the same as occurs on Mount Hector and elsewhere.”
page 296 note 2 It is some ten miles N.N.W. of Mount Noyes.
