About five-and-twenty years ago a large boulder, lying in the garden of Wimpole Hall, near Koyston, was pointed out to the Rev. Osmond Fisher by the Lady Hardwicke of that period, and s-he informed him that it had been brought from near Old North Eoad Station when the hill there was lowered. As its dimensions and nature had not been determined, Mr. Fisher invited me to accompany him to Wimpole on April 22nd in order to examine it, having previously obtained permission from the present owner of the property, Lord Eobartes. After a brief search the boulder was discovered lying about 30 yards north-west of the conservatory and almost concealed under a dense growth of ivy. It measures approximately 8 ft. 10 in.inlength, 4 tt.inheight, and lft. 8 in.inbreadth, and consists of a greenish-grey tough sandstone. Mr. Fisher determined its S.G. to be 191 and its weight to amount to 3 tons 2cwt. Lithologically the rock is precisely similar to portions of the Spilsby Sandstone of Lincolnshire, and a specimen in the Woodwardian Museum from near Claxby is indistinguishable from it. By good luck a small Ammonite occurred in a fragment chipped off by the Kev. E. Conybeare, who met us at Wimpole; and Mr. G. C. Crick, of the British Museum, who has kindly examined it for us, writes that it ia “ not referable to any species which has hitherto been recorded from Great Britain, “but that it” is closely related to Olcosteyhanus (Craspedites) subdilus (Trautschold), which has been recorded from the Spilsby Sandstone of Lincolnshire (Pavlow and Lam pi ugh, ‘Argiles de Speetpn,’ etc., p. 116, pi. xiii (vi), figs. 5a, b, c).“

Before the last meeting of the British Association, held in Liverpool, Professor Edward Hull presented a paper upon “Another Possible Cause of the Glacial Epoch.”inthat paper, Professor Hull applied the writer's work on the “Reconstruction of the Antillean Continent,” which brought together evidence of great continental elevation. This elevation and its effects upon the ocean-currents, in diverting them from the West Indian regions, with the consequent reduction of their temperature as they reach the northern latitudes in conjunction with the elevation of the land, were thought by Professor Hull to be sufficient causes for the production of the glacial climate over temperate regions in late geological times. The writer has hitherto never applied his observations on high continental elevation to climatic changes; but in this paper he proposes to extend briefly his researches from the Antillean region to the higher latitudes of America and the North Atlantic regions. Something has also been learned of the date of the great elevation; consequently inferences may be drawn as to climatic changes.

The majority of fossiliferous beds in the Cambrian are of anargillaceous nature, and limestones are comparatively rare, but weneed not here enter into a discussion as to the causes of their rarity.When, however, we come to the Ordovician, we find calcareous bedsmuch developed, and since we find in them, as well as in the slatesand shales, these blind genera, and as far as we know not lessabundantly, it appears as if the physical conditions of sedimentationhad but little to do with the existence and perpetuation of theseforms.

The Red-Deer (Cervus elaphus), or common stag, is a native of the more temperate regions of Europe, Asia, and North America, lu Great Britain it has its freedom limited to the Highlands of Scotland, where, however, it is carefully protected, and affords the crême de la crême of British field-sports to the practised rifleman and mountaineer.

In describing “An Interesting Contact-Rock” (Geol. Mag., March and April, 1895) I gave its analysis, showing:—

And in this rock also the great relative increase in soda corresponds with the appearance of albite among the new minerals.
