These fossils are in the cahinet of the proprietor of the estate on which they 

 were discovered. In the year 185t!, a fine tusk of elephant was taken out of the same 

 p;ravel; curved rather more than half a circle, measuring seven feet on its outer curve, 

 three feet of the hollow base being wanting. It was seven laches in diameter at 

 its proAimal end, and nearly 4 inches in diameter at its distal extremity. This 

 fine fossil tusk is now in the Sudbury Museum, 



The gravel in which the above and many other mammalian fossils have been 

 discovered belongs to the Boulder- Clay formation. And in it the boulders of 

 nearly all known British rocks may be recognized, especially those which are 

 sufficiently hard to have survived the transit hither, such, for instance, as the 

 various sandstones, and the hardest of the Oolites. Here we meet with boulders 

 and angular blocks of the calcareous grit of the Heddington quarries, near 

 Oxford; others very much like the forest-marble, and inferior oolite, greensand, 

 and an abundance of hard chalk; some of these fragments are angular, while 

 others are perfectly smooth and rounded. 



The matrix in which these minerals and organic fossils are embedded is, in one 

 part of this extensive detitral deposit, a greyish sand ; at others a yellowish clay, 

 of which bricks are made. 



This interesting deposit of boulder-clay and gravel assumes a thickness here of 

 from 30 to 40 feet on the right bank of the river Stour as we descend that stream, 

 and continues for several miles to the pleasant little town of Bures St. Mary, 

 forming small abrupt hills and valleys with beautiful undulations. 



There is not perhaps a detrital deposit in England where a greater variety of 

 fossils might be obtained than where the above mammalian remains were found. 



Yours truly,

Note ox Eauthquakes, by John Calveet, F.G.S., C.M.E., &c.— Shocks 

 of earthquakes are of such frequent occurrence in the West Indies, and tropics 

 generally, that few residents make any close observation or record of those awful 

 phenomena. At the same time, the houses being for the most part built of wood, 

 the immediate personal danger_cannot be considered an ordinary excuse. During 

 a residence of several years in Jamaica, I witnessed so many that latterly I became 

 more sensible of their approach, and w^as the better prepared to observe theii- 

 effects. The most fearful shock I witnessed was in 1852, about ten o'clock p.m* . 

 I was standuig at a drawing-table, when 1 became suddenly sensible of its 

 approach by the peculiar and indescribable feeling of faintness and despondency 

 that is invariably the precursor or physical effect of them ; and in an instant i 

 found my ruler rolling towards me, which as soon took the opposite direction away 

 from me. The pictures on the wall swung to and fro six or seven times, at inter- 

 vals of about two and a-half seconds ; the glasses jingled on the sideboard. The 

 horses and cattle pasturing round the house stumbled and ^ran about visibly 

 nllcctcd • .he blood-hounds in the house growled, and distended theii' legs, slidin- 

 on the iH^Uiantly pohshed tloors; even the poultry gave evidence of th?ii^ excite^ 

 ment. Ihe negroes fell on their knees to supplicate protection, and all creation 

 seemed io be made mstantaneously sensible of that Divine power that "weighed the 

 mountams in scales, and the earth in a balance." I felt like the ant whos-^ 

 industry I ha.^ often watched, and with the stamp of my foot LSn £ an
