Page 517 - The Doctor adds beautifully and most ingeniously : — ' The results arising from these facts are not confined to animal physiology ; they give information also regarding the condition of the ancient sea and ancient atmosphere, and the relations of both these media to light, at that remote period when the earliest marine animals were furnished with instruments of vision, in which the minute optical adaptations were the same that impart the perception of light to crustaceans now living at the bottom...
Page 290 - On the occurrence near Shrewsbury of Marine Shells of existing species in transported Gravel and Sand, resting upon a peat bog which contains imbedded Trees;" by Joshua Trimmer, Esq., FGS In November of last year Mr. Trimmer noticed, that in widening the road about five miles from Shrewsbury, towards Shiffnal, some very black timber was extracted from beneath a bed of loam and gravel ; and having subsequently examined the spot, he has communicated his observations in this paper.

Page 519 - ... pleased an Omnipotent and Eternal Being to manifest his creative power, we have at least succeeded beyond all hope in carrying back our researches to times antecedent to the existence of man. We can prove that man had a beginning, and that, all the species now contemporary with man, and many others which preceded, had also a beginning, and that, consequently, the present state of the organic world has not gone on from all eternity, as some philosophers have maintained.

In the peaty field, in fifteen years, about three inches and a half had been well digested. It is probable, however, that the process is continued, though at a slow rate, to a much greater depth; for as often as a worm is compelled by dry weather, or any other cause, to descend deep, it must bring to the surface, when it empties the contents of its body, a few particles of earth. The...
Page 573 - The worm is unable to swallow coarse particles, and as it would naturally avoid pure lime, the fine earth lying beneath either the cinders and burnt marl, or the powdered lime, would, by a slow process, be removed, and thrown up to the surface. This supposition is not imaginary, for \n the field in which cinders had been spread out only half a year before, Mr.
Page 572 - These are now buried at the depth of one inch, forming a line of black spots parallel to, and above, the white layer of lime. Some other cinders, which had been scattered in another part of the same field, were either still lying on the surface, or entangled in the roots of the grass. The second field examined was remarkable only from the cinders being now buried in a layer, nearly an inch thick, three inches beneath the surface. This layer was in...
Page 366 - A few inches only above what was taken as spring-tide high-water mark were putrid shellfish and sea-weed, which evidently had not been wetted since the upheaval of the land. One foot lower than the highest bed of mussels, a few limpets and chitons were adhering to the rock where they had grown.
