But we have seen that a thick fossiliferous formation can only be accumulated during a period of subsidence; and to keep the depth approximately the same, which is necessary in order to enable the same species to live on the same space, the supply of sediment must nearly have counterbalanced the amount of subsidence.
Many instances could be given of beds only a few feet in thickness, representing formations, elsewhere thousands of feet in thickness, and which must have required an enormous period for their accumulation; yet no one ignorant of this fact would have suspected the vast lapse of time represented by the thinner formation.
He who can read Sir Charles Lyell's grand work on the Principles of Geology, which the future historian will recognise as having produced a revolution in natural science, yet does not admit how incomprehensibly vast have been the past periods of time, may at once close this volume.
Moreover, between each successive formation, we have, in the opinion of most geologists, enormously long blank periods.
With respect to the terrestrial productions which lived during the Secondary and Palaeozoic periods, it is superfluous to state that our evidence from fossil remains is fragmentary in an extreme degree.
The most skilful geologist, if his attention had been exclusively confined to these large territories, would never have suspected that during the periods which were blank and barren in his own country, great piles of sediment, charged with new and peculiar forms of life, had elsewhere been accumulated.
Consequently formations rich in fossils and sufficiently thick and extensive to resist subsequent degradation, may have been formed over wide spaces during periods of subsidence, but only where the supply of sediment was sufficient to keep the sea shallow and to embed and preserve the remains before they had time to decay.
During periods of elevation the area of the land and of the adjoining shoal parts of the sea will be increased, and new stations will often be formed;--all circumstances most favourable, as previously explained, for the formation of new varieties and species; but during such periods there will generally be a blank in the geological record.
The DRA increases the look-back period to five years; under the prior law, the look-back period was three years for transfers to individuals and five years for transfers to a trust.
The aggregate amount which would be includible in gross income with respect to such instrument for periods before the close of any accrual period (as defined in Sec.
The incubation period for HCPS caused by Andes virus has not been reported.
No, Rev Proc 2004-51 put an end to building on one's own property and taking title to such property as improved even if one transfers the property to an intermediary or other agent first which holds the property during the 180 day exchange/improvement period and then transfers it back as improved.
