It is said that duties may be laid upon the publications so high as to amount
to a prohibition.
If we suppose the amount of change between each horizontal line in our diagram to be excessively small, these three forms may still be only well-marked varieties; or they may have arrived at the doubtful category of sub-species; but we have only to suppose the steps in the process of modification to be more numerous or greater in amount, to convert these three forms into well-defined species: thus the diagram illustrates the steps by which the small differences distinguishing varieties are increased into the larger differences distinguishing species.
In the diagram I have assumed that a second species (I) has produced, by analogous steps, after ten thousand generations, either two well-marked varieties (w10 and z10) or two species, according to the amount of change supposed to be represented between the horizontal lines.
If then our diagram be assumed to represent a considerable amount of modification, species (A) and all the earlier varieties will have become extinct, having been replaced by eight new species (a14 to m14); and (I) will have been replaced by six (n14 to z14) new species.
Owing to the divergent tendency of natural selection, the extreme amount of difference in character between species a14 and z14 will be much greater than that between the most different of the original eleven species.
If, in our diagram, we suppose the amount of change represented by each successive group of diverging dotted lines to be very great, the forms marked a14 to p14, those marked b14 and f14, and those marked o14 to m14, will form three very distinct genera.
Purposely he hesitated and haggled over the amount
, but Paulvitch was obdurate.
"Impossible!" said Dantes, staggered at the enormous amount
Let no one be surprised at the vastness of the amount
. The work of casting, boring, masonry, the transport of workmen, their establishment in an almost uninhabited country, the construction of furnaces and workshops, the plant, the powder, the projectile, and incipient expenses, would, according to the estimates, absorb nearly the whole.
The sum amounted
to a little over twelve thousand dollars.
Over his features played an eager desire to state the amount
of his valor in a similar crisis, but the narrator proceeded.
To appreciate the full magnitude of this stroke, consider these other figures: the annual expenses of a national government amount to the equivalent of a contribution of three days' average wages of every individual of the population, counting every individual as if he were a man.
Little crudities of a mechanical sort were observable here and there, but there were not enough of them to amount to anything, and it was good enough Arkansas proof-reading, anyhow, and better than was needed in Arthur's day and realm.
Notwithstanding the amount of his "bills payable," Mr.
The Society can be in no such hurry for its subscriptions; they must amount to a good deal."
