But a deeper reason than this has been assigned for the importance of embryology in classification. It has been asserted, and is implied by Darwin in the passage quoted, that the ancestral history is repeated in a condensed form in the embryonic, and that a study of the latter enables us to form a picture of the stages of structure through which the organism has passed in its evolution. It enables us on this view to reconstruct the pedigrees of animals and so to form a genealogical tree which shall be the true expression of their natural relations.英文原著 · 《Darwin and Modern Science》
SIR: By the act of Congress, approved June 30, 1882, all army-officers are retired on reaching the age of sixty-four years. If living, I will attain that age on the 8th day of February, 1884; but as that period of the year is not suited for the changes necessary on my retirement, I have contemplated anticipating the event by several months, to enable the President to meet these changes at a more convenient season of the year, and also to enable my successor to be in office before the assembling of the next Congress.英文原著 · 《Memoirs of General William T.

Now, again, this leisure would enable me to please myself and expand my mind by travelling if I had a mind to it: because, say, for instance, that I were a shoemaker; if due social order were established, it by no means follows that I should always be obliged to make shoes in one place; a due amount of easily conceivable arrangement would enable me to make shoes in Rome, say, for three months, and to come back with new ideas of building, gathered from the sight of the works of past ages, amongst other things which would perhaps be of service in London.英文原著 · 《Signs of Change》
To illustrate his care he pointed out to us a cabinet directly back of the operating-table, lined with thick sheets of lead. From this cabinet he conducted most of his treatments as far as possible. A little peep-hole enabled him to see the patient and the X-ray apparatus, while an arrangement of mirrors and a fluorescent screen enabled him to see exactly what the X-rays were disclosing, without his leaving the lead-lined cabinet.英文原著 · 《The Silent Bullet》
The house in Evelina Road was no mere haunt of quiet gentility. It was chosen with admirable forethought and with a stern eye upon the necessities of business. Beyond the garden wall frowned a railway embankment, which enabled the cracksman to escape from his house without opening the front door. By the same embankment he might, if he chose, convey the trophies of the night's work; and what mattered it if the windows rattled to the passing train?英文原著 · 《A Book of Scoundrels》
At first, truly, to all them that, professing learning, inveigh against poetry, may justly be objected, that they go very near to ungratefulness to seek to deface that which, in the noblest nations and languages that are known, hath been the first light-giver to ignorance, and first nurse, whose milk by little and little enabled them to feed afterwards of tougher knowledges. And will you play the hedgehog, that being received into the den, drove out his host? {3} or rather the vipers, that with their birth kill their parents?英文原著 · 《A Defence of Poesie and Poems》
