If, however, they are left in the sea-water containing the saponin they undergo, a few minutes after membrane-formation, the disintegration known in pathology as CYTOLYSIS. Membrane-formation is, therefore, caused by a superficial or incomplete cytolysis. The writer believes that the subsequent treatment of the egg with hypertonic sea-water is needed only to overcome the destructive effects of this partial cytolysis. The full reasons for this belief cannot be given in a short essay.英文原著 · 《Darwin and Modern Science》
Since the entrance of the spermatozoon causes that degree of cytolysis which leads to membrane-formation, it is probable that, in addition to the cytolytic or membrane-forming substance (presumably a higher fatty acid), it carries another substance into the egg which counteracts the deleterious cytolytic effects underlying membrane-formation.英文原著 · 《Darwin and Modern Science》
As this institution is principally designed as a nursery for genius,--as a gymnasium for the formation of men,--for the formation of REAL MEN, possessed of strength and character, as well as talents and accomplishments, and capable of rendering essential service to the state; at all public examinations of the pupils, the heads of all the pupil departments are invited to be present, in order to witness the progress of the pupils, and to mark those who discover talents peculiarly useful in any particular departments or public employment.英文原著 · 《ESSAYS-1》

As far as I can judge it will be a curious little book."英文原著 · 《The Life and Letters-2》
