This woman was the mother of ten children besides the product of this conception, and at the latter occurrence had entire absence of pains and a very easy parturition. Pincott had a case with an interval of seven weeks between the births; Vale 1 of two months; Bush 1 of seventeen days; and Burke 1 with an interval of two months. Douglas cites an instance of twins being born four days apart. Bessems of Antwerp, in 1866, mentions a woman with a bicornate uterus who bore two twins at fifty-four days' interval.英文原著 · 《Anomalies and Curiosities of Medicine》

"Here," -- and long intervals of silence between. Plain as if written on a page was the thing they told.英文原著 · 《Ramona》
Then the bishop began to be particularly tormented by a bird that made a short, insistent, wheezing sound at regular intervals of perhaps twenty seconds. If a bird could have whooping-cough, that, he thought, was the sort of whoop it would have. But even if it had whooping-cough he could not pity it.
