I have seen the thing working itself out in one case known to me.

The cases of the three former officials were known from news reports and previous books about the period.

Classes are not usually so large, of course, but such cases have been known.

"This case is now known about from one coast to the other and then some."

There have been cases known in which woman gave birth to eight children at once.

The case is known in the region as the "Three missing women."

Only 23 such cases are known to the foundation, which has files on 3,000 children.

Although several such cases were known, most scientists suspected that it was a matter of chance.

Although lethal cases are known, he made a full recovery.

Yet not a single case of sabotage was known to have occurred.
