While the insect fauna of European countries was investigated by local naturalists, the spread of geographical exploration brought ever-increasing stores of exotic material to the great museums, and specialization - either in the fauna of a small district or in the world-wide study of an order or a group of families - became constantly more marked in systematic work.
The "sources" made use of by Orosius have been investigated by T.
While the subject of the testing of petroleum for legislative purposes has been investigated in Great Britain by committees of both branches of the legislature, with a view to change in the law, the standard has never been raised, since such a course would tend to reduce the available supply and thus lead to increase in price or deterioration in quality.
