PERTHSHIRE service to the trade, especially as one of the founders of the book exchange in Leipsic. See Friedrich Perthes' 1 Leben, by one of his sons (3 vols., Gotha, 1848-'51 ; 6th ed., 1872; Eng- lish translation, 2 vols., Edinburgh, 1856). II. Johann Georg Justus, popularly known as JUSTUS, uncle of the preceding, founded in 1785 a pub- lishing house at Gotha, and died in 1816. This was continued by his son WILHELM (1793-1853), who was the first of the family to issue (1816) the Almanack de Gotha in French and German (Grothaisches genealogisches laschenbuch), pre- viously published by Ettinger. Wilhelm be- queathed the business, under the name of its founder Justus Perthes, to his son BEENHAED WILHELM (1821-'57), who in 1854 founded a geographical institute, which has acquired great importance within the last 20 years under the direction of August Petermann, by promoting explorations and publishing the Mittheilungen, a monthly periodical. The firm of Justus Per- thes is now conducted (1875) for account of the widow of Bernhard Wilhelm Perthes, Ru- dolf Besser being a partner. It employs more than 200 persons, and has become especially celebrated for issuing excellent maps and nar- ratives of explorations. PERTHSHIRE, a central county of Scotland, bordering on the counties of Inverness, Aber- deen, Forfar, Fife, Kinross, Clackmannan, Stir- ling, and Argyle ; area (including two small detached portions, one on the frith of Forth, and one surrounded by Stirlingshire), 2,835 sq. m. ; pop. in 1871, 127,762. The Grampians form its N. and W. boundary, and rise in the summit of Ben Lawers to the height of 3,984 ft. The county is drained by the Tay and its tribuaries and by the Forth. The Tay flows from the N. E. end of Loch Tay, a lake 16 m. long, and runs circuitously about 100 m. to the firth of Tay, from which it is navigable for ves- sels of 100 tons as far as Perth. Lochs Earn, Rannoch, and Katrine, with several other beau- tiful but smaller lakes, are in this county, which is also famous for the wild beauty of the straths or mountain passes and glens. In the low al- luvial region of the southeast is one of the finest agricultural districts in Scotland ; and in the highland districts are extensive sheepwalks. Linen and cotton are manufactured ; and the fisheries on the Tay are the most valuable in Scotland. The county was formerly divided into the districts of Gowrie, Perth, Stormont, Strathearn, Menteith, Breadalbane, Balquhid- der, and Rannoch. The principal towns are Perth, the capital, Crieff, and Dunblane. PERTY, Joseph Anton Maximilian, a German naturalist, born at Ohrnbau, Bavaria, Sept. 17, 1804.
