A Military Academy was formed, principally with a view to bring forward extraordinary talents and employ them in the civil or military public service. Anyone was admissible. The children of the meanest mechanics and day-labourers, provided they had _very extraordinary natural genius_, a healthy constitution, and a good character, were educated. It was an establishment designed for the encouragement of genius, and for calling forth into public utility talents which would otherwise remain buried and lost in obscurity. Measures were adopted for improving the breed of horses and horned cattle in Bavaria and the Palatinate. An attempt was made to put an end to usury in Munich and to improve the highways and public roads, by employing the soldiery in repairing them and preserving order and public tranquillity on them. A new English Garden was formed, beginning upon the ramparts of the town. It was nearly six English miles in circumference. Within the Garden was a fine and very valuable farm, with thirty of the finest cows procured from Switzerland, Flanders, the Tyrol, and other places. There was a public coffee-house in the middle of the Garden for refreshment and public resort. The scientific work which Sir B. Thompson did whilst in the service of the Elector of Bavaria between 1783 and 1794, shows his energy and originality, his accuracy and his depth. When at Mannheim in July 1785 he made experiments in the presence of Professor Hemmer, of the Electoral Academy of Sciences of Mannheim, on the propagation of heat through various substances; on the increased difficulty of conduction of heat through the torricellian vacuum; on the effect of humidity in increasing the conducting power of the air; and on the effect of air of different degrees of density. The Duke ordered the meteorological instrument maker to the academy at Mannheim to come to Munich, and to spare neither labour nor expense in providing the complete apparatus necessary for the experiments. These experiments, on the relative conducting powers of mercury, water, air, and a torricellian vacuum, were read to the Royal Society, March 9, 1786. He then proceeded to make experiments on the relative warmth of various substances used in making artificial clothing; relative quantities of the same substance; different qualities of substance chemically, as charcoal, ashes, dust. All his experiments indicated that the air which occupies the interstices of substances used in forming coverings for confining heat acts a very important part in that operation. Air is a perfect non-conductor of heat. These experiments were chiefly made in 1787. They were not read before the Royal Society until January 19, 1792.
