Swedish Weights and Measures, used by Bergman and Scheele.

The Swedish pound, which is divided like the English apothecary,or troy pound, weighs 6556 grains troy.

The kanne of pure water, according to Bergman, weighs 42250Swedish grains, and occupies 100 Swedish cubical inches. Hencethe kanne of pure water weighs 48083.719444 English troy grains,or is equal to 189-9413 English cubic inches; and the Swedish lon-gitudinal inch is equal to 1.238435 English longitudinal inches.

From these data, the following rules are deduced :

3. To reduce Swedish longitudinal inches to English, multiply by1.2384, or divide by 0.80747.

2. To reduce Swedish to English cubical inches, multiply by 1.9,or divide by 0.5265.

3. To reduce the Swedish pound, ounce, drachm, scruple, or grain,to the corresponding English troy denomination, multiply by 1.1382,or divide by .8786.

4. To reduce the Swedish kannes to English wine-pints, multiplyby . 1520207, or divide by 6.57804.

5. The lod, a weight sometimes used by Bergman, is the 32d partof the Swedish pound ; therefore, to reduce it to the English troypound, multiply by .03557. or divide by 28.1156. '
