Swedish Weights, used iy Bergman and Scheele .

The Swedish pound, which is divided like the English apothe-cary, 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 480.88719444 English troy grains,or is equal to 189.9413 English cubic inches: and the Swedish longitudinal inch is equal lo 1.238435 English longitudinal inches.

From these data, the following rules are deduced :

1. To reduce Swedish longitudinal inches to English , multiplyby 1.2384, or divide.by 0.08747.

2. To reduce Swedish to English cubical inches, multiply by1.9, or divide by 0.5265.

3. To reduce the Swedish pound, ounce, drachm, scruple, orgrain, to the corresponding English troy denomination, multiplyby 1.1382, or divide by 8.786.

4. To reduce the Swedish kannes to English wine-pints, multi-ply by . 1 520207 , or divide by 6.57804.

5. The lod, a weight -oinetimes used by Bergman, is the 32dpart of the Swedish pound ; therefore, to reduce it to the English troy pound, multiply by .03557, or divide by 28.1156.
