a common origin. The water issues at a temperature of about 150° F. A recent analysis shows the total dissolved salts to be thirty-two parts per thousand parts of water (when cold), a proportion equal to that of sea water. The specific gravity of the water is one thousand and twenty-three (distilled water = 1000). The dissolved salts are chiefly chlorides of sodium, calcium and magnesium, with a smaller proportion of sulphates and carbonates. It has been stated that the water possesses radioactive properties.
§ 7. Weights and Measures.
The metric system is followed by the Government, and its use regulated by Ordinance, but the local weights and measures are still commonly employed. These vary greatly throughout the country, but are, subject to considerable fluctuation, as follows:
(a) LENGTH AND AREA.
| 1 draa or pic | = 67 centimetres—26·38 inches. Cloth measure. |
| 1 draa | = 75 centimetres—29·53 inches. Building and Land measure. |
| 1 donum | = 1600 sq. pics—919 sq. metres—·23 acre. Land measure (4·4 donums to the acre). |
(The official donum is 919 sq. metres; in actual practice the donum ranges between 900 and 1,000 sq. metres.)
(b) WEIGHTS.
| 1 dirhem | = 48·14 grains—3·205 grammes. |
| 1 okka (oke) | = 400 dirhems—1·248 kilogrammes—2·751 lbs. |
| 1 kantar (South) | = 100 rotls—225 okkas—288 kilogrammes—634 lbs. |
| 1 kantar (North) | = 100 rotls—200 okkas—256 kilogrammes—564 lbs. |
| 1 rotl (South) | = 12 okkiahs—2·25 okkas—900 dirhems—2·88 kilogrammes—6·34 lbs. |
| 1 rotl (North) | = 12 okkiahs—2 okkas—800 dirhems—2·56 kilogrammes—5·64 lbs. |
