contains more iodine than a quart of cow's milk.
Iodine exists in arable land.

It is abundant in sulphur, iron, and manganese ores, and sulphuret of mercury: but rare in gypsum, chalk, calcareous and silicious earths.

Any attempt to extract iodine economically should be made with the plants of the ferro-iodureted fresh waters.

Most of the bodies regarded by the therapeutists as pectoral and anti-scrofulous are rich in iodine.
It is probably to the application of this body that we owe the discovery of the daguerreotype.

There is no record of the precise date when Daguerre commenced experimenting with iodine, but by the published correspondence between him and M.Neipce, his partner, it was previous to 1833.
