It lies close beneath the surface, and follows for a length of one hundred and fifty miles the margin of a grand basin or plain; this, from its outline, manifestly must once have been a lake, or more probably an inland arm of the sea, as may be inferred from the presence of iodic salts in the saline stratum.
In absence of the latter, and therefore in presence of compounds which destroy or absorb hydriodic acid -- e.g. iodic acid -- there results a _brown_ addition product.
Ba (C.O_3) _2 · H_2O, and begins to decompose on being heated to 250° C. Barium iodate, Ba (IO_3) _2, is obtained by the action of excess of iodic acid on hot caustic baryta solution or by adding sodium iodate to barium chloride solution.
The iodic acid test is very delicate, but requires great care, and may be used in the presence of organic matter.

This acid is not so poisonous as hydriodic or iodic acids.
Other leaves in iodic acid, diluted to the same degree, showed after 2 hrs. 15 m. the same shrunken appearance of the purple fluid within the cells; and these, after 6 hrs. 15 m., were seen under a high power to be filled with excessively minute spheres of dull reddish protoplasm, [page 51] which by the next morning, after 24 hrs., had almost disappeared, the leaf being evidently dead.
