Hyperconcentrated

An elaborate study of oversaturated solutions of uric acid and its salts has been made by Kohler. In this work he has demonstrated, by means of dialysis and electric conductivity, that in hyperconcentrated solutions of sodium urate we are not dealing with a colloidal but with a true oversaturated solution.

Another group of plants was planted in the Tortugas sand and kept in water of the following concentrations: 100, 75, 50, 20, 10, and 5% fresh, and 100% salt water. In a previous season records were taken on plants grown in hyperconcentrated sea-water, 140% salt The record for these plants gave a very slow rate of growth, and alter lingering for a few weeks, the plants yellowed, dropped the leaves, and died. These experiments were not repeated.

Again when the olfactory apparatus is exposed to too great a quantity of perfume, nothing but an indefinite odor can be perceived. In harmony with this is the fact that when a hyperconcentrated odor is submitted to the spectrum it is seen that the ultra-violet rays are entirely absorbed, without any separation into the usual absorption bands.

A second operation revealed, in addition to the original ulcer on the lesser curvature, an ulcer of the pylorus and an ulcer on the jejunal border of the gastro-enterostomy opening where the hyperconcentrated fluid passed without stagnation. There was no ulcer in the lower pouch where the hyperconcentrated fluid became stagnated.

Since the bees bring in and accumulate much more pollen than is necessary, One can easily remove a part in order to study the composition and its hyperconcentrated food value. We know, through chemical analysis, what are the particular essentials of pollen, its richness in proteins and in free amino acids on one hand, and vitamin B (complex) on the other.
