| Popis: | In 1918 I made some preliminary experiments on the effect of iodine upon the metamorphosis of salamander larvae; these were entirely unsuccessful and the intention of making further experiments on this problem was given up. Soon after this, however, Swingle (1) published his first experiments on the acceleration, by inorganic iodine, of the metamorphosis of tadpoles and the correctness of my own observations became doubtful. Therefore, I have repeated, following- closely the method employed by Swingle, my former experiments on the larvae of salamanders. These experiments confirmed in every respect the observations made during my first experiments and revealed the astonishing fact that exactly the same treatment, i. e., the administration of inorganic iodine, which produces precocious metamorphosis in tadpoles, has not the slightest effect on the metamorphosis of salamander larvae, although iodothyrine causes prompt metamorphosis in the salamander larvae just as it does in tadpoles. |
