Studies conducted by Witschi and Riley (1940) on a large number of human pituitary glands similarly showed no correlation between age, sex, and MSH activity. In all the tests performed, 0.1 mg of acetone-dried pituitary powder ve a positive chromatophore-dispersing reaction in the Rana clamitans larvae. 

Binding to or interference with the thyroid hormone receptor has not been directly tested in amphibians. No effects on metamorphosis were reported in laboratory studies mX. laevis (17,19,23) Rana clamitans, or R. pipiens (6,28). 

Orientation via chemical cues may be more important in some species than in others. For example, Oldham (1966, 1967) studied homing and orientation in American toads Bufo americanus) and green frogs Rana clamitans). Oldham (1966) partially destroyed the olfactory tracts of 99 American toads and used 99 intact toads treated as operational controls. An additional 112 toads were left untreated. The toads were then transported to a point of land between two pools. About the same frequencies of returns occurred to the pools. Oldham concluded that olfaction was not necessary for orientation and homing in American toads. However, since only a portion of the olfactory system was destroyed, it is possible that olfaction was still involved in homing and orientation.
