Abstract
Summary
Triturus viridescens ovulated extra-seasonally after implants of mouse anterior pituitary averaging 12.6 mg, although the reaction was slower and less complete than that after approximately 0.84 mg of newt whole pituitary substance, or the ovaries increased markedly in size if the above dosage of mouse pituitary was distributed over a long period (30 days). Rana pipiens, however, gave no ovulatory response although much larger doses (35.23 to 229.2 mg) of mouse anterior pituitary were given.
