IN 1913 George G. Scott reviewed the then existing literature and added experiments of his own on the remarkable ability of adult Fundulus heteroclitus to withstand wide variations in the osmotic pressure of their environment1. The significance of his conclusions is retold in the easily observed hardiness of these teleosts. The survivors of such changes appear to function adequately to gross observations. Similarly the Fundulus embryos, although less than 2 mm. in diameter, and with tissues that are readily torn with sharp glass needles, will develop in extremes of distilled water and sea water with salts or sucrose added up to twice the normal osmotic pressure. |
