Abstract

This is a study of the effects of temperature on morphogenesis, and is an attempt to determine whether the order of appearance of anatomical features can be altered within the limits of survival. The time in days (usually from closure of the blastopore) for features to appear was noted, and from this the rates were calculated, being the reciprocals of days X 103. Rate plotted against temp. gives in general a straight line whose slope may be calculated. Some slopes were: hatching, 4.6; digestive system, 6.4; skeleton, 6.5; nervous function, 8.2; external pigment, 9.6; blood vessels, 10.0; fins, 10.3; eye pigment, 12.5. Thus hatching would be expected to appear precociously at low temps., and eye pigment at high temps.
