General Zoology
This little book contains a surprisingly large number of good descriptions of experimental techniques, presented with enough theory to make them intelligible. The chapters deal with blood, the circulation, respiration, muscle, peripheral nerve, the physical basis of body heat exchanges, and electronics in physiology. The methods are all physical rather than chemical, and such topics as electro-...

Oxygen consumption, heart rate, and thermal tolerance were measured in week-old embryos of Heermann's gull ( h r u s heermanni). Heart rate and oxygen consumption are temperature independent between 30 and 40 C and average 120 beats/min and 1.87 cm3 Ot/(egg-h). Below 30 C, these rate processes become strongly temperature dependent, and the heart stops beating when cooled to 7-13 C. The beat rec...
