Mean weights of chick embryos correlated with the stages of Hamburger and Hamilton



Mean weights of chick embryos correlated with the stages of Hamburger and Hamilton



Journal of Morphology 124(1): 79-82



A total of 1125 normal chick embryos, representing 25 each of the 45 stages of Hamburger and Hamilton, were removed, fixed in Bouin's solution, stored in 70% ethanol and weighed with a semi-micro analytical balance. Entire blastoderms of stages 1-8 were weighed, whereas only embryos-proper were weighed in stages 9-45. As a consequence, results constituted 2 groups, each of which showed a geometric rate of growth marked only by minor deviations which.were related to specific events of normal growth and development.
