The minion aiid allailtoistwo of the extraembryonic structures of the avian embryopossess dynamic physicochemical systems which provide arid maintain an adeqnate cnviroiixrierit for the developing embryo within tlie egg. Vital and sigiiificant physiological activities occur within these sys- tems. Oiic of the most striking of thesc activities is the twofold process of extracting 10 to 15 nil of very dilute aqueous solutions from the albumeii and maintaining thesc dilute solutions against the more concentrated yolk aiid alburncn.

Studies by Aggaezotti ('13) and Ramei ('27), and more recent ones by Ronianoff and Hayward ('43) and Walker 'This woik v-as supported in p a r t by a W. D. James Felloidiip * Research Fellow in Chemical Embryology.

## Abstract This study provides a quantitative analysis of the active movements of the chick embryo and of the contractions of the amnion over the entire developmental period of 21 days. Four types of embryo movements are distinguished. The motor activity of the embryo shows two characteristic peak

Chick embryo retinas were cultured with [3H]glucosamine on each day between days 6 and 12 of development. The total labeling of gangliosides decreased from day 6 to day 12. The decrease was mostly due to the decrease in the labeling of disialosyllactosylceramide (GD3), which diminished to less than
