the usual method , it is a little difficult to microscopically observe chicken embryos immediately after spawning . However by using the polyethylene − wrap method , it becornes easy to observe the developing embryQ after the definitive streak stage 〔 about 18 hrs after incubation at 38℃ ) . In our experiment , we carried out a modification Qf the polyethylene − wrap method for chicken embryo cu 工 tures without shell . We observed developing embryos continuously during the 3 to l8 days after

With this modified polyethylene − wrap method , the various develop − mental stages of embryos , primitive knot ( Henzen ' s nQde } , notochord , neura !tube , somites , tail bud , fore ・ limb for wing bud , hirld ・ limb bud and other basic organ rudiments of the embryo were easily 〔 〕bservable . The observation of the development of chicken embryos has the potential to be a useful
