121 experiments are reported in Gallus domesticus, in which the left optic primordium from donor embryos ranging from stages 9 to 17 (Hamburger & Hamilton) was grafted upside down into host embryos at approximately stage 11-(12 somite stage), replacing the host right primary optic vesicle, which had previously been removed. In 36 experiments, up to donor stage 12+, the choroid fissure in the graft developed in hostwise ventral orientation, i.e. from the original dorsal quadrant of the graft. In four cases no fissure appeared. In donor stage 17 grafts, the fissure was invariably in graftwise dorsal orientation. In the intermediate donor stages 14 and 15, hostwise fissures occured in 12 out of 23 experiments, and in the donor stages 15 and 16, in 7 out of 28. Six cases were seen in which the fissure was in a position approximately midway between the hostwise and graftwise positions. Multiple fissures were not encountered. The results are compared with those reported in Trition by Sato (1933).
本文报道了121例针对家鸡的实验，其中将处于第9至17阶段（汉堡和汉密尔顿分期）的供体胚胎的左视原基倒置移植到约处于第11阶段（12体节期）的宿主胚胎中，替换先前已被移除的宿主右初级视泡。在36例实验中，直至供体阶段12+，移植体中的脉络膜裂以宿主方向的腹侧方向发育，即从移植体原来的背侧象限发育。在4例中未出现裂隙。在供体阶段17的移植体中，裂隙始终处于移植体方向的背侧方向。在中间供体阶段14和15，23例实验中有12例出现宿主方向的裂隙，在供体阶段15和16，28例中有7例出现。观察到6例裂隙处于宿主方向和移植体方向位置之间大致中间的位置。未遇到多条裂隙的情况。将结果与佐藤（1933年）在 Tritition 中报道的结果进行了比较。
