In No. 7 both eggs are fused completely and form one giant embryo with one set of organs. Cases like this are very frequent in the material treated with KCl. Nos. 8 and 9 are examples of the fusion of more than two eggs. I have seen four eggs form one giant embryo with one common dark center and one common clear area. Such mon- sters swam, but usually died sooner than the single embryos. Digit
