A few old adhesions were found; otherwise, with the excep- tion of the distended tube, everything was normal. The right tube was removed. The unruptured specimen v;is brought to the laboratory and fixed in formalin. The uterine end is apparently normal and the clot protrudes from the fimbriated end. .Sections were cut from four

The heart shows the same spiral arrange- ment as in the chick embryo. At four weeks the embryo is about 5 mm. long and weighs about 20 mg. (Fig. 186). At this stage 40 somites are present, the arm and leg buds have formed, and the embryo corresponds roughly to about a
