In tlic anterior part of the ventral ?wall on each side there is seen the soparate rudi-ment of the heart, in the simple vascular tube of which are to be distinguished tliehinder auricular, the middle ventricular and the anterior bulbous parts. There are tenproto-vertebral segments. Fig. 7C7.—Views from below op the kmerto-rabeit of nine days and three HOURS, showing THE COMMENCING HEART IN TWO STAGES. f. (A. T.) These sketches, of which B and 0 are partly diagrammatic, were taken from twopreparations given me by Professor Kolliker. A is the view from below of one of theembryoes in which the formation of the heart was least advanced, and of which an out-line of the heart, &c., is repeated in B. In C, taken from the second preparation, thetwo halves of the heart are seen in the commencement of tbeir coalescence. Ii, thepart of the bent tube which becomes the vent
