"The various phases of germination of spores of Bacillus ramosus, as actually observed in hanging drops under very high powers. The spore sown at 11 A.M., as shown at a, had swollen (b) perceptibly by noon, and had germinated by 3:30 P.M., as shown at c: in d at 6 P.M., and e at 8:30 P.M.; the resulting filament is segmenting into bacilli as it elongates, and at midnight (f) consisted of twelve such segments." — The Encyclopedia Britannica, 1910

Portion of the germinal membrane, with rudiments of the embryo, from the ovum of a dog. The primitive groove, A, is not yet closed, and at its upper or cephalic end presents three dilatations, B, which correspond to the three divisions or vesicles of the brain. At its lower extremity the groove presents a lancet-shaped dilation (sinus rhomboidalis) C. The margins of the groove consist of clear pellucid nerve substance. Along the bottom of the groove is observed a faint streak, which is probably the chorda dorsalis. D. Vertebral plates.
