Plate 1

3 Cat; 7-mm. embryo. Median sagittal section, showing the anterior end and the entire pharyngeal extent of the notochord, in its relation to neural tube and pharynx. Hypophyseal region is at the right. X 375.

4 Cat; 12.5-mm. embryo. Nearly median section, showing the chondrifying basilar plate, etc. Hypophyseal region is at the left. X 37%.

5 Cat; 16~mm. embryo. Median sagittal section, showing notoehord, basilar plate, craniopharyngeal canal, etc. The anterior end of the notochord is cut twice. Hypophysis to the right. The hollow hypophyseal stalk appears two sections (20 ,u) away, roughly perpendicular to the pharyngeal epithelium which it joins. X 41.

6 Cat; 28»mm. embryo. Nearly median (parasagittal) section. Shown are perichondrium and fascia pharyngobasilaris, etc. Edge of hypophyseal fossa is at the right. Two artificial wrinkles of basilar plate are present. X 41.

7 Cat; 50-mm. embryo. Nearly median section. Caudal portion of pharyngeal region, to show an unusual bursal outpocketing. To the left is the transverse pharyngeal vein with the dorsal edge of the pharyngeal musculature immediately below. A longitudinal medial lymphatic channel is above the bursa. The basilar cartilage and perichondrium are at the top. Epiglottis occupies the lower portion. Caudal edge of the soft palate appears at the right. X 371}.

8 Cat; young adult. Vertical section of pharyngeal tonsil showing lymphatic infiltration of the ciliated epithelium over a nodule and escape of lymphocytes. X 285.
