ANATOMY OF VERTEBRATES. 



membrane is ciliate. Such is the structure of the human oviduct, 

 as shown in the preparation, No. 2823, A, xx. vol. iv. p. 189 ; but 

 there are varieties, as in fig. 550. A remnant of the primordial 

 oviduct, or ' duct of Muller,' is constant, in the form of the 

 pedunculate hydatid, fig. 550, i. 



The human uterus, of the shape and dimensions shown in the 

 sections, figs. 551 and 552, is more compact, more muscular, than 

 in Quadrumana, has a broader and more convex fundus, a more 

 marked constriction between the incubating and transmitting parts, 

 and these are more distinct in their respective structures. The 

 former, fig. 551, uc, which is analogous to and homologous with

the 'cornua uteri' of brutes, is termed, in Anthropotomy, the 

 * body': the part, ib. c c, which answers to the « corpus uteri in 

 brutes, fig. 546, b, c, d, is termed < cervix uteri.' The relations 

 above enunciated receive an interesting confirmation m the oc- 

 casional anomaly of the human uterine structure shown in fig. 541. 

 The enlargement for the lodgment of the foetus and its appen- 

 dages is limited to the incubatory part, the inner surface of which 

 in the unimpregnated womb is smooth, and by contact closes the 

 cavity, as at i, fig. 552. The cervix, i, p, has its inner surface in- 

 creased by numerous plicate folds and furrows ; in many instances 

 diverging from an anterior and posterior medial longitudinal
