EPITHELIUM OF THE MUCOUS MEMBRANE. 481 



Man and various animals for ciliary epithelium, does not mention the 

 uterine glands at all, and Hennig* was even led to the conclusion, in 

 regard to the glands he observed in the Fallopian tubes, that the 

 principal difference between follicular organs and simple folds of the 

 mucous membrane in the human Fallopian tubes depends on the pre- 

 sence or absence of a deciduous ciliated investment on the mucous 

 surface. 



Henle alsof expressly states that the columnar epithelium of the 

 glands differs from that of the free surface of the uterine mucous mem- 

 brane in the absence of cilia. 



The other statements in regard to this epithelium are very con- 

 flicting. The majority of authors, indeed, ascribe the possession of 

 columnar epithelium to Man and most Mammals, yet not to all. 

 Differences of opinion exist even in regard to Man ; for whilst, for 

 example, Weber, J Kolliker, Leydig, || Henle, ^f Frey, ** and 

 Hennig,tt describe a columnar epithelium, others, as Gerlach, jj 

 Scanzoni, and Schroder, |||| maintain that it is tesselated. 



Kolliker expressly terms it an ordinary, Henle and Hennig a 

 ciliated columnar epithelium, whilst Leydig observes "that in all 

 probability the epithelium of the glands exhibits as much ciliary 

 movement as the rest of the internal surface of the uterus." 



The statements, again, that have been made in regard to various 

 animals, are not quite in accordance with one another. LeydiglTIF 

 ascribes to the glands of most Mammals (ciliated?) columnar
