482 UTERUS, BY DK. K. CHROBAK. 



epithelium. According to Reichert* and Ercolani,f it is a pavement 

 epithelium, which the latter author also maintains is the character of 

 the epithelium lining the glands of the Dog and Mouse. In regard to 

 the Pig, the Ruminants, and Solipedes, most observers agree in stating 

 that their glands are lined by columnar epithelium. Very recently 

 a treatise has been published by Friedlander,J in which the author 

 makes mention of the " ciliated columnar epithelium " of the glands 

 of the uterus (p. 25) and cervix (p. 45) in Man, and of the uterine 

 glands in the Dog (p. 55). Friedlander appears to accept these as 

 facts (though they are certainly not generally admitted), without 

 further explanation. This is so much the more remarkable, as we may 

 satisfy ourselves that the exhibition of the cilia of the cells in question 

 is a matter of extreme difficulty in preserved specimens, as will be 

 presently shown, and we are left quite in the dark as to the means 

 by which Friedlander was successful in obtaining distinct evidence of 

 the cilia. It would appear that he must have had preserved specimens 

 under observation, and it would therefore be still more desirable to 

 learn the method he adopted. Moreover, his statement that he 

 observed ciliated epithelium in the cervix of girls not yet arrived at 

 puberty, is not in accordance with observations of many others. 



Lott observed ciliary movement in the epithelium of the 

 uterine glands as far as to their fundus, in fresh specimens 

 taken from the Cow, Sheep, Pig, Babbit, Mouse, and a species 

 of Bat. In four instances, examination of fresh specimens gave 

 a negative result; these cases were those of the Calf, a very 

 young Guinea-pig, a dissected Pig, and a Mare suffering from 

 pyaemia. 



In a few cases he observed lively ciliary movement in the 

 epithelium of the gland, when not only had all movement
