 Reichert, and Henle, and find little favor among 

 English and American histologists. 



A part of this system, also, according to Virchow, 

 are the so-called dentinal tubules, the lacunae and 

 canaliculi of bone, even the continuity traced by 

 Gerlach, between the ciliated cells of the aqueduct 

 of Fallopius; that by Heidenhain|||| and BriickeTl 

 between the lacteals and cylinder epithelium of the 

 intestinal villi of the rabbit, by means of corpuscles 

 of connective tissue; in the epithelium of the endo- 

 cardium by Luschka;*** and the results of similar 

 observations by Eckhart,ftt Billroth, Jit and Fried- 

 reich.
