EXPLANATION OF THE PLATES. 



PLATE XXII. 



All the figures in this plate are human. 



Fig. 1. Tesselated epithelium from the serous coat of the 



liver ; from some of the cells the nuclei have 



escaped. 

 Fig. 2. Ditto from the choroid plexus ; the spines described 



by Henle as proceeding from the angles of the cells 



must be of unusual occurrence, as I have never yet 



seen them. 

 Fig. 3. Ditto from the vena cava inferior in different stages 



of development, from the white corpuscle of the 



blood upwards. 

 Fig. 4. Ditto of the arch of the aorta ; some of the cells are 



seen to have lost their nuclei. 

 Fig. 5. Ditto from the surface of the uterus of a woman who 



died suddenly during lactation. 

 Fig. 6. Ditto from the internal surface of the pericardium.
