MICROSCOPIC ANATOMY OF THE PULP. 

 FIG. 62. FlG 63 . 



According to the mi- 

 croscopic observations of 

 Mr. Nasmyth, the pulp 

 consists of a structure 

 essentially cellular, (as 

 exhibited in Fig. 64, A.) 

 which he calls the ret- 

 icular tissue. These cells 

 constitute the "principal 



FIG. 62 represents the vascularity of the pulps of one of the central incisor 

 teeth of the upper jaw. The deeper vessels are seen to be large, and the 

 looped communication between the capillary arteries and veins is distinctly 

 shown. The small figure shows the pulp of natural size. 



FIG. 63 represents the pulp of an adult bi-cuspid, and the arrangment of 

 its nerves magnified twenty times.
