PEEFACE. 



IN introducing a Second Edition of this Manual but 

 few words are necessary. It has been entirely revised, 

 some portions, notably the chapter on the dental tissues, 

 have been in great part rewritten, and many new illus- 

 trations have been added here and elsewhere in the 

 book. 



My indebtedness to Professor Owen's " Odonto- 

 graphy," to my father's "Dental Surgery," and to 

 his " Lectures on Dental Physiology and Surgery," to 

 Professor Flower's " Lectures on the Teeth " (published 

 in the British Medical Journal, 1871), to Kolliker's 

 and to Strieker's Histologies, I will again acknow- 

 ledge, since it is both impossible and undesirable to 

 encumber a student's book with references to au- 

 thorities for every statement. And if I have any- 

 where failed to give due acknowledgment to another 

 whose writings I may have made use of, I crave forgive- 

 ness for my omission. I gladly embrace this opportunity
