360 ON THE ENAMEL AND DENTINE OF THE TEETH 



to be bona fide additions to our knowledge ; in fact, one might almost 

 fancy M. Kdlliker addressing to M. Lent, Balak's famous rejaroach to 

 Balaam — " I called upon thee to curse this people, and, lo ! thou hast 

 blessed them these many times.'' 



So far as I am personally concerned, I care little enough about 

 being absorbed, after Professor Kolliker's ordinary fashion, in the 

 next edition of the ' Mikroskopische Anatomie,' where we shall, I 

 doubt not, read, " I and Huxley have made out that the enamel is 

 formed under the membrana preformativa," &c., &c. But I think 

 that Professor Kolliker will do well to reflect whether he is likely to 

 increase his most deservedly high reputation by encouraging in a 

 student a disingenuousness of which he himself, I hope, would be 

 heartily ashamed. 



I may add, in conclusion, that there are, I believe, two very good 

 minor grounds of cavil in my paper. One is at page 159, where I 

 state incidentally that Professor Kolliker does not mention Nasmyth's 

 discovery in his ' Mikroskopische Anatomie ' — an error for which I 

 cannot account, and for which I can only apologise, as a complete 

 oversight. The other is the description of the cement of the calf's 

 tooth at page 162 ; in which a subsequent examination has led me to 

 think there are errors of interpretation. I have had no leisure to 

 re-examine this point, and I recommend it to MM. Lent and Kolliker, 

 if, as it would seem, they have some unaccountable source of satis- 

 faction in finding me wrong — a thing I do myself, quite without 

 .satisfaction, every day.
