the first had had two tusks of the largest size, whilst the second had 

 none, or any trace of alveolus. Two lower jaws in the cabinet of the 

 Society, of nearly the same age, (described and figured in the Trans. 

 Vol. IV". Plates XXIV. and XXV.) were also destitute of tusks, or al- 

 veoli for them. 



Dr. H. examined the analogies adduced by Prof. Owen in support 

 of his theory, and expressed the opinion that they were very remote; 

 and as the extensive knowledge of that distinguished naturalist had 

 not furnished him with closer ones of the desired character, it was 

 clearly presumable that none could be adduced. 



A much closer analogy, Dr. H. observed, was to be found in the 

 Dinotherium, a very nearly allied animal; but so far as its remains, 

 hitherto obtained, enabled us to decipher its history, it was furnished 

 with two tusks in the lower jaw. 



On the whole, Dr. H. saw little reason to change the opinion first 

 expressed by him (see Trans. Vol. IV. p. 318.) that "it is impossible 

 in the existing state of our knowledge, and with our present materials, 

 either to confirm or positively refute the suggestion," that the tusks 

 in the lower jaw are a mere sexual character. The honour of esta- 

 blishing this point is yet to be reaped. Should the suggestion, how- 

 ever, prove correct, Dr. H. believed it would be found that the male 

 had two tusks in the lower jaw, instead of one, as supposed by Prof. 

 Owen ; and that the jaw in Mr. Koch's collection, containing a single 

 tusk, is to be considered an anomaly.
