times highly cylindrical, yet, on the other hand, the wild form 

 sometimes has it quite straight ; (3) this has been shewn by the photos, 

 to be a matter of degree in both wild and tame forms, both possessing 

 individuals whose foreheads shew straightness and varying degrees of 

 concavity ; (4) this also is shewn by the photographs to be an indi- 

 vidual characteristic, and that it is so is also said to be the case by 

 Col. Pollok ; (5) examination of the photos, shews here also connecting 

 links throughout, and it will be observed that in this case it is amongst 

 the wild forms that most of the links are shewn ; (6) in this point I 

 have had to give my personal experience to shew that it is an indivi- 

 dual characteristic, but I am supported in what I have written 

 by the many recorded observations of naturalists and sportsmen 

 who, each giving their own personal view of the matter, shew, by the 

 wide divergence of their opinions, that there is every degree of 

 dewlap to be found in different specimens, from the smallest to 

 such as are of some size ; whilst in some, many perhaps, there is 

 none at all. 



With regard to points 1 and 7, size and variation of colour, it will 

 probably be admitted by everyone that these are so essentially matters 

 of domestication that they need not be considered. 



Finally, although it has nothing to do with my arguments, or any- 

 one else's as to the difference or non-difference of the two species, yet 

 it may be of interest if I close my article with a note on some measure- 

 ments of horns of the two forms. 



Such of the measurements as I cannot guarantee to be correct I 

 place in brackets, the others I vouch for being absolutely correct. 



Of my wild heads the finest I consider to be that shewn as e in both 

 series. The measurements are as follows : — 



Tip to tip round sweep ... 75§r inches.
