PREFACE TO THE FOURTH EDITION. 
More than a quarter of a century has elapsed since~I first 
attempted to describe the dog in his several varieties, together 
with the uses to which he is put in this country and the diseases 
which attack him. Until within the last ten years the societies 
formed in aid of this investigation have chiefly taken in hand the 
management of public shows of this animal, but recently special 
clubs have been formed which have undertaken to settle the points 
of the particular breeds which has been selected by them, and 
their descriptions have in each case been taken by me in lien of 
those I had previously drawn up, even when I have not been able 
fully to agree with them. 
I have also added descriptions of several breeds which have 
either come out from obscurity, as in the case of the Basset 
Hound, Welsh and Scotch Terriers, &c., or manufactured, as in 
that of the Irish Wolf-Hound. These additions are necessary to 
render complete any treatise on the dog in the present day. 
The treatment of his diseases is also brought down to that of 
modern times.
