508 GOOD AND BAD POINTS OF CATTLE, AND 
superficies of the body, but more internally : the North Devon is 
a small-boned and kindly animal, and disposed to fatten either 
externally or internally. A North Devon is a bad handler, with 
other points good : physiologically speaking, we should infer that 
fat would be deposited internally, from the skin being thick and 
inelastic, shewing the absence of those tissues that are for the re- 
ception of fat externally. Suppose we have a South-hammer, a 
good handler, with a mellow and plastic skin, and every other de- 
notation of being disposed to fatten, the probability is that the fat 
would be deposited externally. In my humble opinion, it is so with 
every other breed. We must attend more to the external form and 
quality, in conjunction with locality, climate, and soil. Guernseys 
or Alderneys make fat but very indifferently externally. I well 
know practically, that an animal of either breed, with a good skin, 
and good bone, &c.is inclined to fatten on the outside ; but when 
such is the case, there is an absence of it internally. The circula- 
tory system, with the local form of an animal, may also be reck- 
oned amongst those causes which tend to balance the fat indiscri- 
minately either inside or out. Say that an animal kindly disposed 
to fatten has a few points that preponderate ; for instance, he is 
large over the surloin — the bloodvessels, nerves, and muscles of 
such a part take on a corresponding size. When he begins to 
have more food given to him, the circulatory system becomes 
more full of blood, and, as a natural consequence, the larger parts 
have a greater influx of blood ; thus the growth of these parts 
either in fat or muscle, and they become of larger proportions, 
and deposit more fat than those which are not commensurate in 
vascular action. 
Before concluding these remarks, I beg to offer an opinion 
respecting small lungs, as stated by Dr. Lyon Playfair (at a 
meeting of the Council of the Royal Agricultural Society), 
that they are more favourable to the formation of fat. Dr. P. 
says, horses have large lungs. I well know, and not speculatively, 
that horses, if fed on meal and potatoes, or turnips, quickly and 
rapidly make fat. In fact, this is the compost that horse-dealers 
use to puff up the farmers’ cattle, so as to give them a glossy 
and plump look previous to sale, and the being put to work in 
this state oftentimes causes their death. On opening them, I 
have seen them loaded with fat. 
Now this is not in accordance with Dr. Playfair’s views. My 
firm conviction is, that animals with small lungs in their growing 
state will in proportion suffer in their external form. From ob- 
servations I have made on animals of divers breeds, I come to 
this conclusion, that they make fat internally or externally, regu- 
larly or irregularly, in accordance with the organization in struc-
