diseased milk and meat tin eaten the public health in as great a 
degree as bad sanitary conditions menace the households of 
man. Furthermore, sanitary conditions of the dairy, and meat 
animals and flocks exert a most salutary influence over incipient 
tuberculosis. And in view of the infinite diagnostic value of 
tuberculin, the imminence of human and animal infection is by 
this means happily removed to its remotest possibilities. 
The hygienic possibilities of breeding are far beyond the ap¬ 
prehension of the ordinary stock raiser. Could the same wide 
principles be applied to human marital relations, the race of 
man could be regenerated. In breeding, it is possible to rear 
progeny far surpassing their parentage in all desirable respects. 
Pertinent to the subject, I quote from T/ie People^s Farm and 
Stock Cyclopedia^ edited by the Hon. Norman J. Colman, and 
eleven confreres^ even though from what I wrote nearly twenty 
years since. 
“ Valuable Hints. —Dr. A. S. Heath, President of the Farm¬ 
ers’ Club of the American Institute, New York, has given some 
principles and facts of such great value that we reproduce some 
of them : 
“ The structures of animals are especially adapted to their 
demands, and vice versa. A special aptitude to fatten is incom¬ 
patible with ample milk production in the race of bovines ; and 
excessive weight of body and shortness of limbs in the horse or 
hog is not suggestive of fleetness. Variation is observed in the 
readiness of animals to adapt themselves to new conditions, and 
the changes it produces in them, and especially by hereditary 
transmission to their offspring. 
“ Cold, exposure, and neglect produce degeneration, while 
■care, shelter, and liberal feeding improve existing animals and 
their expectant offspring. These good results may also be freely 
transmitted to the progeny. Climate modifies both animals and 
plants. In tropical climates, with rich soil, many of our small 
grasses obtain gigantic growth ; and in great altitudes, with poor 
soil, both plants and animals are dwarfed. By judicious breed¬ 
ing, care, kindness, and liberal feeding, all the animals and their
