Prevention. 949 



swine herds in wliieli it had, year after year, taken large toll. 

 Colts should not be fed with bran at all, or only in small 

 amounts. Moreover, the young animals should be protected by 

 cleanliness and proper ventilation of their stables against acute 

 diseases which may establish a predisposition to rickets, and 

 they should be kept as much as possible in the open where 

 they can move about freely. All these precautions are called 

 for especially in pure-bred or high grade herds in which the 

 greater or lesser degree of inbreeding of itself reduces the re- 

 sistance of the animals. 



If there is a suspicion of infectious or tcxic rachitis, the isolation 

 of the diseased animals and the disinfection of their stables, as well 

 as a change of feeding, is indicated.

Barlow's Disease. In a young dog, which during life had shown 

 signs of rickets, rheumatoid pains and debility, and which had often 

 cried out in pain, Stoltzner found rosary-like thickenings of the 

 cartilaginous ends of the ribs, a large subperiosteal hematoma of the 

 scapula, a considerable swelling of the proximal epiphyseal end and 

 of the adjoining diaphyseal portion of the humerus, with a large double 

 hematoma. The lower two-thirds of the radius were thickened on 

 account of a subperiosteal hematoma; where the swelling was largest, 

 both in the humerus and in the radius, the corticalis was entirely 

 absent. Histological examination showed that there was not a bone 

 fracture, but that the cortical portion, and in places the spongy portion 

 also, had become rarified; osteoid trabeculae and osteoblasts were 

 present in only small numbers, the epiphyseal marrow contained fat 

 cells and the diaphysis showed a spleen-like structure. Definite rachitic 

 changes were not ascertained. 



The author emphasizes justly the great similarity of the clinical 

 picture with Barlow's Disease, whicli occurs in children together with 

 rickets and which leads to hemorrhages in bones and elsewhere, but 

 he nevertheless does not feel justified in identifying the affection with 

 Barlow's Disease. (Schmorl, Beitr. z. path. Anat., XXXX, 215.—
