them to the parent bone. In this case they can be laid 

 bare and removed with bone forceps or chisel. Other 

 forms are best left to nature after all unhealthy action has 

 been subdued, and will materially diminish when preserved 

 from hard work, strains, jars and all excitants to renewed 

 growth. When continuous gentle pressure can be applied 

 without irritation it greatly favors absorption. In some 

 instances the distension of the fibrous membrane covering 

 a bony swelKng is the main cause of continued inflamma- 

 tion and lameness. This is to be met by dividing the 

 membrane with a narrow-bladed knife inserted to one 

 side of the swelling, much care being requisite to avoid 

 entrance of air, injury to joints, etc. 



SCBOFULOUS (tUEEBCDLOUS) DISEASE OF BONES. 



This is mostly seen in young animals when the bones 

 are soft and growing rapidly, and may be suspected when 

 the patient comes of a tuberculous family. It will attack 

 any part but is especially common in the lower part of the 

 limbs and is one form of "fovl in the fooi." It attacks the 

 ends of long bones or the whole bulk of short ones, those 

 parts, in short, which have an open cancellated texture. 

 The interspaces of the bony tissue fill up with gelatinoid 

 lymph, which may or may not pass into the yellow cheesy 

 tubercle, and similar changes take place on the surface, 

 long outgrowths appearing, the interstices of which are 

 filled by the same product. Ulceration ensues, sores form 

 in the skin, discharging an unhealthy matter, the softened 

 bony tissues may be felt breaking down under a probe, 

 and the ends or processes of the bones may be found, de- 

 tached from the shaft or median jDart. 



There may be coexisting tubercle in the lungs, bow(ils, 

 etc., with cough, expectoration, diarrhoea, etc., and some- 

 times in young animals the navel remains open and the 

 flrine dribbles from it continually. 



Treatment is hardly advisable as tuberculous animals 

 are undesirable aUke for breeding or for human food. It
