Post-mortem Re-port: Body well nourished, carpal and tarsal joints 

 extremely swollen, skin in tension over the joints, strong 'fluctuations 

 noticeable. The left carpal joint contains a large quantity of light yellow, 

 slightly slimy, fluid with small threads of fibrine. The articulatio ante- 

 bracheo-carpalis has slight defects of the cartilage, capillary ramifications 

 and easily removable deposits of fibrine. The intercarpeal articulation 

 contains larger flakes of fibrine which are specially located in places 

 where there is least friction. The articulatory capsules of these joints 

 are extremely moist and thickened ; their synovial coating forms folds 

 in many places ; the same lesions were found in other joints. In the 

 left talo-crural articulation the deposit of fibrine is membranaceous. The 

 cartilage under it has two round circumscript defects ; 3| c.c. synovial 

 fluid could be collected from this joint alone by means of the syringe. 

 The Ugaments of all the joints show serous imbibition to a great degree. 

 The tendovagina of the left musculus digitalis profundus is thickened and 

 rich in fluid. The internal coating has small punctiform haemorrhagies. 

 The atlantoepistrophical articulation is naturally strongly involved on 

 account of its frequent motion when the calf was sucking. The capsule 

 of the -joint is thickened by a flbrinous exudate. 



Pathological-Anatomical Diagnosis : Polysynovitis and Tendovaginits 

 serofibrinosa, as a sequel of pleuro-pneumonia. 



CASE 3. — Ox 672 was injected on the right side of the dewlap with 

 5 c.c. fluid (one part fluid derived from the joints of the last case diluted 

 with ten parts of bouillon Martin). On the seventh day after injection 

 a -large oedematous swelling appeared, synchronising with a rise of tem- 

 perature. On the tenth day two pieces of the base of the dewlap, from 

 surface and from depth, were excised to enable histological diagnosis to 

 be made. The animal was slaughtered on the twelfth day for experi- 

 mental purposes. 



Post-moiiem Report: The right side of the dewlap shows a tumour 

 5D cm. by 25 cm. The subcutaneous tissue is spongy, filled with a yellowish 

 serous fluid which coagulates quickly. The muscles and intra-muscular 

 tissue shows the usual lesions. The humor of the deeper layers contains 

 flakes of fibrine. Abomasus hyperaemic, mucosa swollen and covered 

 with slightly bile-stained mucus ; omasus normal ; contents of reticulum 

 very dry ; rumen normal, containing a small quantity of food. Coecum 

 and colon normal ; ileum shghtly congested ; jejunum, mucosa swollen, 

 difiuse ramifications of the blood vessels and hyperaemia of the folds. 

 Mesenterial lymphatic gland swollen, somewhat soft ; right lobe of lungs 

 in posterior part not collapsed ; pleura rather whitish, milky, tough. The 

 tissues of the other portions of the lungs normal. Foam in trachea. Heart 

 contracted, left ventricle empty, endocard normal ; right ventricle empty, 

 endocard a few white patches. Liver normal ; spleen shghtly swollen, 

 pulpa soft, trabecles distinct. Kidneys shght hyperaemia of cortex, in 

 two, lobuli a few smaU white points of the character of infarcts. Synovia
