38 RINDERPEST. 



lumbar and sacral nerves, where tliey join the spinal cord, is ordi- 

 narily gorged with bloody serum, and in one case, in 1V95, the 

 nervous filaments were sprinkled with very small black ecchymoses. 

 The brain is not so soft as the cord ; most frequently it appears to be 

 healthy; sometimes, however, more injected, and the meninges 

 redder ; the ventricles very often filled with an abundant lemon- 

 colored serum. In one case, Dupries saw the arachnoid dotted with 

 little black ecchymoses also found on the plexus choroides. Gamgee 

 found usually redness of the meninges of the brain, and deeper red- 

 ness of the cord, especially in cases where the breathing was very 

 labored during life ; and on puncturing the dura mater four to six 

 ounces of serum escaped. 



Vlll. Urine, Blood and Milk. The urine in all cases contained 

 albumen^ in varying proportions, and in the majority of cases, blood 

 cells also. 



The blood, as in most cases in the vessels of a dead animal, 

 remains fluid for a considerable period after death. (It sticks pecu- 

 liarly to the hand. Higgins, 1st Rep., p. 119.) 



On analysis the blood was deficient in fluids and in its proper salts ; 

 with fibrine in excess. The blood of a healthy calf contained 4.53 parts 

 of fibrine and 89.69 of corpuscles in 1000 parts. After disease, which 

 was slight and induced by inoculation, the fibrine rose to 4.85 and the 

 blood corpuscles to 117.7 in 1000 parts. In a bad case the fibrine 

 amounted to 9.9 in 1000 parts. In three cases of analysis of urine, 

 the coloring matter of bile was present ; in one the bile acids were 

 present and in one ca^e examined for leucine and tyrosine, these con- 

 stituents were not found. (A. Gamgee.) 



The blood coagulates slowly but firmly out of the body. The 

 clot resembles pitch, and in the fluid state the blood has a 

 somewhat tarry or porter like appearance (PI. X, fig. 2) com- 

 pared with (fig. 1), showing the color of healthy blood. The 

 temperature of freshly drawn blood in an advanced stage of disease 

 in a cow slaughtered, was 91® Fahr., with specific gravity of 59° ; 

 the temperature of healthy blood obtained in slaughtering being the 

 same, its specific gravity 70° less. Under the microscope, the red 

 corpuscles are small and shrunken, their cell walls also shrink and 

 corrugate, and many assume a stellated form. They also cohere 

 tenaciously, the white corpuscles are greatly in excess as compared 

 with a healthy state, are swelled out, many ruptured and their 

 granular contents dispersed over the microscopic field. (PI. X, fig. 3, 

 showing Rinderpest blood compared with healthy blood in fig. 4.)
