Autojjsy 8. — A yearling heifer, Much serum was found in the chest, 

 and the pleural surfaces were extensively adherent. The sub^^tance of 

 the right lung was completely marbled, some parts having suppurated 

 while others were only indurated. — Dr. Tyler, April 27, 1860. 



Other examinations are reported in connection with the herd, 

 but in such language that no definite conclusion can be drawn 

 from them. 



Alclen Olmstead' s Herd. 



Monday, November 28, 1859, Leonard Stoddard sold a pair 

 of oxen from his diseased herd to illden Olmstead, of the same 

 town. Mr. Olmstead kept the oxen till the next Saturday, and 

 then exchanged them for another yoke belonging to William 

 F. Doane, who kept them until they were killed on May 9th, 

 1860. This yoke of oxen showed at their examination after 

 death unequivocal marks of disease of a character similar to 

 that previously described. 



Li two weeks after these oxen left Mr. Olmstead's herd, one 

 of his (Olmstead's) animals, was attacked with coughing, shiver- 

 ing, grunting, and rapid respiration. In two or three weeks it 

 died, but there was no post mortem examination. One animal 

 after another was taken sick, so that on the 12th of April seven 

 out of twenty-three had died, or were so near death, that, to 

 prevent hopeless suffering, they were slaughtered. Many of 

 the remaining animals were in a bad condition, and the entire 

 herd was finally slaughtered by the Commissioners. Several 

 examinations were made. 



Aiitopsjj 9. — Killed a cow which had been sick nineteen days. She 

 was feeble, had but little a|)()etite, diarrluca, cough, and shortness of 

 breath. Hair rough, &c. Percussion dull over all the left side of chest, 

 with absence of respiration. The left pleural cavity contained several 

 gallons of serum, by estimate. Over the costal pleura was a firm layer 

 of lymph resembling tiie velvety parts of tripe. The whole lung was 

 indurated, especially at its base, and brittle, like liver. No pus. Right 

 side and lung healthy. — Dr. Martin, April 11, 18G0. 



Autopsy 10. — Killed a cow 10 years old. Sick since January. Dul- 

 ness over tiie left side. On opening it there was a gush of Icctid matter
