so much that she could not be dried up. She was sick about three 

 weeks, but was in pasture and had a fair appetite all the time. AVhen 

 I examined her, August 16, she still had a bad cough. There was 

 dullness over the anterior and inferior portion of the right lung, with 

 partial loss of murmur and a whistling sound, At that time she 

 was said to be improving in appearance, her eyes were bright, her 

 coat smooth and glossy, and her external appearance was that of good 

 health. The second animal to become sick was Lechene. She showed 

 the first symptoms about the 20th of June. There was loss of ap- 

 petite and milk, fever, difficult breathing, and cough. She died Au- 

 gust 8, and examination showed the right lung solid and red, greatly 

 enlarged, and was described as looking like liver; it was adherent 

 to the ribs and covered with false membranes. The third cow to 

 sicken was Champion De Pansy. The first symptoms were seen Au- 

 gust 11 or 12. August 16, when I examined her, there was dullness 

 over both lungs, loss of respiration on the right side, labored breath- 

 ing, and a temperature of 105f F. August 18 this cow was killed for 

 examination, in the presence of Dr. J. H. Ranch, secretary of the State 

 board of health, Dr. X. H. Paaren, State veterinarian, both of whom I 

 had invited to be present in order that they might see the disease and 

 be convinced of its nature. An examination revealed the right lung 

 adherent to the costal pleura throughout its whole extent, and also 

 firmly attached to the diaphragm; the false membranes were yellowish- 

 white in color, and from one-fourth to one inch in thickness. Two gallons 

 of yellow effusion surrounded the lung. The lung tissue was nearly all 

 hepatized, marbled in appearance, with interlobular connective tissue 

 distended with exudation ; the pericardium was thickened and covered 

 with false membranes. The left lung was not hepatized, but it was con 

 gested throughout, and the pleura was covered with delicate, false mem- 

 branes, which were solidly adherent to the costal pleura. 



Disinfection was commenced at once at both of these places, and 

 every measure has been taken to prevent the extension of the disease. 

 The cow Lady Florentia was a very valuable animal, but 1 informed 

 Mr. Bailey it was necessary for the safety of his herd that she should 

 be slaughtered. This has since been done, and I learn that her owner 

 was fully satisfied, from an examination of her lungs, of the importance 

 of this measure. The information which I obtained here made it seem 

 very probable that Mr. Clarke had introduced the disease on his place 

 also with animals purchased at the Epler sale. He received from there 

 the cows Midnight and Nutrina of Tunlaw, and with these was shipped 

 to his place Ella Lawrence, a cow that was sent to the sale at Peoria 

 by Mr. Tripp. According to the best information I could obtain, Xu- 

 trina of Tunlaw was the first cow to sicken on Mr. Clarke's farm, and 

 she doubtless was the means of infecting his other animals. The Vir- 

 ginia sale was quite a large one, and animals from it had been sent to 

 a large number of places in different Western States. 



The condition of affairs now seemed so very serious that I returned 

 to Chicago, and, with your approval, issued the following circular:

 herds of Jersey cattle in the United States, into which new animals have "been intro-
