has existed in New Jersey and New York, it is thought advisa- 

 ble to make the following extract. 



The disease was introduced into Brooklyn by a cow imported from 

 Germany in 18i3, and taken directly from ship-board into one of the 

 large milk dairies of that city. In the county of Kings the disease has 

 lurked until the present time, making its incursions into other parts of 

 the country as opportunities to convey it have offered, by the transfer of 

 some animal from an infected herd. 



In 1853 the disease was carried by a cow to Mr. Prentice's farm at 

 Mt. Hope, near Albany ; a cow originally from the dairy of Mr. P., 

 after wintering in Brooklyn, was being returned to him, bearing the 

 disease with her. Thus introduced into his herd, it extended from one 

 animal to another, not ceasing to do its work until such a perfect separa- 

 tion of the animals was affected, that not more than two, in most cases 

 but one animal Avas kept in a place. Early impressed with the convic- 

 tion tliat the disease was of a contagious character, and that Ids 

 tlUurij security was in prevention and not in remedy, Mr. Prentice 

 resorted to a quarantining of the sick and a rigid isolation of the remain- 

 der, as above detailed, and thus controlled the disease. 



On the testimony of jNIr. Jolnison, the disease was carried to his farm, 

 near Newark, by animals which he purchased in the New York market. 

 Sickening soon after their arrival, the disease was first communicated to 

 animals in the contiguous stalls, and from them to others, till all the cattle 

 on the form have been the subject of it. Isolation has not been resorted 

 to here, and the whole history cannot now be written, for nuich seed we 

 fear has been sown that when ripened into harvest may give us a sad 

 appendix. The history of the other outbreaks of the disease in New 

 Jersey, viz., in the herd of IMayor Edgar, at Kahway, and others in 

 Morris County, if written, would be in corroboration of what we have 

 here given. 



Second. Its identity is proclaimed by a similarity of symptoms, 

 mai-king tlie period of inculjation, development, progress and termina- 

 tion of the disease in all the localities in which it has been observed. 

 The description given by Mr. Prentice of the disease in his herd was as 

 like to that of Mr. Johnson as language can portray disease. AVhen the 

 disease, as it appeared in tlie Johnson herd, witnessed by your commis- 

 sion, was described to the veterinary surgeons at Boston, they declared 

 it at once identically the same. Not one symptom noted in the sick liere 

 but has been observed in INIr. Johnson's animals. 



The post mortem examinations declare quite unequivocally their iden- 

 tity. The same engorged condition of the lungs, producing an increase 

 in the size of the or";an that would seem almost incredible to one who
