Speaking of contagious pleuro-pneumonia, it gives us pleasiu 
to print a letter addressed to Dr. Hopkins by Professor M 
Eachran at the time of the last national convention of catt 
growers. An opinion expressed by Dr. McEachran must alwa^ 
carry its weight. His long experience with the disease and b 
many opportunities to battle with it and to apply the means 1 
which he has so often conquered it, will render his letter intc 
esting to the profession, and we hope will also tend to enlighti 
our legislators as to the measures most necessary in contendii 
successfully with the common enemy. 
How far removed, indeed, is his strong and emphatic recoi 
mendation of the stamping out process, from the uncerta 
and inefficient, and dangerous, withal, measure of inoculatio 
which has been at once opposed by many and vindicated 1 
others. The following extract deals a telling blow against tl 
adoption of the inoculation plan in this country , except under tl 
most guarded and efficient regulations, strictly and conscientious 
enforced. 
THOEOUGHBEED CATTLE DYING. BLOOD POISONING IN NEW JEESEY HEEDS API 
INOCULATION WITH IMPUEE YIEUS. 
Mount Holly, Nov. 23, 1886.—The great increase in the number of cases 
blood poisoning among thoroughbred cattle in Burlington and adjoining counti 
has filled cattle breeders with alarm, as the veterinarians have been unable 
cope with the disease. 
The disease first made its appearance on the Sooy farm, not far from 1 
county line, among a lot of Ayrshire and Jersey cattle. The symptoms w 
clearly those of blood poisoning, and in a few days several of the animals di 
Since then a number of additional deaths have occurred, and the disease appeal 
among the thoroughbred Channel Island cattle in the vicinity of Mount Hoi 
Medford and on the borders of Atlantic county. 
As far as can be learned not a single animal recovered from an attack 
the malady. This increased the feeling of alarm already existing among breedc 
and they accordingly summoned Dr. W. B. Miller, of Camden, one of the oflic 
of the State Board of Health. Dr. Miller made an investigation which led 
strange developments. He learned that prior to the appearance of blood pois 
ing there had been a good many cases of pleuro-pneumonia, to avoid the spreac 
which inoculation had been resorted to by local veterinarians. In nearly ev 
instance the animal so inoculated w T as seized with blood poisoning and died, 
each instance the tail of the inoculated animal began to swell and decay, i 
death soon occurred. 
A still further investigation led to the discovery that the virus used in ino 
lating the animals, and which is procured from the lung a cow suffering fr
