ease found its way up the Delaware to
Riverton, a short distance above the city of Philadelphia. A
cattle-dealer, named Ward, turned some cattle into a lot, adjoining
which several others were grazing. The residents of this place are
chiefly the families of gentlemen doing business in the city, many of
whom lost their favorite animals from this destructive malady.

The first case occurring at this place, to which the author's attention
was called, was a cow belonging to Mr. D. Parrish, which had been
exposed by coming in contact with Ward's cattle, had sickened, and died.
An anxiety having been manifested to ascertain the cause of the death,
the author made an examination of the animal, which, upon dissection,
proved the disease to be a genuine case of the so-called
pleuro-pneumonia. This examination was made August 20th, 1860, at the
time of the Massachusetts excitement. Two cows, belonging to Mr. Rose,
of the same place, had been exposed, and both had taken the disease.
His attention having been called to them, he placed them under the
author's treatment, and by the use of diffusible stimulants and tonics,
one of these animals recovered, while the other was slaughtered for an
examination, which revealed all the morbid conditions so characteristic
of this disease.

The next case was a cow belonging to Mr. G. H. Roach, of the same place,
which had been grazing in a lot adjoining that of Mr. Parrish. This cow
was killed in the presence of Charles Wood, V.S., of Boston, Mass., and
Arthur S. Copeman, of Utica, N. Y., who was one of a committee appointed
by the New York State Agricultural Society for the purpose of
investigating the disease. Both of these gentlemen having witnessed the
disease in-all its forms, as it appeared in Massachusetts, were the
first to identify this case with those in that State.

Upon opening the cow, the left lung was found to be completely
consolidated, and adhered to the left side, presenting the appearance
usual in such cases. As she was with calf, the lungs of the foetus
were examined, disclosing a beautiful state of red hepatization.

The author's attention was next called to the herd of Mr. Lippincott, a
farmer in the neighborhood, who had lost several cattle by the disease;
but as he had been persuaded that treatment was useless, he abandoned
the idea of attempting to save his stock in that way. From Riverton it
soon spread to Burlington, some ten miles farther up the river, where it
