and neck* the body increasing in size gradually from the an¬ 
terior extremity to the widest portion. The posterior ex¬ 
tremity is rounded, not pointed as in F. hepatica. Its color 
is slate blue on the ventral surface, due to the intestine being 
visible under the skin. The skin, apparently smooth to the 
naked eye, is seen on examination to be covered with minute 
spines, much smaller than those covering the body of F. he¬ 
patica. The genital pore is situated midway between the 
mouth and ventral acetabulum. The intestine is plainly visi¬ 
ble under the skin and consists of two main branches arising 
from the termination of the oesophagus, and passing directly 
downward in the centre of the body, being separated from 
one another by a very narrow space, giving off in their course 
numerous branches which divide and subdivide, making the 
intestinal arrangement appear more complicated than either 
that of F. hepatica or F. gigantea. Each final subdivision ends 
in a coecum. The specimens from which this description is 
taken have been in alcohol four years, and are not in condi 
tion to give accurate anatomical details. On some future 
occasion I may have an opportunity to describe its structure 
more definitely. 
ACUTE DYSPNEA. 
Translated by Richard Middleton, A.B., D.V.S., Philadelphia, Pa. 
Dyspnoea in general, when occurring in our domestic 
animals, is seldom an object for therapeutic interference. If 
we exclude the so-called “ heaves ” of horses, which only de¬ 
mands attention from its forensic significance, the dog only, 
in his better situation, remains for our consideration. 
The usual variety in the dog develops itself insidiously in 
the course of his life, unnoticed by the owner; it is the con¬ 
sequence of obesity, of cardiac weakness and dilatation and 
of fatty metamorphosis of the heart; or it is met as a sequence 
of diseases of the chest and abdomen. The question then has 
to do with a chronic dvspncea, with a difficulty of respiration 
which increases with the lapse of months and years. 
The remaining variety is the subject of this discourse. 
This afflicts an animal as an idiopathic lesion, independent of
