fish. Linnaeus thus states it : “ Mane in braraa corta mensae 
apposita etiamnum vivam vidit nobilissim. Dorn. Nic. Rosen, 
Colleg. nul. Clarissim.” It is painful to see the ingenuity of 
such a philosopher as Dr. Darwin exerted in the attempt to ex- 
plain the existence of this. He supposes the existence of 
the fasciolae hepaticae to proceed from a too dilute state of 
the bile, and the inactivity of the absorbent vessels of the liver. 
But this is a conclusion without premises ; for, although the 
theory may account for the general morbid state of the animal 
in whose liver these insects are found, yet he forgets to inform us 
how the ova or embryo of the insect got into the liver ( Phytolo- 
gia, 4to. p. 338.) Omitting the many curious facts on record, 
which might be adduced as further elucidations of the proposition 
I have stated, more especially that inserted in the New Medical 
and Physical Journal of London, for October 1811, in which 
an eruption, having every distinctive mark of small-pox of the 
most favourable kind, was attended with a discharge of maggots, 
not only from each pustule, on being opened, but also with the 
urine and feces, — a case well authenticated ; and also that re- 
lated by Dr. Chichester, of Bath, of haematemesis, occasioned 
by, and attended with, a discharge per anum of many hundred 
nondescript larvae, extremely active and voracious, capable of 
living without inconvenience (not at all affected by either) in 
alkohol, port-wine, and oil {Med. and Surg. Journal of Edin. 
vol. vii, 326); I say, omitting these and many other facts, 1 
shall content myself with the following very extraordinary case, 
communicated to me a few years ago, at Bath, by a gentleman 
of great respectability, who witnessed himself the phenomena, 
and whose brother was the object of it. When this gentleman 
was between fourteen and fifteen, he suddenly, and without any 
apparent cause, lost his appetite and strength ; he became ema- 
ciated, had hectic flushings, and the hair of his head fell off. 
Together with these symptoms, he had uniformly a painful sen- 
sation across the stomach. In short, he was considered to be in a 
decline, and Dr. Addington, the father of the present Lord Sid- 
mouth, who attended him, put him on a milk diet, &c. In this 
state he was, one day, in the presence of his father and his bro- 
ther, my informant, suddenly seized with violent convulsions, in 
which his stomach was thrown into a spasmodic state. In one 
of the efforts consequent upon this state, he threw up three 
frogs, small but lively, besides a number of tadpoles, or animals 
resembling tadpoles. From that moment his recovery com- 
menced, and was soon established. The frogs were put into 
water, but they became languid, and seemed out of their ele- 
ment : they were then put into milk, in which they recovered,
