well-marked symptoms, all having occurred in the town and 
neighbourhood of Cardiff. 
Treatment .—Being satisfied as to the undoubted existence 
of the Ascaris lumbricdides, and that this parasite, existing 
in large numbers, was the exciting cause of the disturbance, 
I at once endeavoured to effect their speedy and complete 
removal. For this purpose, in every case, I prescribed as 
follows: 
Aloes Barb, pulv., 5j; 
Ant. Potass. Tart., 5iss; 
Perri Sulpli., 5ij; 
Potass. Nit., 5ss. 
Misce, fiat bol. j.“ 
One of these balls was ordered to be given every night and 
morning until the bowels became relaxed. The diet con¬ 
sisted of bran, linseed, and oats, all well steamed, and given 
warm. The result of this treatment has invariably been 
that, after the fourth or fifth dose has been given, a complete 
expulsion of the worms has taken place ; in fact, I have never 
yet found any other means required, or this at all necessary 
to be repeated. 
I may mention that the large number of nearly six hun¬ 
dred of these “ disturbers of the horse’s peace ” were com¬ 
mitted to “safe keeping” inCase 1, and from four to five 
hundred of them in Case 2; and many of them measured in 
length from eighteen inches to over two feet. In all the 
cases I have seen here the numbers of the worms have 
been enormous, though not always so large in size as in the 
two cases quoted. 
Having relieved the poor beast of these annoyances, I next 
turn my attention to the general state of the animal, and 
when great prostration and debility present themselves, I 
prescribe : 
Ipt) Zingib. Rad. pulv., 5ij; 
Gent. Rad. pulv., ; 
Liq. Am. Acet., ^iv. Misce, fiat haust. 
To be given in warm gruel every night and morning for two 
or three days, followed up with any ordinary mineral tonic. 
I prefer Ferri Sulph., given in half-drachm doses, twice a 
day, in the food, which latter should be liberal. This usually 
completes the cure. 
Remarks .—It appears somewhat remarkable that these 
parasites should be found so generally among the horses, 
both of light and heavy kinds, in this neighbourhood ; and I 
think the cause worth an inquiry into. Can it be the nature
