HYDATIDS WITHIN THE BRAIN, &c. 
that, against this and verminous disorders in general, all pro¬ 
phylactic means are comprised—in guarding against humidity ; 
in giving wholesome and substantial food, and even some tonic 
condiments ; in pure air; in banishing from the breeding fold 
the delicate and weakly, and especially such rams as have al¬ 
ready got a sickly progeny. 
My uncle, M. Yvart, late Professor of Agriculture at Al- 
fort, remarked, that one winter that he fed his flock on cinque¬ 
foil he had less staggers among them than in any other. 
The Marquis of Sainte-Fere has recently published, in the 
third Report of the Society for the Improvement of Wool, that 
since he has made use of the apparatus for disengaging oxygen 
gas into his sheep-sheds, it is very rare fcrr him to hear of one 
with staggers. 
M, Girou de Buzaseingues, in a paper on the staggers 
in sheep, read before the Royal and Central Society of Agricul¬ 
ture, on the 1st of December, 1824, and inserted in the Annals 
of Trench Agriculture, January, 1825, expresses himself as fol¬ 
lows :—I have put into practice my mode of prevention. I have 
fed my flock better and given them more exercise : I have had 
them driven on the mountains of Aveyron, where the salubriety 
of the air, and the extent of the pasturage, induce them to take 
exercise; often by playing and skipping, and where the diversity 
of the herbage invites them to stray about to cull the sweetest 
food. I have spread about salt mixed with soot. By such 
regimen have I strengthened my sheep, and the consequence 
has been less staggers among them : however, the malady has 
not altogether disappeared, a circumstance I am not surprised 
at, since I do not expect to eradicate that in a day from an 
organized body which is the product of many years; still, I 
reckon on its gradual decline, and by perseverance to get quite 
rid of it.^’ This author acknowledges the unsuccessfulness of 
the curative means ordinarily employed, which he urges as an 
additional reason for adopting the preservative measures he re¬ 
commends or analagous ones ; there being every probability 
that the number of staggered sheep will be lessened thereby, 
besides insuring the health and prosperity of flocks in general.
