THE MARSHES OF THE TEIKE.

rienced butchers know well, by the volume of the spleen, in 
what countries the animals they slaughter were bred. Two 
veterinarians, who have reported on the subject, suggest, for 
the extirpation of the scourge, that the watering places be 
done away with, and a regular system of cultivation esta- 
blished. 
From what we have said about the nature of the sub-soil, 
we believe we might with advantage unite drainage to the 
hygienic measures proposed. The influence such practice 
has exerted in ameliorating the sanitary condition of rural 
populations and domestic animals in England and Scotland, 
constitutes a fact upon which much stress is laid by the 
sanitary reports of Great Britain. Intermittent fevers, and 
the aqueous cachectic, have almost entirely disappeared from 
the county of Perth since drainage has been practised there 
upon a large scale. 
There exists an ultimate correlation between paludian dis- 
ease and the culture of the soil. In countries wherein agri- 
culture is prosecuted to perfection, and the soil, thus to say, 
has no rest, and whose population is compact, intermittent 
fevers are of rare occurrence. Whereas, w here the earth is 
left uncultivated, and becomes covered with spontaneous 
luxurious vegetation and thick forests, deboisement is practised 
on a large scale, and the human and brute inhabitants are 
but thinly sow n, malaria is favoured. 
Paludian affections are not at all times, then, confined to 
veritable marshy places, though the effluvia, whatever be 
their origin, are not the less impregnated with their deadly 
activity towards both men and brutes. — Rec, de Med, Vet

EPIDEMIC AMONG POULTRY. 
M. Brice, sugar- re finer, at Champigneulles, near Nancy, 
lost in four days, of the disease, 125 hens, 80 poulets, 
and 3 turkeys. The symptoms observed were, a notable 
alteration in the voice, its tone becoming less clear and 
sonorous — graver, having a catch in it, like a plaint repeated 
at short intervals. This is the earliest sign of attack. Its 
walk is constrained, appearing painful and automatic ; the 
hen stops as though seized with a sort of languid wearisome 
prostration ; soon it utters a plaintive cry, walks on again, 
and again stops, and so continues to act for an hour or an
