very strong argument in favor of the immediate slaughter of all 
the animals in an infected herd that have been exposed, as well 
as of those visibly affected. It is evidence of the usual results 
of half measures, resulting merely in postponing the inevitable, 
after a useless and costly delay, which could have been avoided. 
This case also furnishes abundant proof of that which has been 
so often contended, and in this country confidently denied, 
namely, that animals may be infected with this disease and liable 
to communicate it to others, and yet show no outward signs of

Endurance of Arab Horses. —The oft-quoted endurance of 
Arab horses lias received recent confirmation of the strongest 
kind. The officer commanding the Nineteenth Hussars, in the 
unfortunate campaign for the relief of Khartoum, has published 
some interesting memoranda in regard to these animals, which 
were the mounts of his regiment during that expedition. These 
were Arab stallions, about eight or nine years of age. Out of 
350 horses, only 12 died of disease during a hard campaign of 
nine months. For four months of the time the weather was very 
trying, food was limited, and during the desert march water was 
very scarce. On the final march made by the troops, 155 of 
these horses were fifty-five hours without a drop of water and
