CONTAGIOUS CATTLE DISEASES IN YORKSHIRE. 337 
diseases, being about one in 1000. In 1871 3 in the East 
Riding, the losses from foot and mouth disease were, 18 
from pleuro-pneumonia, and 20 from foot and mouth dis¬ 
ease, out of 72,406; in the North, 57 from pleuro-pneumonia, 
and 61 from foot and mouth disease, out of 140,220; in 
the West, 81 from pleuro-pneumonia, and 113 from foot 
and mouth disease, out of 217,088; making a total loss from 
both diseases of 340 out of 429,714, being a rather more 
favorable return than for 1870, in spite of the widespread 
outbreak of foot and mouth disease in the autumn of that 
year. On the whole, therefore, I cannot but hope that the 
Acts are working satisfactorily, when 1 compare this loss with 
the losses which occurred under my own personal observation 
before the days of the cattle plague, when the restrictions at 
that time in force very nearly freed us from all other cattle 
diseases. 
I am truly yours,
