EFFECTS OF NOXIOUS VAPOURS. 
I can imagine that the present specimen was produced 
somewhat in the same way, and had it not been removed 
would have acted as a foreign agent, and if pressed upon to 
any extent by the saddle or harness might have produced 
inflammation of the surrounding parts. It was judicious, 
therefore, on the part of Mr. Longman, to remove it. The 
tumour measured two and a half inches long, and one and 
three quarters wide. In its central and thickest part it 
was one fourth of an inch thick, gradually becoming thinner 
towards its edges. 
The case, in many points of view, is interesting. 
Facts and Observations. 
ECZEMA EPIZOOTICA. 
A few months since we recorded the fact that eczema 
epizootica was prevailing to a serious extent among the cows 
in the metropolis, and that many animals had fallen victims 
to its malignancy. We have now to inform our readers that 
the disease has reappeared in a severe form in the metro¬ 
politan county, and that it is also again proving very destruc¬ 
tive to the lives of cattle in several of the surrounding 
counties. It will, then, be seen that the laws regulating the 
extension of this disease require even a more searching in¬ 
vestigation than they have hitherto received. 
EEEECTS OF NOXIOUS VAPOURS. 
In the minutes of the evidence taken before the select 
committee appointed by the House of Lords during the last 
session, (( to inquire into the injury resulting from noxious 
vapours evolved in certain manufacturing processes,’' the 
state of the country round St. Helen's is described as 
“ one scene of desolation; you might look round for a mile, 
and not see a tree with any foliage on whatever.” The acid 
vapours have done it all. As these drift around, trees lose 
their leaves, the tops decay, the bark hardens and becomes 
adherent, and, after a struggle for life, which lasts a year or 
two, the trees perish. Apples have nearly disappeared from 
the neighbourhood. Where twenty bushels used to be 
gathered, only a measure or two can be got now. Hedges
