ancc of illness. Milcli cows especially fall early victims to 
the malady^ and in many cases the serons membrane of the 
cliest is found to be scarcelv aflected_, the force of the 
disease having been directed principally upon the pul¬ 
monary tissues^ which, after death, present appearances 
closely allied to hepatization from acute inflammatory 
action. There seems to be less disposition to effusion of 
lymph than in the ordinary form of pleuro-pneumonia ; the 
symptoms also bear a very close resemblance to, if not an 
absolute identity with, epizootic typhoid pneumonia. This 
disease is particularly prevalent in the-vicinity of Dublin, 
and many animals in the early stages of it are to be met 
with in the Dublin old Smithfield Cattle Market. In this 
market store stock is purchased each Thursday for exporta¬ 
tion to Great Britain, and, as we are informed, no sanitary 
supervision whatever is exercised over the sales. 
This disease of the lungs is now supplemented by an out¬ 
break of the foot and mouth disease in Ireland, which, sin¬ 
gularly enough, was introduced two days before the passing 
of the Order of Council forbidding importations, except 
from Spain and other uninfected countries. A state of 
things, therefore, exists which makes it absolutely necessary 
that means be at once taken by the executive to pre¬ 
vent further injury being done the British farmer through 
the Irish cattle exports. He has a right to demand that at 
least a strict supervision over the Dublin market shall be 
instituted, and that Portal examination, which proved so 
beneficial during the cattle plague, shall be forthwith re¬ 
established.

THE PHYSIOLOGICAL EFEECTS OF LIGHTNING. 
Phofessor Pepper’s great induction coil at the Polytechnic 
has afforded Dr. Richardson an opportunity of carrying out 
a number of extremely interesting experiments on the effects 
of powerful electric shocks on the animal body. In a lecture 
delivered at the Polytechnic, Dr. Richardson summarised the
