an important subject. He (Mr. Taylor) bad pleasure in according 
bis meed of praise to the essayist, although he differed from him in 
opinion. He considered vomica in the lung tissue to be produced 
by softening of tubercle; he recognised two distinct causes for its 
production, first from a poisonous condition of the blood, secondly 
as a result from an attack of pneumonia, in which disease, if the 
congestive stage passes unrelieved, hepatization will follow, to 
which, if unchecked, softening and vomicae succeed. Who, in our 
present imperfect state of knowledge, shall say what is the primary 
cause acting in the production of blood diseases? Who can feel 
satisfied that miliary tubercle is due to arrestation in the capillary 
circulation, or to deposition into the pulmonary parenchyma? On 
the other band we can recognise more clearly the ordinary causes of 
simple inflammation attacking the lungs. Mr. Taylor considered 
the case described by Messrs. Morgan and Heves to he more nearly 
related to the pneumonic than to a blood poison type of disease. Treat- 
ment should depend upon the stage the disease may be in and the 
symptoms presented ; he advocated pure fresh air and plenty of it, 
extreme quietude, agents to act upon the liver, taking especial care 
to avoid catharsis, stimulants judiciously administered, of which he 
held carbonate of ammonia in high esteem, and in some cases the 
application of blisters. 
Mr. Greaves believed the most valuable medicine we possessed 
for the treatment of typhoid diseases was carbonate of ammonia. 
He considered that this agent not only exerted a beneficial influence 
upon the liver, but also upon most, if not all other secerning glands. 
He did not advocate irritating embrocations to the skin ; but attached 
great importance to the application of a stimulating liniment to the 
ears as a means of determining a flow of blood to the head, and 
thereby promote increased circulation in the brain, enabling it to act 
with more vigour. 
Mr. Reynolds was in favour of the free admission of pure air, and 
warm clothing to whatever part of the body it was applicable, in all 
cases where there is a tendency to coldness of the extremities and 
skin accompanied with difficult respiration, as adjuncts to determine 
the blood from accumulating in the vital organs. He much pre- 
ferred the application of oil of cantharides to mustard, ammonia, 
turpentine, and other exciting irritative liniments. He had repeat- 
edly noticed that in all cases where a blister had produced 
copious effusion an equivalent subsidence on the more important 
symptoms succeeded. 
Mr. W. C. Lawson coincided with the essayist upon the benefit 
derived from the use of hot rugs, and thought that not unfrequently 
more good than harm resulted from the application of irritating 
liniments in arousing the subdued vital energies of animals affected 
with typhoid diseases. 
Mr. Elam said he had much experience amongst horses newly 
introduced into this town for omnibus work from Ireland, and had 
seen many cases (in horses which on arrival he had passed sound) 
of disease proving fatal in ten to fourteen days, the post-mortem exa-
