& Co.’s. Prof. Law answered that letter, and both of these will be 
found in toto in this number of the .Review. 
Lesions found at post mortem are said to be characteristic of 
the disease, and the question at stake, whether or no those found 
at Blissville or in the other animals killed bv the authorities since, 
were the true lesions of contagious pleuro-pneumonia, seem to be 
the problem which European authorities were called upon to settle. 
A letter said to have been written to an eminent American 
pathologist (?) by Prof. Williams has been published, which tends 
to criminate the diagnosis made by Profs. McEaehran, Law and 
others, besides ourselves, and to show that after all, all the wri¬ 
tings, reports, orders and sanitary measures were all useless, as no 
contagious lung disease existed here. 
Prof. Law, though much pressed by the work which has been 
placed in his hands, and which he carries with so much energy, 
and whose result will never be forgotten, still finds a moment to 
answer Prof. Williams. These we print also. 
Now, as we desire to be charitable towards every one, it 
seems to us that this letter of the eminent professor of Edinburgh 
has been written by him without a thorough acquaintance with 
the truth , and that he has been misguided by one who has never 
been present, as far as we know, at any of the post mortems 
made either in Long Island or any other place by order of the 
officers appointed by the Governor of our State. 
It is with much regret that we find Prof. Williams in the 
equivocal position where he has placed himself in relation to the 
Blissville cattle, as stated in his letter, for this is taken as a 
powerful argument by the few whose interests it serves, and with 
which they are trying to save themselves from an ignoble drown¬ 
ing. In such a professional position and standing as the one held 
by Prof. Williams all over the English speaking world, an erroneous 
statement is not excusable, and for this reason ought not to have 
been made without thorough evidence of its correctness. 
Whether the Ontario cattle had epizootic pleuro-pneumonia 
or not we do not pretend to say. The professional standing of 
the Professor ought to be sufficient guarantee of the certainty of 
his diagnosis, though we understand he was the only one among
