REVIEW— FIELD’S VETERINARY RECORDS.

rectness of the Professor’s doctrine, and, by drawing the atten- 
tion of the members of the Society to the point in question, to 
lead them to a more attentive observation of it in their practice ; 
and the result has been, we think we may add in justice to the 
memory of the deceased, that the two diseases, pleurisy and 
pneumonia, are not now confounded in the manner they formerly 
were. 
H epatirrhcea, or hemorrhage from the liver , next 
engaged John Field’s attention. He read a paper on the subject 
to the Veterinary Medical Society in 1830, stating it to be a 
disease confined to the horse alone, rarely to occur under ten 
years of age, and then, in such subjects as are in appearance 
remarkably healthful and fat, and that are good feeders, and in 
constant work ; and as the disease is not manifested before “ the 
whole or part of the liver is irreparably destroyed, but little can 
be expected from the aid of the veterinary art, save the prevent- 
ing the abuse of those depletive measures, particularly vene- 
section, to which non-veterinary persons are apt to have re- 
course in all kinds of ailments, and by which patients of this 
class have been a little sooner hurried off.” Such cases, for- 
tunately for the credit of our art, are by no means of frequent 
occurrence; though the extensive practice of John Field brought 
several of them under his notice. 
Purpura Hemorrhagica. — On this subject we have, in 
the work before us, " a rough outline, apparently,” as the editor 
informs us, “ for some future paper.” The subject is one of a 
most interesting description, and, if we mistake not, even at this 
distant day from its first introduction, to many veterinarians is 
still a novel one. We think we are not erring when we assert, 
that the scarlatina , of which Mr. Percivall first made public 
announcement in The Veterinarian, in the year 1834, and 
which, in his Hippop athology, he has since also denominated 
“ morbillous disease,” is the disorder here described. We have 
no desire to quarrel about names, though in such a case as the 
present we deem more than ordinary caution requisite in the 
choice of one ; but we feel it our duty to say, after taking all 
the phenomena of the extraordinary disease in question into con- 
sideration, we think Mr. Field’s the more appropriate appella- 
tion : and we say this with full conviction, that neither to pur- 
pura nor to scarlatina, as those diseases commonly occur in man, 
does the disease in the horse completely correspond. Mr. Field’s 
“ Outline,” as far as it goes, in itself excellently descriptive, is 
elucidated by cases (at pages 47, 214, 217, 233) on which, it 
seems not unlikely, it was originally founded. 
Intus-susception and Pleuro-pn eumonia constitute the 
subjects of two other skeleton papers; and though they are, as
