642 IDENTITY OF PLEURO-PNEUMONIA AND RUBEOLA, 
milk, are diminished as the fever increases. The skin of the 
lower animal about this period becomes dry, and tightly 
bound down to the subcutaneous textures. It is not merely 
the staring coat usual in cattle in most illnesses; but it is 
a peculiar dry, hard, wiry state, and has been noticed by 
some to be so in blotches. This condition or symptom is 
noticed at the same period as would correspond to the ap¬ 
pearance of the eruption in man. At this time red spots or 
patches may be often perceived on the mucous surfaces of 
the mouth and nostrils, as is not uncommonly witnessed in 
rubeola ; and an offensive odour comes from the mouth, pre¬ 
cisely alike in both cases. The cutaneous rash has often been 
noticed, and it was at one time supposed to be a form of 
eczema, of which the pleuro-pneumonia was a sequela. At 
this early period of the fever, neither auscultation nor percus¬ 
sion is of much avail. By the former the dry sonorous rale 
of ordinary bronchitis may be detected along the windpipe 
and in the bronchial tubes. Every medical man knows how 
closely these agree as among the general symptoms of rubeola. 
I am aware that the distinctness of the eruption is not men¬ 
tioned by several systematic writers, who seem to include it 
under the ordinary account of the coat; and if we bear in 
mind the thickness of this hairy covering, we readily under¬ 
stand how a mere efflorescence of the cutis passed unnoticed, 
for it is not like varicella, or variola, while in scarlatina the 
intense redness of the mouth and fauces could not fail to be 
seen, and to lead to the detection of the rash in that fever. 
But the strongest proof of the presence of an eruption is the 
copious furfuraceous, or bran-like, dust in the coat, owing to 
the desquamation of cuticle. In this the diseases strongly 
correspond. The state is not seen in every case, certainly, 
neither of rubeola nor of pleuro-pneumonia, because the rash 
must be very freely out in the first instance, or the noticeable 
desquamation does not take place. Again, the disease in 
animals is often very mild; just as in cases of rubeola the 
symptoms may be so moderate, as not to attract .much no¬ 
tice. Some animals suffer very slightly, and it is only when 
the disease runs on to the formidable second stage with 
severity that it arrests attention. Thus it was ascertained, by 
one inquiry in France that eighty-three per cent, recovered, 
and seventeen per cent, died, of all taken ill, and that of the 
former proportion some were very little affected. I cannot 
tell whether this bears any proportion to the mortality from 
rubeola, nor whether it corresponds to the fatality of pleuro¬ 
pneumonia in this colony; but I may remark that it proves 
that the latter disease is not always so terribly fatal in propor-
