368 A FEW OBSERVATIONS ON THE MORBID 
puration commences, beginning in the hitherto blocked-up 
air-cells. The granules or tubercles also now become soft, 
like soft cheese or cream, and partially or imperfectly suppu¬ 
rate; or else abscesses form within their interspaces, in the sof¬ 
tened solidified parenchyma, the suppurating air-cells operating 
as sorts of centres from which maturation extends; and this 
process, once established, becomes a rapid one. Indeed, when 
we come to consider what horses are the more common sub¬ 
jects of pneumonia, horses young and vigorous, and in high, 
or at all events plethoric, condition, under circumstances of 
much preternatural excitement, we have no reason to express 
surprise at the rapidity with which pleural and pulmonary 
diseases in particular, of all descriptions, are apt to run their 
course. The following table of abstracts of cases, recorded at 
length in my Sick Register, will illustrate this:—
