PNEUMODES is a species of asthma; and the affection is connected with the lungs as is the case in asthma. The attendant symptoms are common, and there is but little difference; for dyspnœa, cough, insomnolency, and heat are common symptoms, as also loss of appetite and general emaciation. Moreover, the disease is protracted for a time, yet not longer than one year; for, if the autumn begin it, the patients die in the spring or in the summer; or if the winter, they terminate their life towards the autumn. Old persons also are at certain times readily seized; and being seized with rigors, it requires but a slight inclination of the scale to lay them on the bed of death. All labour in particular under want of breath; pulse small, frequent, feeble. But these symptoms are also common to asthma; they have this as peculiar; they cough as if going to expectorate, but their effort is vain, for they bring up nothing; or if anything is forcibly separated from the lungs, it is a small, white, round substance, resembling a hailstone.See in particular Galen, de loc. affect. iv.; Alexander, vi. 1; and Paulus Ægineta, Syd. Soc. Edit. t.i. p. 474. The thorax is broader, indeed, than natural, but not altered in shape, and is free from ulceration; yet, though the lungs be free from suppuration, they are filled with humours, which are, as it were, compacted. The intervals of the paroxysms in this affection are greater. Some, indeed, die speedily of suffocation before anything worse is transferred to the general system. In other cases the affection terminates in dropsy about the loins, or in anasarca.
