![in view, the study of the mere volume of air inhaled or expelled, will afford no satisfactory explanation of the laws regulating the evolution of heat, which is precisely his view. Many illustrations of a redaction in the tempera- ture of the body, from a disturbance in the natural rela- tions between the inspired air and the quantity as well as the quality of the blood brought to the lungs are given in my writings. The following passages bear directly on this subject: “ The modifications in the properties and distribution of the blood cannot, however, he justly ascribed to the derangement of the respiratory function solely, when that derangement is of long continuance, since, in that case, they are partly produced by disease of the different organs which contribute, either directly or indirectly, to the production of chyle : for if this fluid is deficient in its ordi- nary nourishing qualities, the arterial blood will necessarily expe- rience a deterioration, although the conditions of the respiratory organs, essential to the chemical changes of the blood, may at the same time be only slightly affected.”* “The chemical changes in the lungs may be considered as rendering the blood nutritious, by imparting to it oxygen, and ex tracting from it carbon, but if it has become exceedingly impover- ished, from abundant excretions, the inspired ah- will not modify it to the usual extent, or in other words, will be incapable of supplying the vital properties which have been gradually dissipated by the in- ordinate activity of the excretory functions.]■ “ If the vascularity of the lungs be diminished in advanced life, from the obliteration of a portion of their vessels, it is quite clear, that they are not then so well calculated to expose the sanguineous fluid to the influence of the inspired air, as in infancy and childhood, when these vessels are much more numerous and healthily consti- * Principles of Medicine, p. 302. f Page 352.
