vi. lappuse - So certainly, if a man meditate upon the universal frame of nature, the earth, with men upon it, the divineness of souls excepted, will not seem much other than an ant-hill, where some ants carry corn, and some carry their young, ami some go empty, and all to and fro a little heap of dust.
78. lappuse - Servetus possessed of the way by which the blood passed from the right to the left side of the heart was in advance of his time, and a step beyond that reached by Galen.
26. lappuse - ... have endeavoured to discover the truth, by the examination of the structure and the observation of the phenomena of life without torturing living animals. It is too common a belief that, in physiology, experiments on living animals are the best and surest way of pursuing an inquiry, although it is certain that the supposed issue of experiments is as much affected by the preconception as the process of reasoning can be. The experimenter on brutes is not to be called a philosopher because he goes...
25. lappuse - In what follows, as in what has preceded, I have endeavoured to discover the truth, by the examination of the structure and the observation of the phenomena of life without torturing living animals. It is too common a belief that, in physiology, experiments on living animals...
27. lappuse - It would be arraigning Providence to suppose that we are permitted to penetrate the mysteries of nature by perpetrating cruelties which are ever against our instinctive feelings. I am therefore happy in believing that the examination of the natural structure and the watchful observance of the phenomena of life, will go further to give us just notions of physiology than dissections of living animals.

27. lappuse - ... is but a poor manner of acquiring fame, to multiply experiments on brutes, and take the chances of discovery. We ought at least to try to get at the truth without cruelty, and to form a judgment without having recourse to torture. At all events, it is our duty to prepare for experiments upon living animals by the closest previous application of our reason, so that we may narrow the question, and make it certain that advantage shall be gained by the experiment.''!
47. lappuse - Whence is it that the artery is enlarged all the way down the arm ? I am of opinion that it is somehow the consequence of the blood passing so readily from the artery into the vein, and that it will always so happen in such cases. That it is not owing to any particular weakness in the coats of the artery, like that in a true...
32. lappuse - But although it were admitted that the force of the heart is sufficient to carry the blood thrpugh the whole extent of the arterial system* it cannot be made to account for the inequalities which we observe in the force of the arterial actions. It cannot account for increase and diminution of secretion; for sudden and partial growth; for wasting and decay of parts, while the general body is vigorous. It will not account for an organ being plentifully supplied with circulating blood one hour, and...
