Neverthelftw, it muat be admitted that to reoogniie thia was a great advance upon the view that the ipleen had no impor- tant function, and that thia was shown by the removal of the organ without change in the Ani- mal'a economy. But to believe that there are no such changes, and to have clear jnoof of it, are two difltoent things. Asamatter pf fact, closer study does show that in some animals there are alterations in the lymphatic glands and bone-marrow, which organs are undoubtedly manu- facturers of blood- cells. These changes , ara unquestionably compensatory, and that other similar ones owresponding to comparatively unknown functions of the qileen have not as yet been discovered is owing likely to our fkdlures rather than their real sbsence. We dwell for a mo- mv<fnt on this, because it illustrates the danger of the sort of rear sonii^g that has been amdied in the case of this and other or- gans; and it shows the hnportanoe of reedgniiing the force o| the general principles of biology, md also the desiraMlity of refraining fiwn drawing conclusions that are too wide for the i^remises. In every department of physiology it must be mfwe and mm recogniwd that what is true of (me group of animals is not necessarily true of another, <sr even <rf other individuals, though the differences in the latter case are of oouxw usually leas marked.
