The followingbeautiful diagram of the lymphatic system (Fig. 100), by Pro-fessor Dal ton, will serve for impressing the matter.

In conclusion: That there is automatism in the lymph ves-sels is not only logically true, but the fact is scientificallyascertained.

Moreover, they are not syn-chronous with the action in the heart or with respiration, oreven with one another, possessing independent action. k In the large ceratoplirys cornuta two pairs of ischiadiclymph-hearts have been fo
