![Some facts also suggest the possibility of an antagonism between the thymus and thyroid in their relationship to the nervous system. The thyroidal secretion directly or indirectly has a stimulating influence over the cerebral functions, as is shown by their undeveloped condition in cretinism and their degeneration in myxoedema and after thyroidectomy, and also by the effects following the administra- tion of thyroid extract in cases of cretinism. There are reasons, too, for believing as pointed out by Freund and Horsley,^ that the activity of the thyroid gland is increased when active changes are taking place in the sexual system. On the other hand, during hibernation, when the thymus attains its greatest size,“ the cerebral and sexual functions are suspended, and in infancy are undeveloped, but undergo rapid develop- ment at puberty, when the thymus finally disappears. These facts suggest a functional relationship between the different ductless glands, and lead one to think that disease may result from disturbance in the balance of their internal secretions, which might be remedied by suitable animal extracts, REFERENCES.
