No experimental proof has hitherto been obtained that stimulation of the cerebral organs lying above the vaso-motor centre, and which include those possessing the function of thought, ever paralyzes this centre; but, as it is only by such paralysis that cerebral conditions can induce dilatation of blood-vessels, it must follow that no _experimental proof_ at present exists that stimulation of the brain ever does cause such dilatation -- that is, ever does become a cause of hæmorrhage.
The proof of this lies in the words _ex ou_ just below; not _ex ôn_ (_ouranôn_) but _ex ou_ (_politeumatos_): I can find _no proof_ of the assertion (Moulton's
