It is a remarkable fact that Dr. Gregory, of Edinburgh (1753-1821), in bis once highly-valued “Conspectus MedicinceC writes thus uncertainly of the lesion in Hemiplegia being on the opposite side to the paralysed limbs, a fact which had been well known to the ancients*:—

“Fertur, et sane plurimorum jam medicorum observa- tionibus confirmatur, latus adversum ab eo in quo cerebri vitium est sic resolvi.” (Chapter xii., section 382).

Heberden, it is true, contributed observations which were not unworthy of Sydenham or Hippocrates, but his work, like theirs, was purely clinical. It was not until the close of the Great War that scientific medicine made a fresh start. Its progress has since mainly depended upon the application of new methods of observation by the stethoscope, the test tube, the microscope, the clinical thermometer, and the ophthalmoscope.
