![He must ever remember, that a congested conditio! of the vessels of the head and eyes, is one of the com- mon dangers to which sedentary men and deep thinker: are subject. He must, therefore, never conform to any of the fashions which may increase this tendency. The cravat, for instance, should sit loosely about the neck I Every part of the dress should be so easy as not to make- undue pressure upon the abdominal organs, even thou«l. it be at the sacrifice of some of the modern, false notionr of taste. It will be at the risk of much good health anc > good eye-sight, if men of studious habits permit thai' tailors of the present day to be the supreme arbiters o: j taste. 4. Let the student, for the same reasons, carefully avoid a confined condition of the bowels. Nothing ex <] erts a more unsalutary effect upon the eyes than this| It lays the foundation for obstructions of the abdomina circulation, and consequent congestions of the head anci) eyes. Hence the dull headach and heavy spirits of the* \ constipated man. Hence the cloudy vision, so frequenthj attendant upon this state of the system. Hence also thffl motes and various anomalous deviations from perfect vwj sion, sometimes amounting to actual loss of sight, whicH present themselves in the costive man; partly from con-| gestion of the vessels of the eye, and partly from its inti;| mate sympathies with these distant organs.* Costiveness is the peculiar danger of sedentary men 1 It is one to which their habits, especially their neglect o J exercise, renders them exceedingly liable. Its injurious operation upon the eyes is so great, that it cannot bill avoided with too much care. It has undoubtedly unfit ? ted the eyes of many scholars for continued labour; ancj not unfrequently constituted the principal cause that ha i numbered others among the blind. The great pressure and straining that the constipatec j man is obliged to make in evacuating the bowels, pro ] * The bare mention of the fact, that the tunica conjunctiva, j membrane covering the surface of the eye, is a mere continuatioi 4 of that which is spread over the internal surface of the whole ali I mentary canal, may serve to impress these truths on the mind. 30](https://iiif.wellcomecollection.org/image/b21633903_0036.jp2/full/800%2C/0/default.jpg)
