The Story Of The Liver

liecent inv-estigations have sliown that Bclentlsts are just begimung to unüerstand the human body. In that oigamlsm no orgam playa a more vital pturt than the liver, about vvhich Prof. Audrew Wilson ,of the UniverBlty ol Ediiilmr.nl). has -n-ritten a popalar article fckr the May Harper's, onilo(lying in it the resulta of the ateBt scicntific reseaTCh. As cvery peí txm has more or lees trouble -vvlth liis oí1 her liver ive a-epriut an extract fi-om the article, believinig all ou readers will be interes-ted : The arautomieal faets regarding the lir are easily appreclated. By way of a. rationa! imderstanding of the Jivtr's work it is necessary to beoome icíjuainted witli the liver's buüd. It s the biggest organ la öur body, weiOhi(ag, as it does, befcweem tbree fine! four poiind1. lts color is of a , chcclate brown, tianged somewhat I wiül a buvnt-umber hue. Lying to the riglrt of the stamacli, it is sheltered i,nder the lower ritos and below the muiacle (or "diapin agni') -whicli eepaa-ates the cliest ironi the body's lom-r aity. Cane: above, it is hollowed out below, and its right side is tliick and rounded, ii. opposition to its tlün left border. Solid in substanee, we'. liad the Hver marbed off into iire unequal pa-rts, or dlvisions, or "lobes," of whicJi the ilgïit lobe is the lai-gest, the left left lobe aiext in point of Bize. Now Itbis big glaaid, as regaipde its esssdit.iai structm-e, is iound to be comiioied of cells. Everywhere we find the essential elemente iof a living body to osisist oí these microscopic units ■tho nature oï -rhich it is necessary appreciate, especially -witli referciice to tlie liver's woipk aud duties.
