Light rays Purify Food

: $ xrcw IMvOC'KSS TO DEKTKOY POISONOUS GERMS. Porfessor Gorham, of tilie nlk",mistry research department of the Hrown rnivcr.sity, I'.S.A., lias discovered ii, method. by which mi!!: fish and meat may bp efficiently sterilised )>y tin; means of ult"'iviolent rays. ITo claims that) tilo use of the rays will pi event the possi) i-y of epidemics through the "medium ol tain-ted food, and will readv th-e contraction of consumption, typhoid and ptomaine poisoning through food impurities impossible. It will consequently mllow Governments tio dispense with elaborate tceslt.s for detecting impurities, -Jii'e. alter thorough saturation by il).'; rays all micro-orgamisms are destroyed. His discovery, lie state.-, counts of a method of applying the rays, particularly to milk, meat an<l fish, so as to kill all microbes and miKe it'he foods treated perfectly pur-:. The light from Sir William Crooros' tmbos i.s allowed to play directly on the foods, causing complete ste.':lisn f.ioti. Professor Gorhams greatest diflicult v Ivns been witih the treatment- of milk. Sterilisation can be effected bv allowing: the milk to flow over CVookes' tubes, but unless it is pnr-?-fully handled thereafter it can become .impregnated with bacteria. It is impossible to sterilise >nik after it is hi'ittled, because tho ravs do not effectively pass through glass. Professor Gnviliain says that tho new method of spilling milk—adopted in American cities- in bottles made 'of oastrboard treated wii'tli oariTin •oiiviaites tilio difficulty, as the rn >*=: penetrate the pasteboard.
