people believed  \nplants in the foreseeable future takes on the aspect that about all they had to do was to take the right  \ncombination and amounts of vitamins to cure what-ever ailed them.Current research in the field ofnutrition,however,is bringing to light the factthat the right amino acids(and enough of them,aspresent naturally in foods),a comparatively recentdiscovery in nutrition,are more essential for phys-ical well-being than vitamins.  \nof magic or necromancy in the mind of the personwho is unfamiliar with the scientific method.Sen-sational claims for particular products that over-play or distort scientific findings are in part respon-sible for the layman's feeling that all that is neededfor the solution of a certain problem is for one ormore white-coated scientists to get together andmeditate on the matter,and,in due course,theywill be able to pull a solution,or perhaps a greatnew scientific discovery,out of a hat.The illusionof ease and simplicity of doing scientific work ifonly a big modernistic laboratory and a half milliondollars worth of instruments is at hand is fosteredby the facility with which a person without tech-nical training is able to operate such complex de-vices as a miniature camera,a high-fidelity radio,or television set.All he has to do is to press a but-ton,turn a switch or dial and,presto,he obtainsresults that have taken years,perhaps

ammonium phosphate as pro-viding some sort of magical protection for the teeth.The researches in this field are,however,still in-complete and many experiments and observationswill need to be made before it can be known withcertainty whether the ammoniated dental productsare effective at all in preventing or inhibiting tooth  \nThe importance of the role played by vitaminsin human nutrition has
