MICROBE'S 



CHALLENGE 



By 

 FREDERICK EBERSON, PH.D., M.D. 



This is a story of vital interest to 

 every individual. For the scientist 

 and physician it presents a permanent 

 record of the progress made during 

 very recent years in preventive medi- 

 cine. For the student, it illustrates 

 how by perseverance, accurate pro- 

 cedure, and meticulous observation, 

 the great discoveries of science are 

 made. For the general reader, it pro- 

 vides a cultural education that touches 

 nearly every phase of daily living. 



Of very great interest is the account 

 of the work now being done by con- 

 temporary scientists and the impor- 

 tant problems that are on the verge of 

 being solved. We like to know of 

 these benefactors of humanity living 

 and working in our day. 



It behooves every true student to 

 read Dr. Eberson's inspiring book, to 

 live once again the tense moments of 

 epoch-making discoveries, and to be 

 reminded that many fertile seeds still 

 lie dormant with the floodlight of to- 

 day's amazing progress playing upon 

 them, awaiting only the ."seeing eye" 

 of a searcher for the truth.
