16 WHY WE STUDY SCIENCE 



The final proof came when two English physician 

 Dr. Manson and Dr. Warren, allowed themselves to 1 

 bitten in England by mosquitoes which had been sei 

 from Italy, but which had been previously fed on the bloc 

 of a person having malaria. Neither of these men ha 

 had malaria previously, but eighteen days after they we: 

 bitten, they both came down with the disease. This 

 an excellent example of how scientific method is applu 

 in the discovery of new facts important to mankind. A 

 we have to do to escape malaria is to be sure that malari 

 mosquitoes do not bite us. 



A study of the method of science. If we study th 

 scientific method more fully, we find, first, that the scientii 

 has a reason for trying to solve a problem. He thinks ov< 

 this problem, and finally gets clear in his mind just wtu 

 he wants to find out. He has then fixed his problem 

 His next step is to try to find out some method or methoc 

 of solving it. This he does by thinking over various waj 

 in which he can attack it. He finally fixes on some metho 

 which he tries out by means of experiments to test wheth< 

 his theories are correct. He may and often does ha\ 

 to perform hundreds of experiments before he is satisfie 

 that he has a correct solution. This was the case with D 

 Ross as he worked over his problem of how the malarii 

 mosquito played a part in giving the disease to peopL 

 At length, after he has satisfied himself that he has th 

 solution to his problem, he must then put it to a practice 

 test. This was done, you remember, by the English do< 

 tors who allowed themselves to be bitten by the mosquitoe: 

 and thus proved that mosquitoes transmit malaria. 



The method of science useful in daily life. This metho 

 of science which we have just described should become
