Let each nii'iuluT of the class work out one of the foll(.\viii.<jf prohlciiis 

 in ck'tuil uiid present results to class: How woul.l y<>u j.lau to take sole 

 care of a case of tyi'li«>i"l (to injure ai^ainst catchinj,^ it yourself or 

 pennittini,^ it to sjn-ead to others)? of tuberculosis? of .UTij.j.e? of 

 pneumonia? of diphtheria? of dysentery? of erysipelas? of leprosy? 

 of scarlet fever? of measles? of pella-ra? of smallpox? (Refer t(» 

 best available manuals for trained nurses.) 



What pi^ecautions would you take if you were a ty].hoid carrier? 

 if you were a dii)htheria carrier? if you were infected with tubercu- 

 losis? if you had the grijipe? if you had tonsillitis? if you had a cold? 

 Is the Schick reaction used in your district to test immunity to clij-h- 

 theria? Look n[> use of Widal reaction in detection of typhoid carriers. 



I^Iake out a complete list of diseases of man and other animals for 

 which we have reliable antitoxins, vaccines, or liacterins. Discuss their 

 use in your district and get reports from those who have tested them. 

 File this list in the laboratory and note changes and growth from 

 year to year. 



It is estimated that in 191 4 diseases of farm animals caused damage 

 to the amount of $212,0()(),()()(). Can the class work out plans of coojh 

 eration by which any of these diseases may be brought under control? 



Compare the merits, for various purposes, of different disinfectants, 

 antiseptics, and germicides on the market. Study especially the liome 

 and dairy use of the hypochlorites. Get the reports on all these things 

 from the United States Public Health Service, Washington, D.C. 



Collect and discuss national, state, and local quarantine and health 

 laws and ordinances. 



Visit as many of the local dairies as possible. Obtain the official 

 score cards from your dairy inspector and study the scoring he has 

 given. Are the dairymen included in the scoring? 



In the liu'htof all vou have learned alumt bacteria, discuss the prob- 

 lem of washing dishes properly. Slioiild we banish the "common dish- 

 towel " along with the "common roller towel." .Make plate tests for 

 nuudx'rs of bacteria in ''dishcloths," in "dish-towels," in "dishwater," 

 and on the dishes after different methods of washing and drying. How- 

 do these tests compare with Wm^i- made on dishes after actually boiling 

 for five minutes in the rinsing water? after treating with hypochlorite^ 

 in rinsing water, without wiping? 



It is being claimed that spread of infections in families, especially 

 of colds, grippe, and tonsillitis, might be greatly reduce-d by steriliza- 

 tion of dishes. Can the class find a test for this in their ..wn homes?
