of individual suspicious eases which come to the sanitarian of their 

 own accord. Munson 7 has given this method particular attention in 

 the Jinny with astonishingly favorable results. 



Since the incnliation time of the disease is about two weeks, the 

 exclusion of children from school need not exceed this period. 



SCARLET FEVER 



(Scarlatina) 



The etiology of scarlet fever, like that of measles, is still obscure. 

 Streptococci have been found with striking regularity in the throats 

 of scarlet-fever patients, and a large number of investigations have 

 seemed to furnish evidence for the etiological relationship of these 

 microorganisms with the disease. According to von I/mgelsheim, 

 Crooke as early as 1885 demonstrated the presence of streptococci in 

 the cadavers nf sea Net-fever victims. Uaginsky and Somrnerfeld * in 

 1900 examined a number of scarlatina cases with reference especially 

 to streptocoecus infection, and reported the presence of streptococci 

 in the heart's blood of eight patients who had died after a very acute 

 and short illness. They expressed the belief that the acuteness of the 

 illness and the rapidity of death in these cases precluded the possi- 

 bility of the streptococci being merely secondary invaders. A large 

 number of other observers have expressed similar opinions, but we 

 can not, as yet, justly conclude that streptococci are actually the 

 etiological agents of this disease. 



Class" in 1S!M described a diploeoccus which he cultivated from a 

 large number of scarlat ina patients and with which he was able to pro- 

 duce exanthemata and acute fever in pigs. Subsequent investigations 

 seem to show that (lass was really working with a streptococcus. 



IVroser, 1 " working in Kse.herieh's clinic, has recently reported the 

 very favorable influence upon the course of scarlet fever of polyvalent 

 streptococcus antisera. r rhis is not really very strong evidence in 

 favor of the streptococcus etiology of the disease, since then 1 is, of 

 COUrse, no doubt that streptococcus infection complicates the disease,
