LIFE-SAVING. 



BY DBLOS FALL, ALBION, MICH. 



Sanitaeians are in the habit frequently of advancing claims in 

 regard to the practical value of their woik, resulting, they say, 

 in a great lessening of sickness and the actual saving of many 

 lives. For example, in a carefully prepared paper, read before 

 the Sanitary Convention at Vicksburg, Dr. Baker, secretary of the 

 Michigan State Board of Health, gave official statistics and evi- 

 dence, which he summarized as follows: — 



'■ The record of the great saving of human life and health in 

 Michigan in recent years is one to which, it seems to me, the 

 State and Ideal boards of health in Michigan can justly 'point 

 with pride.' It is a record of the saving of over one hundred 

 lives per year from small-pox, four hundred lives per year saved 

 from death by scarlet-fever, and nearly six hundred lives per 

 year saved from death by diphtheria — an aggregate of eleven 

 hundred lives per year, or three lives per day saved from these 

 three diseases ! This is a record which we ask to have examined, 

 and which we are willing to have compared with that of the man 

 who ' made two blades of grass grow where only one grew be- 

 fore. ' " 



It has occurred to the writer that even scientific workers look 

 upon such statements with a large degree of allowance. They 

 can be demonstrated, however, as the following will illustrate: 

 The table below is compiled from reports of local health officers 

 to the secretary of the State Board of Health relative to the 

 cases of sickness and deaths from diphtheria in Michigan during
