 awaits him, and fortunate is he if he escapes in 

 these advanced days of scientific discovery, when 

 so many of our mortal ills are shown to be de- 

 pendent upon the malignity of hovering germs, of 

 microbes, bacteria, and bacilli. 



Let us be thankful we have at least escaped the 

 notice of one of this insidious throng, and are

 is its course! To-day a pert and gladsome inno-
