THE MICROSCOPE. 29 
Board of Health, is one of the most elegant in make-up and 
valuable in contents of the many which have come under our 
observation. Aside from the valuable reports from the health 
officers or inspectors in various parts of the State, a number of 
papers of great importance from the pens of some of Pennsylvania’s 
most distinguished scientists and physicians, are included, A 
pocket in the back cover contains an excellent map, showing the 
mortality from diphtheria in the city of Pittsburg, and a table 
relative to consumption, illustrating a paper by Dr. Wm. Pepper.
