182 MICROBES AND THE MICROBE -KILLER. 



been a close student, not of medical books, but of Nature. 

 With the most powerful microscopes obtainable he se- 

 cured microbes from nearly every disease known to> 

 medical science. He went further than this. In his own 

 laboratory he constructed a wonderful instrument for 

 photographing these microbes. It is too complicated to 

 be described here, but the results it accomplishes will 

 give an idea of what it will do. Upon a glass slide he 

 can place a drop of blood. A few moments later he can 

 show you a photograph five inches wide and seven 

 inches long, showing the blood corpuscles looking nearly 

 as large as silver dimes. But do not think that is the 

 photograph of the whole drop of blood. The lens is sa 

 powerful that it only covers a hundredth part of the 

 drop of blood. To photograph the whole drop of blood 

 would produce one hundred similar- pictures, or one con- 

 tinuous sheet of photographs containing one hundred 

 separate photographs, each seven inches long and five 

 inches wide. 



Thousands and thousands of the microbe photographs 

 Mr. Eadam has made. He could secure no one compe- 

 tent to do the work, so he has done it all himself. In 

 his laboratory he has many prints of microbes taken 

 from every disease known to medical science. At the 

 World's Fair last summer he had hundreds of photo- 

 graphs of these different kinds of microbes, ranging 

 from the microbes which eat into the lungs and cause 

 tuberculosis to the microbes which eat into the scalp, 

 cause dandruff, and destroy the hair. Such is the man- 

 ner in which "Mr. Radam has proven what he once held 

 only as a possible theory. 



In his main office at No. 1288 Broadway, near Thirty- 

 fourth street, Mr. Radam has a large collection of these 

 pictures and the finest microbe laboratory in the world. 

 There you can see in photographs all the microbes which 

 destroy life. If you prefer to see them in reality instead 

 of in photographs, there are revolving tables loaded with 

 microscopes, under the lenses of which are living mi- 

 crobes. In different bottles he keeps the different mi-
