SCALES OF THE SOLE 189 



This discovery concerns alike doctors, nurses, 

 and parents. The mortality among infants 

 is enormous, and is commented upon almost 

 daily in our papers. Here, apparently, . is 

 one cause of at least one of the fatal 

 diseases. Fuller's earth must be abandoned 

 altogether as a dressing for open wounds, how- 

 ever produced, or its sale in an unsterilised 

 form be prohibited. 



The illustration is from a photo-micrograph, 

 showing the ' drumstick 7 bacilli amplified 

 to 1,000 diameters. As already stated, the 

 objective used was a T ^th oil immersion. 



Scales of the Sole. 



The imbricated arrangement of the scales 

 covering the skin of the sole makes this fish 

 of more than ordinary interest to students with 

 a microscope. The illustration (Fig. 63) is 

 from a negative of 36 diameters.
