but the greater number are undoubtedly contained within 

 the cells. They are also, found in the spindle-shaped con- 

 nective tissue cells of the granulation tissue, in endothelial 

 cells, and in the walls of blood vessels. They are for the 

 most part confined to the leucocytes and connective tissue 

 elements, but a few may be seen in the hair follicles and

glands of the skin. Occasionally one or two may be found 

 in the surface epithelium, where they probably have been 

 carried by leucocytes, but that position is, on the whole, 

 exceptional. They also occur in large numbers in the 

 lymphatic glands associated with the affected parts. In the 

 internal organs liver, spleen, etc., when leprous lesions are 

 present the bacilli are also found, though in relatively fewer
