duced two examples, first, the utter failure of the very ingenious 

 theory of Dr Murray to explain, on ordinary chemical pnnciples,

 which the colourless cells were greatly increased in number. This 

 condition he had called leucocythemia, which was always associated 

 with enlargement of the spleen or other lymphatic glands, a circum-
