THIS apparatus is designed to ascertain the amount of 

 haemoglobin in either a diseased or a normal condition of 

 the blood. It was devised by Prof. E. von Fleischl, and 

 patented by Carl Reichert, of Vienna. (See Fig. 3). This

little instrument, the Hsemometer, is the result of a need felt by 

 physicians and scientists of having an instrument which will give 

 a quantitative judgment (analysis) of the value and function of the 

 haemoglobin in the circulating blood. It was further necessitated 

 by the inapplicability of the methods thus far prescribed for this 

 purpose to the cases encountered by physicians ; and, finally, it 

 arose from the hope of advancing our physiological and clinical 

 knowledge by rating the per cent, of haemoglobin in diseased 

 human blood. 



The Haemometer cannot be used either by daylight or by 

 the electric light, and only by the light of oil lamps, candles, and 



gas.
