ficial circulation may be checked up and variations in blood 

 pressure may be anticipated. 



Conclusions. 



The need of a simple clinical measure of cyanosis has long- 

 been felt, not only by surgeons and anaesthetists, but by physicians 

 who have under their care pulmonary and cardiac cases. 



It is contended that sub-oxydation or oxygen unsaturation of 

 the total circulating blood is abnormal and imperils the life of 

 the patient. 



There appears to be a large unexplored field in the physio- 

 logical limits of oxygen unsaturation. This field includes ob- 

 stetrics. 



By simple laboratory methods the two extremes of complete 

 cyanosis and complete oxygenation have been secured. 



The exact color value of these extremes has been permanently 

 recorded by the help of the Munsell system of color notation. 



Intermediate gradations of these extremes have been secured 

 by mechanical means, so that a scale is available. 



The resulting scale, the hsemoxometer (oxyhemoglobino- 

 meter) is a positive basic measure of the oxyhemoglobin con- 

 tent of the blood under observation. The opacity presented by 

 the ringer nail and mucous membrane has been studied and close- 

 ly duplicated. 



The hsemoxometer is offered as a simple clinical measure of 

 oxygen unsaturation (cyanosis), basically correct, in practice, 

 approximate. 



In submitting this original device, the writer is convinced that 

 it has a sphere of usefulness scarcely second to that of the 

 hsemoglobinometer.

Allergy to cow's milk in infants with severe malnutrition. 



By OSCAR M. SCHLOSS and ARTHUR ANDERSON 



[From the Children's Hospital, Boston, Mass.] 



There is much evidence to indicate that under certain con- 

 ditions the intestinal tract of infants is permeable to slightly 

 altered or unaltered protein.
