long-standing myxedema with arterial changes and hypertension, true renal 

 pathology supervenes. This stadium, however, does not enter into the 

 present consideration. Thyroid failure is usually associated with a mild 

 secondary anaemia. All three of the endocrinopathies tend to exhibit 

 lymphoid bloods though in varying degrees of frequency. The pituitary 

 alone shows a slight eosinophilia, a possible diagnostic point where the 

 numerous non-endocrine causes are ruled out. 



In table 5 will be considered two important observations, namely, the 

 respiratory and the carbohydrate metabolism. The several quantitative

and directional variations are most helpful in the formulation of a differ- 

 ential diagnosis. 



While functional failure of all these glands produce a lowering of the 

 oxygen requirement, that of the thyroid is far greater than the modest decre- 

 ment shown by the other two. In making this statement, it is assumed 

 that the basal rate is actually measured. Unfortunately, the observation 

 is peculiarly sensitive to subversive agencies — chief among which is the 

 patient — and the confidence in the record, so freely granted because it is 

 determined mechanically, is frequently unwarranted. It is no common 

 experience in the speaker's laboratory, where the test is repeated day after 

 day for purposes of education with the nervous patient, to have a final
