CONCLUSIONS. 



It is advisable to estimate the blood diastatic activity in all cases where the 

 urine diastatic activity is being examined, and especially in those cases which 

 give a urinary diastase figure towards the lower limits of normality. 



It would appear that the diastatic concentration factor would serve as an 

 additional confirmatory test to MacLean's urea concentration test, as the figures 

 obtained for both tests in healthy and pathological cases were in general 

 agreement. 



I am indebted to Prof. J. A. MacWilliam and to Prof. H. MacLean for much 

 kindly help and suggestion, and to Dr. W. Brander, Medical Superintendent, 

 Hackney Infirmary, for permission to examine numerous cases.
