Notes: 

     Johnston was the first to offer the Widal test, using dried blood, on a public basis.  He routinely argued against withholding diphtheria antitoxin pending bacteriologic diagnosis.  He was also the driving force behind the APHA Committee of Bacteriologists to the Committee on the Pollution of Water Supplies.  Johnston recommended that the committee draw up procedures for the study of bacteria in a uniform manner.  The committee made recommendations for standardizing media and culture techniques. 

     Johnston was one of the first to employ the Widal test as a diagnostic tool in 1896, and the first to show that it could be used on dried blood, and not merely blood serum.

     At the 1900 meeting of the SAB, he presented a talk on "An American Bacteriological Journal."
