Received: August 7, 1991




An examination of the Mira variable HS Aquilae using recent Maria Mitchell Observatory plates reveals that the period has become shorter than the 267-day period given by Harwood in 1962.  A constantly decreasing period is favored over an abrupt change.  The rate of change is approximately -0.17 +_ 0.01 day per year.
