     The stormer viscometer measures the viscosity of a
     fluid by measuring the time taken for an inner cylinder
     in the mechanism to perform a fixed number of revolu-
     tions in response to an actuating weight.  The viscome-
     ter is calibrated by measuring the time taken with
     varying weights while the mechanism is suspended in
     fluids of accurately known viscosity.  The data comes
     from such a calibration, and theoretical considerations
     suggest a nonlinear relationship between time, weight
     and viscosity, of the form `Time = (B1*Viscos-
     ity)/(Weight - B2) + E' where `B1' and `B2' are unknown
     parameters to be estimated, and `E' is error.
