  A third parameter, in addition to luminosity and rate of brightness decline,
derived from the spectra of transients is suggested as a means of more
accurately classifying objects in outburst. Principal component analysis of the
spectra of transients is suggested as the best way to determine the third
parameter. A model is suggested for novae ejecta that is based on ballistic
ejection of an ensemble of globules. The distribution in sizes of the clouds
should determine basic characteristics of the ejecta, including the short term
brightness fluctuations of novae in decline and the location of dust formation.
