Using a new analysis method, we search for narrow energy band, millisecond flares in gamma-ray bursts. This type of emission may occur if burst continuum spectra are composed of multiple short-lived black bodies. We use time-tagged count data from the BATSE Spectroscopy Detectors to determine the probability that a pair of counts came from the same energy band. If burst energy spectra are composed of many short duration black bodies, the average correlation between counts should be larger when the counts are separated by small time intervals. We discuss how the correlation between counts is calculated and apply this method to three bright bursts. We find no evidence that millisecond, narrow energy band flares compose a significant fraction of the emission in these bursts.
