Twenty five low redshift quasars have been monitored for several decades atfive near- and mid-infrared wavelengths to detect rapid variations which wouldindicate that a nonthermal component was present in the "10 micron bump". Suchvariability has apparently been detected in several radio loud quasars and inthe radio quiet quasar PG1535+547. In addition, the structure function ofPG1226+023 shows that an apparently periodic component is present in itsnear-infrared emission.Comment: AAS LaTex, 33 figures in 2 postscript files, AJ, accepte
