Secondary nucleation of magnesium sulfate and of potassium aluminum sulfate was observed by subjecting a single solute crystal to a momentary jet of supersaturated solution. The solution contacting the crystal was transferred to a region of greater subcooling in which nucleating crystals were observed. Nucleation of magnesium sulfate was very sensitive to the level of subcooling at the parent crystal and recalled the critical character of homogeneous nucleation. Nucleation of alum showed no evidence of such critical behavior.
