25. s∼)132 nm spheres at comparable volume fractions in an analogous confined geometry at an equivalent screening length, for example, the late time morphology consists of large isolated rafrs of the 2 μm spheres in coexistence with a dilute fluid of single 2 μm spheres. The details of the culster-size distriution function for this scenario will be reported elsewhere (E. K. Hobbie, unpulished).
26. The clustering criterion specifies a minimum separation between adjacent large-sphere centers. In a previous publication (Ref. 18) this distance was taken as the position at half maximum of the nearest-neighbor peak in g(r). The distance used here is the halfway point between the first maximum and the first minimum in g(r). Although the results obtained for the average cluster size and the total number of large spheres cluszered are slightly different, the functional form of the time dependence is the same.
27. Over the course of a typical experiment, peripheral large spheres leave and enter the region defined by the fixed field of view, although the total number of large spheres contained in the field of view at any given time deviates by less than 2% from the time avarage value.

29. -nb. Distinguishing logarithmically slow growth from true steady state behavior is always difficult in both experiments and somulations. and future measurements will be designed to better address this.
