A double-disector method for obtaining estimates of the number of particles inside other particles, illustrated by an estimation of the average cell number in a glomerulus, has been developed. The method is suitable for paraffin-embedded tissue because it does not require knowledge about the section thickness. Most importantly, the estimate is absolutely unaffected by tissue shrinkage. The average number of cells in a human glomerulus is 2850 whereas in rats it is 580.
