squamous appearance with cornification; in this context these cells would be indistinguishable from skin squames. The other study that we have found of interest has been the estimation of the size of clusters found in various stages of gestation and maturity in scrapings taken from the skin of the axillw of infants. This is a very difficult and subjective test but it is our impression that as the infant matures the size of these clusters increases, apparently to a maximum in postmaturity. We therefore feel that not only the numbers and types of cells, but also their development into sheets and clusters, together with the presence of flecks of debris and globules, are important parameters in assessing maturity.
