X' by their form and larger size, some being 4 sq. mm. in area. These are for the most part near the periphery of the section. With a lens, too, some variations in color of the ground mass from light to dull- gray can be seen. Among the nickel-poor ataxites, to which, as can be seen later by reference to the analysis, this group belongs, the etched surfaces of the meteorite most resemble those of the Locust ; Whether Farrington intended microscopic examination of the meteorite cannot be ascertained, but had he done so he doubtless would have observed additional features and perhaps would have modified some of the results he obtained. For reasons given later,. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Roy, Sharat Kumar, 1897-1962.
