I also discovered that the webs of the little spiders in the road, when saturated with moisture, as they were from the early fog this morning, exhibit prismatic tints. Every thread of the web was strung with minute spherules of moisture, and they displayed all the tints of the rainbow. In each of them I saw one abutment of a tiny rainbow.
The conclusion seems but natural, that in the one case the siliceous exuviae have been left in their original form; in the other dissolved chemically, and aggregated on the common principle of chemical affinity into nodules of flint, probably concentrating, in every instance, upon a piece of decaying organic matter, as has been the case with the nodules of ironstone in the earlier rocks, and the spherules of the oolite.
A variation of the thyroid in the direction of increased secretion was probably responsible for the first land animals. Under the microscope, as in the test tube, the thyroid shows remarkable and unique features. Closed spherules lined by a single layer of cells enclosing a gelatinous material known as colloid, which stains deeply with acid dyes, comprise the units of its architecture.
"Mother of God, what is it then? magic?" "No, only base metal." But here, Concho, emboldened by Wiles's experiment, attempted to seize a handful of the glistening mass, that instantly broke through his fingers in a thousand tiny spherules, and even sent a few globules up his shirt sleeves, until he danced around in mingled fear and childish pleasure.

Peter sandstone of the upper Mississippi valley, are composed so entirely of polished spherules of quartz that it has been believed by some that their grains were long blown about in ancient deserts before they were deposited in the sea.
This primitive form in the upper convex part was a structure of contiguous globules or spherules, and each spherule was a joining together of those more minute, and each of these in like manner of those most minute. It was thus of three degrees. In front, in the flat part, a kind of delineation appeared for a face.
