septaria

It is imbedded in a mass of septaria, weighing upwards of 150 pounds, with two fine specimens of fossil wood; and was obtained in digging for cement stone, about five miles from Harwich, in three fathoms water, where, as a mass of stone, it had been used for some time as a stepping block.

Caen stone was brought for the stone dressings to windows and doors, parapets and groins, but masses of septaria found on the shore and in the neighbouring marshes were utilized with such good effect that the walls have stood the attacks of besiegers and weathered the storms of the east coast for more than seven centuries.

I observed that the septaria and larger masses of shale which the bed contains, bear, on roughly-polished surfaces, in the line of their larger axes, the mysterious groovings and scratchings of this period, -- marks which I have never yet known to fail in their chronological evidence.

The pebbles, like those of the boulder-clay of the northern side of the Moray Frith, are chiefly of the primary rocks and older sandstones, and were probably in the neighborhood, in their present rolled form, long ere the re-formation of the inclosing mass; while the shale and the septaria are, as shown by their fossils, decidedly Liasic.

Here we find its counterpart in this large mass of stone; only the clay here, mixed with a portion of lime is petrified, and the fissures filled up with carbonate of lime; thus forming the septaria, or cement stone.

It is thinly charged with rolled pebbles, septaria, and pieces of a bituminous shale, containing broken Belemnites, and sorely-flattened Ammonites, that exist as thin films of a white chalky lime.

I have septaria of this kind, in which, besides pyrites, iron-ore, calcareous spar, and another that is ferruginous and compound, there is contained siliceous crystals; a case which is not so common.

But there are other septaria of iron-stone which seem to have had a very different origin, their cavities having been formed in cooling or congealing from an ignited state, as is ingeniously deduced by Dr. Hutton from their internal structure.
