The most recent study has been made by Hayasi (78), who finds that the calcareous lamellae which form the sclerodermites are formed by secretions of the calicoblasts and that the latter are not themselves calcified.

1943, Thomas Wayland Vaughan, John West Wells, Revision of the Suborders Families, and Genera of the Scleractinia, page 32:

The same is true of the sclerodermites of Holothuroidea but it is not true of other echinoderm microfossils, such as echinoid pedicellariæ and microcrinoids.

1963, University of Glasgow. Geological Department, Papers - Volume 25 -, page 153:

Where the sclerodermites are arranged in a linear series making an almost continuous ( commonly zig-zag, Fig.38) line of centres of calcification, the resulting trabecula has a circular cross-section equal to the equatorial section of a single sclerodermite.

1972, Carbonate Sediments and Their Diagenesis, page 26:

Observations made during microprobe analysis and with SEM indicate that calcitized sclerodermite centers are concentrated in horizons parallel to growth banding.

1995, Susan J. Gaffey, Victor P. Zabielski, Charles Bronnimann, “Roles of Organics and Water in Preneomorphic and Early Neomorphic Alteration of Coralline Aragonites from San Salvador Island, Bahamas”, in H. Allen Curran, Brian White, editor, Terrestrial and shallow marine geology of the Bahamas and Bermuda, page 240:

The aspicular, aragonitic skeleton of a living sphictozoid (Neocoelia) lacks the sclerodermite microstructure in other aragonitic skeletons indicating a significant difference in the pattern of crystallization. The absence of entrapped siliceous spicules in this sponge does not appear to be the cause for the lack of sclerodermites since in Merlia sclerodermites are present but entrapped spicules are not ( Hartman and Goreau, 1970).

It applies, indeed, solely in its present state to the capillaries of the saurial and batrachoid reptiles; but there is every reason to believe, that the same arrangement takes place in the mammated class of animals.

1832, Marshall Hall, Art. II: A Critical and Experimental Essay on the Circulation of Blood: The Edinburgh Medical and Surgical Journal, page 167:

An idea, not undeserving attention, has been announced on this subject by M. Reynaud, who, observing that a similar anatomical arrangement is found in the batrachoid amphibia, or frog family during the whole period of existence, infers, though not very confidently, that it may be applied to explain the arrangement of the vascular system now under consideration, by referring it to the earliest periods of intra-uterine life in the Mammalia.

1841, David Craigie, Art. XII: Instance of Obliteration of the Aorta beyond the Arch: The Edinburgh Medical and Surgical Journal, page 461:

It gave, therefore, additional evidence of the existence of air-breathing vertebrata at the period of the deposition of the coal-strata, and extended the known geographical range of the batrachoid reptiles of the carboniferous epoch.

1853, The Literary Gazette, London, page 114:

There is no doubt but that the Batrachoid fishes deserve at least the rank given them by Dr. Gill, coördinate with the Trachinoidea, the Gobiodea, or the Blennioidea (as arranged by Gill , for I do not accept Mr. Regan's inclusion of the Ophidioidea and Zoarceoidea in that group).

1923, Edwin Chapin Starks, The Osteology and Relationships of the Uranoscopoid Fishes, Stanford University Press, page 267:

tetanise (alternative)

Thus, on tetanizing an only slightly irritable nerve, applied to the deriving cushions by its longitudinal and transverse sections very near to the exciting electrodes, with the alternating currents of the Inversor arranged so that its closing value in the unit of time is brought as near as possible to unity, frequently we get only a trace of negative variation, or none at all, or even a positive deflection; but, repeating the experiment several times, we always get a feeble negative variation.

1868, Charles E. Morgan, Electro Physiology and Therapeutics:

There is, in short, little doubt that the constituent of mammalian muscle which liberates carbon dioxide on prolonged boiling, is the same as that which is decomposed in tetanus and rigor; for if muscles are tetanized or made rigid, while at the same time opportunity is offered for th escape of the carbon dioxide which is known to be generated in those processes, the yield of dioxide on subsequent boiling is reduced to a mean of 20 or 30 vols. p. c. instead of 100.

1880, Arthur Gamgee, A Text-book of the Physiological Chemistry of the Animal Body:

This tetanizing effect on muscles is most pronounced in frequencies from 15-150 cycles per second.

dead zone

LL-Q1860 (eng)-Flame, not lame-dead zone.wav

Planet Earth Research this year discovered that humans have created at least 50 ‘dead zones’ (zones where there is no oxygen) in the sea through pollution, and have extinguished other species at 1,000 times the natural rate in evolution.

It is only really in the past decade that science has begun to tell us that the man-made changes now occurring in the oceans – from acidification to overfishing to the growth of dead zones – represent some of the greatest threats to life on Earth.

2012, Charles Clover, ‘Up To Our Necks’, Literary Review, number 399:

By the time the Mississippi enters the gulf, its current has been transformed into a conduit for chemical nutrients, and this enriched current stimulates massive blooms of phytoplanktons. Consequently, it forms a dead zone the size of Massachusetts (7,900 square miles or 20,461 square kilometers) every summer, which has existed since the 1970s and supports almost no life beyond phytoplankton and bacteria.

If one of these caterpillars is irritated, it will bend back its head and shoot out a curious forked organ from the segment just behind the head. This osmeterium, as it is called, is yellow and is forced out by muscular action and by the pressure of the blood; at the same time a sickly over-powering odour of lemons is given off — the smell has also been likened to that of rotten pineapples...
Most of the cocktail ants are tree dwellers, making their nests under the bark, in hollow branches, or in carton nests attached to the branches. The carton nests are more or less spherical in shape, black, and they vary in size according to the size of the colonies. They are made of chewed vegetable fibres mixed with the secretion of the maxillary glands of the workers, which blackens the material and acts as a cement. The walls are thin and papery and the interior consists of irregular cells, like a coarse sponge. If the wall of one of these nests is broken open, the workers swarm out, with their tails in the air and their repugnatorial glands exposed..
