P. 282) has been published by the inventor, describing the practical trial at the Cockle Creek Works.
COCKLE, in zoology, a mollusc (Cardium) of the class Lamellibranchia.
The two valves of the shell of the common cockle are similar to each other, and somewhat circular in outline.
By means of this muscular foot the cockle burrows rapidly in the muddy sand of the sea-shore, and it can also when it is not buried perform considerable leaps by suddenly bending the foot.
In other respects the anatomy of the cockle presents no important differences from that of a typical Lamellibranch.
After a few days, when the mantle bearing the shell valves has developed so much as to enclose the whole body, the young cockle sinks to the bottom and commences to follow the habits of the adult..
The usual size of the cockle in its shell is from I to 2 in.
The common cockle is regularly used as food by the poorer classes.
The cockle is liable to the same suspicion as the oyster of conveying the contamination of typhoid fever where the shores are polluted, but as it is boiled before being eaten it is probably less dangerous.
The industries include brewing, shipbuilding, copper and iron-founding, carriagebuilding and fellmongery; there are boot factories, engineering works, biscuit factories and smelting works at Cockle Creek.
Weeds are very numerous (about 125); and some, notably the sand-bur (Solanum rostratum) cockle-bur, and tumble-weeds among indigenous, and the Russian thistle (Salsola tragus) and purslane among non-indigenous species, are agricultural pests.
It seems needless to give references to the voluminous discussion in newspapers and periodicals concerning the authenticity of a wax bust of Flora acquired in 1909 for the Berlin Museum and unfortunately ascribed to Leonardo da Vinci, its real author having been proved by external and internal evidence to be the Englishman Richard Cockle Lucas, and its date 1846.
