This and That

In the context of British Inland Waterways, "narrow boat" refers to the original working boats built in the 18th, 19th, and 20th centuries for carrying goods on the narrow canals (where locks and bridge holes would have a minimum width of 7 feet (2.1 m)). The term is extended to modern "narrowboats" used for recreation and occasionally as homes, whose design is an interpretation of the old boats for modern purposes and modern materials.

Eyes are organs that detect light, and convert it to electro-chemical impulses in neurons. The simplest photoreceptors in conscious vision connect light to movement. In higher organisms the eye is a complex optical system which collects light from the surrounding environment; regulates its intensity through a diaphragm; focuses it through an adjustable assembly of lenses to form an image; converts this image into a set of electrical signals; and transmits these signals to the brain, through complex neural pathways that connect the eye, via the optic nerve, to the visual cortex and other areas of the brain. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in molluscs, chordates and arthropods.

A farm is an area of land, including various structures, devoted primarily to the practice of producing and managing food (produce, grains, or livestock), fibres and, increasingly, fuel.

In the British Isles the first pillar post boxes were erected in Jersey in 1852. Roadside wall boxes first appeared in 1857 as a cheaper alternative to pillar boxes, especially in rural districts. The first boxes to be painted red were in London in July 1874, although it would be nearly 10 years before all the boxes had been repainted.

The most recent innovation in the zipper's design was the introduction of models that could open on both ends, as on jackets. Today the zipper is by far the most widespread fastener, and is found almost everywhere, installed on clothing, luggage, leather goods, and various other objects

Physically a nose is an organ on the face. Anatomically, a nose is a protuberance in vertebrates that houses the nostrils, or nares, which admit and expel air for respiration in conjunction with the mouth
