An illustration of an anamirta cocculus branch with flowers. Anamirta cocculus is an Southeast Asian and Indian climbing plant. Its fruit, Cocculus indicus, is the source of picrotoxin, a poisonous alkaloid with stimulant properties. The plant is large-stemmed (up to 10cm in diameter); the bark is "corky gray" with white wood. The "small, yellowish-white, sweet-scented" flowers vary between 6 to 10 centimeters across; the fruit produced is a drupe, "about 1 cm in diameter when dry".

An illustration of an Agathis branch. The genus Agathis, commonly known as kauri or dammar, is a relatively small genus of 21 species of evergreen trees in the very ancient Araucariaceae family of conifers. While initially widespread during the Jurassic period they are now found only in small areas of the southern hemisphere. The trees have characteristically very large trunks and little or no branching for some way up. Young trees are normally conical in shape, only upon maturity does the crown become more rounded or irregularly shaped.

The Olive (Olea europaea) is a species of small tree in the family Oleaceae, native to the coastal areas of the eastern Mediterranean region, from Lebanon, Syria and the maritime parts of Asia Minor and northern Iran at the south end of the Caspian Sea. Its fruit, the olive, is of major agricultural importance in the Mediterranean region as the source of olive oil. The Olive tree is an evergreen tree or shrub native to the Mediterranean, Asia and parts of Africa. It is short and squat, and rarely exceeds 8–15 meters in height. The silvery green leaves are oblong in shape, measuring 4–10 cm long and 1–3 cm wide. The trunk is typically gnarled and twisted.The small white flowers, with four-cleft calyx and corolla, two stamens and bifid stigma, are borne generally on the last year's wood, in racemes springing from the axils of the leaves. The fruit is a small drupe 1–2.5 cm long, thinner-fleshed and smaller in wild plants than in orchard cultivars. Olives are harvested at the green stage or left to ripen to a rich purple colour (black olive). Canned black olives may contain chemicals that turn them black artificially.

Sumac is any one of approximately 250 species of flowering plants in the genus Rhus and related genera, in the family Anacardiaceae. The dried berries of some species are ground to produce a tangy purple spice often used in juice. Sumacs grow in subtropical and warm temperate regions throughout the world, especially in North America. Sumacs are shrubs and small trees that can reach a height of 1-10 meters. The leaves are spirally arranged; they are usually pinnately compound, though some species have trifoliate or simple leaves.

Eastern Black oak (Quercus velutina), or more commonly known as simply Black Oak is an oak in the red oak (Quercus sect. Lobatae) group of oaks. It is native to eastern North America from southern Ontario south to northern Florida and southern Maine west to northeastern Texas. It is a common tree in the Indiana Dunes and other sandy dunal ecosystems along the southern shores of Lake Michigan. It is most often found in dry well draining upland soils which can be clayey or sandy in nature in most of the rest of its range. In the northern part of its range, black oak is a relatively small tree, reaching a height of 20-25 m (65-80 ft) and a diameter of 90 cm (35 in), but it grows larger in the south and center of its range, where heights of up to 42 m (140 ft) are known. Black Oak is well known to readily hybridize with other members of the red oak (Quercus sect. Lobatae) group of oaks being one parent in at least a dozen different named hybrids. he inner bark of the black oak contains a yellow pigment called quercitron, which was sold commercially in Europe until the 1940s.

Safflower (Carthamus tinctorius L.) is a highly branched, herbaceous, thistle-like annual, usually with many long sharp spines on the leaves. Plants are 30 to 150 cm tall with globular flower heads (capitula) and commonly, brilliant yellow, orange or red flowers which bloom in July. Each branch will usually have from one to five flower heads containing 15 to 20 seeds per head. Safflower has a strong taproot which enables it to thrive in dry climates, but the plant is very susceptible to frost injury from stem elongation to maturity.

The Young Men's Christian Association ("YMCA" or "the Y") was founded on June 6, 1844 in London, England, by George Williams. The original intention of the organization was to put Christian principles into practice, as taught by Jesus Christ. The YMCA idea, which began among evangelicals, was unusual because it crossed the rigid lines that separated all the different churches and social classes in England in those days. The movement extended to the United States in December 1951. The 23rd Street Branch was torn down in 1903.

An illustration of a hand loom. he earliest looms were vertical warp-weighted looms, with the warp threads suspended from a branch or piece of wood and weighted or attached to the ground. The weft threads would be pushed into place by hand or a stick that would eventually become the shuttle. At first, it was necessary to raise and lower every warp thread one at a time, which was a time-consuming and laborious process. Basic techniques, such as the insertion of a rod, were developed to produce a shed, the space between warp threads (perhaps every other thread would be alternately raised and lowered), so that the weft thread or shuttle could pass through the entire warp at once.

The Foraminifera, ("Hole Bearers") or forams for short, are a large group of amoeboid protists with reticulating pseudopods, fine strands of cytoplasm that branch and merge to form a dynamic net. They typically produce a test, or shell, which can have either one or multiple chambers, some becoming quite elaborate in structure. These shells are made of calcium carbonate (CaCO3) or agglutinated sediment particles. About 275,000 species are recognized, both living and fossil. They are usually less than 1 mm in size, but some are much larger, and the largest recorded specimen reached 19 cm.

An illustration of two Hittite women sitting. The Hittites were an ancient Anatolian people who spoke a Hittite language of the Anatolian branch of the Indo-European language family, and established a kingdom centered at Hattusa in north-central Anatolia (on the Central Anatolian plateau) ca. the 18th century BC. The Hittite empire reached its height ca. the 14th century BC, encompassing a large part of Anatolia, north-western Syria about as far south as the mouth of the Litani River (a territory known as Amqu), and eastward into upper Mesopotamia. After ca. 1180 BC, the empire disintegrated into several independent "Neo-Hittite" city-states, some surviving until as late as the 8th century BC.

The cephalopods are the mollusk class Cephalopoda characterized by bilateral body symmetry, a prominent head, and a modification of the mollusk foot, a muscular hydrostat, into the form of arms or tentacles. Teuthology, a branch of malacology, is the study of cephalopods. The class contains two extant subclasses. In the Coleoidea, the mollusk shell has been internalized or is absent; this subclass includes the octopuses, squid, and cuttlefish. In the Nautiloidea the shell remains; this subclass includes the nautilus. About 786 distinct living species of cephalopods have been identified. Two important extinct taxa are Ammonoidea, the ammonites, and Belemnoidea, the belemnites Cephalopods are found in all the oceans of Earth, at all depths. None of them can tolerate freshwater, but a few species tolerate more or less brackish water.
