CALABAR is a district of somewhat indefinite boundaries, situated on the West Coast of Africa, in the Bight of Biafra, between 4° 20' and 6° N. lat., and between 6° 30' and 9° E. long. The name corresponds to no geographical or political unity, but is convenient as provisionally comprehending a stretch of country of considerable commercial importance. The coast line is frequently regarded as extending from the Nun mouth of the Niger, to the neighbourhood of the Cameroon Mountains, and thus includes the estuaries of the Brass River or Tuwon-Toro, the San Nicholas or Kola Toro, the New Calabar, and the Bonny, which are all deltaic branches of the Niger, as well as the San Pedro or Kan Toro, and the important embouchure of the united streams of the Cross River, the Old Calabar, and the Great Qua River. The interior of the country is still unexplored, and the inland boundary is left completely vague. The soil of the whole country, for 150 miles or further from the sea, is purely‘alluvial; and the surface is literally covered with bush except in the very limited areas under cultivation. Further inland, especially in the direction of the Cameroon Mountains, the elevation increases, the soil becomes more varied and decidedly rocky, and the forest grows clearer of underwood. This higher region is rich in natural productions, furnishing—besides the palm-oil which forms the main article of foreign trade on the coast—ebony, bamboos, sugar, pepper, yams, Indian corn, plantains, and a variety of woods....
Leaving the western portion which belongs to the delta of the Niger for treatment in the article on that river, we will confine our attention here to the district watered by the Old Calabar, the Cross River, and the Qua, which more particularly deserves the name of Calabar. The common estuary of these three rivers enters the ocean about 5° N. lat. and 8° 20' E. long. It is about 10 or 12 miles wide at its mouth, and maintains nearly the same width for about thirty miles above the bar. At the junction with the Cross River the Old Calabar forms quite a labyrinth of channels and islands, and it is also united with the Qua by a number of creeks.
The exact position of the sources of these rivers has never been ascertained, but, according to native report, that of the Old Calabar is situated in the neighbourhood of Iko, which is not very far beyond Uyanga, the furthest point inland reached by Captain Hopkins and the Rev. Samuel Edgerley in their journey of exploration in 1872. The truth of this report is rendered almost certain by the diminished size of the stream in the vicinity of Uyanga; and it is thus probable that the mountains in which both it and its sister streams take their rise are the Rimsby range, forming a western extension of the Cameroons. The Qua River is comparatively small, and navigation is impeded, at no great distance up, by sand-banks and fallen trees. Further inland its course is also broken by rapids and several cataracts.
The country watered by these rivers is occupied by a great number of separate tribes, such as the Efik, the Ekoi, the Ibami, the Oköyöng, and the Aqua, who are politically independent of each other and speak separate languages. Of these the most important are the Efik, or people of Calabar in the strictest sense of that word, which was originally applied by the Portuguese discoverers to the tribes on the coast at the time of their arrival, when as yet the present inhabitants were unknown in the district. It was not till the early part of the 18th century that the Efik, owing to civil war with their kindred the Ibibio, migrated from the neighbourhood of the Niger to the shores of the Old Calabar, and established themselves at Ikoritungko or Creek Town. In order to get a better share in the European trade at the mouth of the river a body of colonists from this city migrated further down and built Obutöng or Old Town, and shortly afterwards a rival colony established itself at Aqua Akpa or Duke Town..
For a time it seemed as if Creek Town would disappear before its younger competitors, but it was again raised to power by King Eyo Eyo, who defied the interference of his rivals. The only political bond of union between the various towns is the Egbo, a kind of secret society into which admittance is obtained on the payment of a certain fee to each of the existing members. The power of this association is almost unlimited, and is used principally for the benefit of its members. Formerly it was one of the greatest curses of the country, from the barbarous customs mingled with its rites; but it is, under European direction, being turned into a means of promulgating a more civilized code of laws through the various towns, and it forms a kind of constitutional defence against the despotism of individual kings. However unsatisfactory the condition of the country still is, there is no doubt European influence of a beneficial kind is gradually making itself felt. The universal belief in the most terrible kinds of witchcraft is slowly being shaken; the use of the esere or Calabar bean as an ordeal, and for purposes of religious purgation, is becoming much less frequent; the murder of twin children is no longer a national custom; and the massacre of his slaves on the death of a king has been abolished. The present king of Creek Town is at least nominally a Christian: and, according to Consul Livingstone, “hundreds of decently-dressed natives of both sexes regularly attend divine service” at the mission stations. These number five or six, and are supported by the United Presbyterian Church of Scotland, which began its labours here in 1846.
The predominant language, not only among the people of Calabar proper, but also of the various tribes on both sides of the Cross River, is Efik, which bids fair to be the common commercial speech of the whole district. It is really a modified Ibibio, and presents traces of what is known as alliterative concord, though this is by no means a universal characteristic. It has been reduced to writing by the missionaries, who have employed the ordinary English alphabet. Considerable progress has been made in the formation of an initiatory literature; no fewer than 65 volumes having proceeded from the mission press. Most important of these are the Efik translation of the New Testament by Ξ. Goldie (1862), the translation of the Old Testament by Dr A. Robb (1868), and a Dictionary of the Efik by H. Goldie, published in 1862. Captain James Broom Walker of Duke Town, who has explored various parts of the country, presented several charts to the Royal Geographical Society, which are reproduced in the United Presbyterian Missionary Record for 1872 and 1875.

CALABAR BEAN, the seed of a leguminous plant, Physostigma venenosum, a native of tropical Africa. The plant has a climbing habit like the scarlet runner, and attains a height of about 50 feet, with a stem an inch or two in thickness. The seed pods, which contain two or three seeds or beans, are 6 or 7 inches in length; and the beans are about the size of an ordinary horse bean but much thicker, with a deep chocolate brown colour. They constitute the E-ser-e or ordeal beans of the negroes of Old Calabar, being administered to persons accused of witchcraft or other crimes. In cases where the poisonous material did its deadly work it was held at once to indicate and rightly to punish guilt; but when it was rejected by the stomach of the accused, innocence was held to be satisfactorily established. A form of duelling with the seeds is also known among the natives, in which the two opponents divide a bean, each eating one-half; that quantity has been known to kill both adversaries. Although thus highly poisonous, the bean has nothing in external aspect, taste, or smell to distinguish it from any harmless leguminous seed, and very disastrous effects have resulted from its being incautiously left in the way of children. The beans were first introduced into England in the year 1840; but the plant was not accurately described till 1861, and its physiological effects were investigated in 1863 by Dr Thomas R. Fraser. In that year an alkaloid was isolated from the seeds to which the name physostigmine was applied; and under the name eserine another alkaloid was prepared from them; but it is not yet quite certain that the two substances are essentially different. Dr Fraser’s investigations, which were conducted with an alcoholic extract of the seeds, showed that the active ...principles exerted a remarkable influence in contracting the pupil of the eye, and in counteracting the influence of atropine. The antagonism of physostigmine and atropine and its relations to many other alkaloids have subsequently been the subject of very numerous investigations. A committee of the British Medical Association under Professor Hughes Bennett found that the antagonism between sulphate of atropine and extract of Calabar bean exists only within narrow limits, so that for practical purposes atropine is useless as an antidote to Calabar bean. The investigation of the same committee into the relations of hydrate of chloral and Calabar bean, however, proves that they are mutually antagonistic, but as the toxic influence of the Calabar bean is very rapid, it is necessary to administer the chloral as soon as possible after the Calabar bean is taken. Calabar bean in the form of powder and extract is used in medical practice. It has been chiefly employed by ophthalmists to produce contraction of the pupil, but it is also used in tetanus, neuralgia, and rheumatic diseases.
