With the use of Global Navigation Satellite System (GNSS) technology, it is now possible to determine the position of points in 3D coordinates systems. Lagos datum is the most common Mean Sea Level used in most parts of Nigeria. In Niger Delta, for instance Warri and its environs, the most commonly used datum for height determination is the Mean Lower Low Water Datum. It then becomes necessary to determine a constant factor for conversion between the two datum when the need arises as both are often encountered during Geomatics Engineering field operations. In this paper, the constant to be applied in converting between both datum was determined. The constant was found to be 17.79m. The horizontal and vertical accuracy standard was also determined as well as the stack maps.

SummaryJohannes Rebmann, the first European to set eyes on Mount Kilimanjaro, served as a pioneer missionary in East Africa in the mid-nineteenth century, commissioned by the Anglican Church Missionary Society. Lexicography was his main occupation, but he faced several serious challenges: theological and methodological differences with his closest colleague, colonialism and slavery, and personal health problems. The author of this book has himself served in Malawi and participated in the recent English-Chichewa dictionary. Paas uses an impressive number of primary sources, letters and archival materials to paint the picture of Rebmann, his life and work.RÉSUMÉJohannes Rebmann, le premier européen à avoir contemplé le Kilimandjaro, a été un missionnaire pionnier en Afrique de l’Est au milieu du dix-neuvième siècle, envoyé par la société missionnaire de l’Église anglicane. Il s’est principalement consacré à un travail lexicographique, mais il a dû faire face à diverses difficultés sérieuses : des différences d’ordre théologique et méthodologique avec ses plus proches collègues, le colonialisme et l’esclavage, ainsi que des problèmes de santé. L’auteur de cet ouvrage a lui-même servi au Malawi et a participé à l’élaboration du récent dictionnaire Anglais-Chichewa. Paas a consulté un nombre impressionnant de sources de première main, de lettres et d’archives pour dresser le portrait de Rebmann et présenter sa vie et son oeuvre.ZusammenfassungJohannes Rebmann, der erste Europäer der jemals den Kilimandscharo erblickt hatte, diente in der Mitte des 19. Jahrhunderts als Pioniermissionar in Ostafrika; er war ausgesandt von der Missionsgesellschaft der anglikanischen Kirche. Seine Hauptbeschäftigung war die Lexikographie, aber darüber hinaus wurde er mit diversen ernstlichen Herausforderungen konfrontiert: Es gab Unstimmigkeiten zwischen ihm und seinem engsten Mitarbeiter über theologische Ansätze und die Methodik ihrer Arbeit, er befand sich in einem Umfeld von Kolonialismus und Sklaverei, und er geriet persönlich in gesundheitliche Schwierigkeiten. Der Autor dieses Buches hat selbst in Malawi Dienst getan und an dem unlängst erschienenen Wörterbuch auf Englisch-Chichewa mitgearbeitet. Paas verwendet eine bemerkenswerte Zahl an Primärquellen, Briefen und Archivmaterial, um ein Bild von Rebmann, seinem Leben und Werk zu zeichnen.

A new genus, Pseudotheraptus, is described for a Coreid bug, Ps. wayi, sp. n., Causing early nutfall of coconuts in East Africa. Two other species, Ps. devastans (Dist.) and Ps. ugandae, sp. n., are placed in this genus, with descriptions and a key for determination of the three species.The taxonomic relation of Pseudotheraptus to other genera is discussed, with particular reference to Theraptus, in which the species now described as Ps. wayi was formerly placed provisionally, and to Amblypelta, of which one species (A. cocophaga China) is the cause of identical damage to coconuts in the British Solomon Islands Protectorate.A key is given for the determination of the two species now remaining in the genus Theraptus.
