| De jonge Oldenburger geoloog Johann Karl Ludwig Martin, die bijzonder belang stelde in de zwerfsteenen, die gedurende het plistoceen met de gletschers uit Fenno-Skandia naar Noord-Duitschland en Nederland waren getransporteerd, werd door de verzameling van Staring van de geologie van Nederland naar Leiden gelokt, waar zij onder de directie van den zoöloog H. Schlegel in het Museum van Natuurlijke Historie op de Papengracht was ondergebracht. Nu wilde het toeval, dat in 1876 de nieuwe wet op het hooger onderwijs in werking was getreden, hetgeen de instelling van een professoraat in de geologie aan elk der drie Rijksuniversiteiten met zich bracht. |

| In the first part of this paper the species of a few of the larger genera among Sumatran Carabidae have been tabulated, either because no Keys exist already, or because the old Keys have become obsolete. The four genera included here are Colpodes, Orthogonius, Catascopus, and Dolichoctis, but for various reasons I have not dealt with Clivina, Tachys, Chlaenius, and Perigona. Most of the species of Clivina are included in the Key to the Indian species in my first volume on the Carabidae in the "Fauna of British India" Series, 1929 (p. 353), and nearly all those under Tachys appear in the tables of my "Revision of the Oriental Species" (Ann. Mus. Civ. Gen. LI, 1925, pp. 327—502); the "Tableau Synoptique" in Chaudoir's "Monographic des Chléniens" (Ann. Mus.... |

| For the compilation of the map of fossil localities I have followed the example of Dr. A. Tobler (bibl. 194), arranging the localities according to age. The localities from which more than one formation has been recorded, are numbered for the oldest formation found. In the list these numbers are repeated in brackets under the heading of the other younger formations that have also been found. Thus brackets around a number are an indication that older sediments are known from the same locality. In those fossil localities are included that occur on Dutch territory and from which a collection of the fossils has been described. Vague indications in preliminary reports have not been taken into account. |

| In dem Fossilverzeichnis sind die Arten in der Regel unter dem Namen aufgeführt den sie in der neuesten bei der Art zitierten Arbeit tragen ¹). Wenn eine Art in früheren Arbeiten über Niederländisch Indien anders benannt worden ist, so findet man die Nummern dieser älteren Arbeiten doch hinter dem neueren Artnamen. Der ältere, hinfällige Name ist in solchen Fallen in einer Bemerkung zu finden, ausserdem aber ist er auch in dem Artenverzeichnis aufgenommen, aber dort nur von einem Hinweis nach dem neueren Namen versehen, wo man also die zugehörige Literatur findet. Wenn von einer früher beschriebenen Art einige wenige Exemplare nach neuerer Bearbeitung zu einer anderen, schon vom selben Fundort bekannten Art gebracht worden sind, so sind diese wenigen... |

| The Netherlands is to be congratulated in having available within its borders such an outstandingly important collection of historical botanical material as that preserved in the Rijks Herbarium at Leiden. To a greater and greater degree the importance of this great assemblage of botanical specimens becomes manifest as critical work is done on it and on the corresponding collections in other botanical centers, and as various natural groups are treated monographically. In many groups of plants, particularly those represented in the Netherlands East Indies, the Rijks Herbarium is the court of last resort in determining the exact status of many hundreds of described species, because in this collection are deposited the actual types of the very numerous... |

| The grasses constitute a very well defined natural group of plants, but the division of this family into tribes and subtribes is a difficult problem. We know that ROBERT BROWN divided the family into the Panicaceae and the Poaceae. BENTHAM already indicated that in the former the tendency to imperfection lies in the lower flowers of the spikelets, whereas in the Poaceae the tendency is in the opposite direction, but he observes at the same time that this principle is too indefinite to serve as a practical character to recognize both groups. In combination with other characters, especially those taken from the fruits (the caryopsis, enclosed by the scales), these two groups become however more stabile. KUNTH gave us no less than 13 tribes, many of them... |

| In the bay of Emmahaven near Padang (W. Sumatra) is a small coral reef. On the North side of this reef a small, sandy island occurs called Pasir Ketjil. It has lately been surrounded by brick walls, besides which a stone pier has been built in a S.W. direction (cf. fig. 1, a map of 1899 and fig. 2 and 3, the present condition). Since the building of that pier, coral sand has accumulated against it on the S-side. This reef lacks shingle ramparts. From this situation of the sandy island with regard to the reef, and from the placing of the younger coral sand accumulations (A in fig. 3), it may be concluded that the maximal wind-effect is strongest from the direction of the open sea, about S.W. Data about the wind frequency kindly supplied by the director of... |

| The number of fossils that have been described from the Netherlands Territory in America is not very large. The descriptions are, however, scattered over a rather large number of publications, many of which will be found only incidentally by a reader who occupies himself intensely with the geological literature on the Antilles. It has therefore seemed to me to be a useful work to gather the data on these fossils as completely as possible, and the making of this catalogue has been especially agreeable to me, as a very large part of the fossils under discussion have been collected by Prof. Martin, in whose honour this book is edited. Some remarks may precede the catalogue. |

| Den Wert von Bibliotheken, Archiven, Museen, Herbarien zu begreifen, ist nicht jedermann gegeben. Es gehört dazu eine gewisse belebende Phantasie, ein Sinn für Mannigfaltigkeit von Erscheinungen und eine Gabe, aus dem Vergleich verschiedener Dinge Einsicht zu schöpfen. Nicht alle Menschen haben diese drei, auch manche Botaniker nicht. Legt man solchen ein Herbarium vor, so wissen sie nichts damit anzufangen, sie fühlen sich eher abgestossen von den Pflanzenmumien, die sie erblicken. Haben sie das nötige Temperament, so erklären sie wohl frisch und frei, das ganze trockene Zeug sei nutzloser Plunder. Derartige Radikalen wird niemand umstimmen können, und es ist überflüssig, den Versuch dazu zu machen. Aber je nach Zeit und Ort wird ihre naive Kritik... |

| The following enumeration contains the fossil plants, found not only in the Dutch territory, but also in the adjacent countries, the Malay Peninsula, British Borneo, Portuguese Timor and the Eastern part of New Guinea. The Philippine islands have not been considered. The classification used, is from Engler and Prantl, as given in the „Die Natürlichen Pflanzenfamilien” and the „Syllabus” of the former author. The species of flowering plants are placed in alphabetical order in the families; the species in the other classes have been arranged in larger groups. Only in some cases, still living plants were mentioned in the literature under obsolete names; in this case the fossils have been given their present names. Of the recent plants the present distribution... |

| De stichting van ’s Rijks Herbarium kwam tot stand bij Koninklijk Besluit van 31 Maart 1829 (zie Bijlage 1). De basis voor ’s Rijks collecties werd gevormd door de verzamelingen van BLUME, KUHL en VAN HASSELT, en ZIPPELIUS, welke door BLUME uit Nederlandsch-Indië waren meegebracht, terwijl BLUME zelf tot Directeur van het Instituut werd benoemd. De rijke, grondleggende collecties voor de studie van de flora van Nederlandsch-Indië — het Rijks Herbarium — zou in een gebouw te Brussel worden ondergebracht en bij schrijven der Regeering der Stad Brussel No. 670 van 23 Febr. 1830 werd aan BLUME meegedeeld, dat zoodra mogelijk in het Koninklijk Athenaeum de noodige vertrekken tot provisioneele opberging van het Rijks Herbarium ter beschikking zouden worden... |

| The oldest sediments on Curaçao are jasper¹), diabasetuff, siliceous slates²), radiolarian chert³), quartzporphyrite-crystal tuffs, porphyritecrystal tuffs, lithic porphyrite tuffs, tuffites, tuffite breccias, aphanitic crystal tuffs, tuffite-shales, graywacke-shales and graywackes4). This group of rocks — the Knip-series — is named after the plantation Knip. The stratigraphic sequence of the Knip-series is difficult to ascertain. They are intensively folded¹). I believe it would be safe to assert, that the oldest sediments of this series are jasper and diabase tuffs. The North limb of the anticlinorium in North-West Curaçao is very intensively folded, the South limb, however, in lesser degree, so that on the plantations Sint Jan, Groot St. Martha, St.... |

| Our knowledge of the stratigraphy of the young-paleozoic and particularly of the post-paleozoic rocks of the Netherlands East Indies is fairly extensive. Very little is known about the older paleozoic. Older paleozoic sediments are mentioned on various occasions, but the determination of the age of the rocks is mostly based on an assumption, that is made more ore less probable by the stratigraphic relation to younger fossil-bearing rocks, and not by the actual fossils, which are typical for that formation. The metamorphic rocks, which are exposed over large areas, were considered by early investigators as to belong to a very early epoch of geologic history: mostly pre-cambrian. A few fossils proved the presence of younger metamorphic rocks since. Part of... |

| Before the visit of Prof. Rutten and his students in 1930, only once geological investigations were made on Bonaire. These took place in 1885, when Prof. Martin paid a short visit to the island. Though the stay of Prof. Martin on Bonaire lasted only four days, he nevertheless succeeded in composing a rough scheme of the geology of the island. I am very glad and I count it as an honour to have the opportunity of prosecuting the work of Prof. Martin. A visitor to Bonaire must, even before reaching the road of Kralendijk, observe the great topographical difference between the northern and the southern part of the island. One does not say too much when one asserts that Bonaire consists of two totally different parts. Of these, the northern part is higher and... |

| Au printemps 1929, j'entrepris de dresser la carte d'une partie des Alpes Bergamasques, partie limitée à l'Est par celle que Jong a traitée. La frontière méridionale est formée en partie par la Valsassina jusqu'à Cortenova, en partie par la faille du Val Torta-Baiedo (Baiedo se trouve à 1½ km au SSW d'Introbio). De Cortenova à Premana le Val Rossiga et le Val Marcia séparent mon terrain de celui de mon collègue Buning. Vers le Nord il s'étend jusqu'au Val Varrone et jusqu'à la crête qui va vers la Bocchetta di Trona, en passant par le Pzo. Cavallo et le Pzo. Melasc. Diverses circonstances ne m'ont permis de terminer mes travaux de mise en carte définitive qu'au cours de l'été 1931. |
