History and Catalogue of Manuscript Charts on Vellum of the Dutch East India Company (VOC), 1602-1799
Authors: Günter Schilder and Hans Kok
The Vereenigde Oostindische Compagnie (Dutch East India Company) was for a period of 200 years responsible for the navigation material for the journey between the Netherlands and the Far East and the inter-Asian trade. In this book with the help of recovered archive materials a never published before overview is given of chart material that was used on a VOC-ship.
All navigation charts of the VOC in the 17th and 18th century, drawn on vellum (of which many were traced in foreign collections), are described and analysed in an illustrated cartobibliography. In a supplement extracts of the 'groot-journalen' of the 'Kamer Amsterdam' are published. These give an unique view of the total expenses of the VOC on navigation. The extensive introduction gives more information on the history of the VOC, the chart makers, the routes, the navigation and the instruments. Inlcudes CD-rom with appendices.

History & Catalogue of Dutch Charts Printed on Vellum 1580-1725
Authors: Günter Schilder and Hans Kok
Maps printed by commercial Amsterdam charts publishers between the sixteenth and the eighteenth century are spread all around the world. This illustrated cartobibligraphy describes and analyses about 150 charts, mostly found in international institutions. With over 800 full colour illustrations, many full page, it offers an overview of maps from Europe to the Indian and the Atlantic Ocean, the latter commonly called 'West-Indische Paskaerten'.
The first part of the book contains six chapters that investigate the development of Amsterdam as a recognized centre for map production and distribution in Europe. It also discusses navigation techniques used in the sixteenth and seventeenth centuries and the developing world image.

The Dutch East India Company (VOC) manuscript charts on vellum are discussed in Sailing for the East (ESHC 10, 2010).


Egg masses of Meloidogyne fallax from tomato and potato growing in soil from a nematode suppressive and a nonsuppressive field sustained bacterial population densities two to three orders of magnitude higher than those of the rhizosphere soil. BIOLOG metabolic profiling identified 16 bacterial species from egg masses. Results further indicated 20 species not listed in the BIOLOG database. 122 isolates of bacteria and 19 isolates of fungi from M. fallax or M. hapla were tested for in vitro antagonism against the nematode egg parasitic fungus Verticillium chlamydosporium: 23% of the bacteria and 74% of the fungi showed antagonistic activity. Pseudomonads showed an overall stronger antagonistic activity than the other bacteria. Our conclusions are that Meloidogyne egg masses are a densely populated microbial niche and that their microflora may well be an important factor in determining the success of nematode antagonists. However, we could not find a relationship between the egg mass microflora and differences in soil suppressiveness between the sample sites.
