Teyler’s Museum

Teyler s Museum at Haarlem, The Netherlands, retains one of the most complete collections of scientific instruments amassed by an institution for the purpose of teaching and research. An earlier volume, published in 1973, elucidates the collection acquired by Martinus van Marum between 1784 and 1837. The current volume, compiled by the same author, deals with the period c. 1840 to 1915.88 A somewhat smaller proportion of the 454 entries deal with chemical apparatus compared with the earlier period, but what is to be found is not without interest, including an extensive set of equipment for testing the quality of town gas.
