UjS'TIL Mr. E. B. ISTewton described certain fossils from Singapore 

 found by the writer and Dr. Hanitscb of the Raffles Library and 

 Mnseum/ very little was known of the geology of this island, which 

 is the nearest of the British JMalayan possessions to those parts of the 

 lyTetherlands Indies that have been so ably described by Verbeek, 

 Pennema, Molengraaf, Wing Easton, Martin, and others. This 

 proximity to the islands of the archipelago renders the study of the 

 geology of Singapore doubly interesting, since here may be expected 

 data that will eventually assist materially in connecting the geology 

 of the Malay Peninsula with that of the Malay Archipelago, and more 

 particularly with that of Borneo. The object of the present paper is 

 to show that the sedimentary beds of Singapore may be referred to 

 one of the series of rocks which enter into the structure of the 

 Federated Malay States. 



At the time of the publication of the writer's "Report of Progress " ^ 

 a few opportunities of collecting notes in Singapore had been obtained, 

 and a similarity between the sedimentary rocks and the Tembeling 

 Series of Pahang, the main outcrop of which is on the same line of 

 strike as the Singapore rocks, had been noticed.^ A glance at the 

 accompanying sketch-map (Plate XI) will show, however, that between 

 Pahang and Singapore there intervenes the large native State of Johore, 

 the interior of which is unbroken ground to geologists ; and it was felt
