OCCASIONAL NOTES. 171 



were all horizental, and in the Peninsula ran from West to East. 

 From the nature of the vibrations it may be sug-gested that 

 the shock itself was at a considerable distance from Singapore. 

 The exact direction in which the wave ran does not appear to 

 be quite certain, as no one seems to have attempted to settle 

 it by experimentat the time. From Malacca the vibrations are 

 reported to have come from the N N.W. and this is probable 

 as they were more violent at Deli which is N.N.W. of Malacca. 

 At Pasir Panjang they apparently travelled S.S.W. to N.N.E. 

 or from S.W. to N. E. At Tanglin they appeared to travel 

 from S.W. to N.E., but from the movements of a certain door, 

 I believe they were really from the North-West. 



In ]\Iedan, on the other hand they were felt as travelling 

 from East to West. If this is correct, the starting point of the 

 shocks must have been somewhere between South of Deli 

 and North of Malacca, and a volcano called Sarek Berapi is 

 said to have been the one from which the vibrations started. 

 In conclusion, it is, I think, worth remarking that the weather 

 for some time before the earthquake occurred was remarkably 

 hot and oppressive in Singapore, as unusually hot weather has 

 in other cases of earthquake been observed as preceding the 

 shock.

ON THE OCCURRENCE OF THE RARE 

 BAT-HAWK IN JOHOR. 



In December last, the Bird Collector of the Raffles Museum 

 shot in Johor a fine specimen of the very rare Hawk, 

 Machoerhamphus alcinus (Westerm.). 



Of the genus Machcerhamp/ms, only two species are known, 

 viz., this one and M. Andersoiti, whose habitat is Damara 

 Land in South-West Africa, and Madagascar. 



With reference to M. alcinus, Mr. E. W. Oates in his 

 •' Birds of British Burmah" says : — 



'* The slender-billed Pern is a very rare species, about which 

 " little is known. Mr. HoUGH procured one specimen at
