ON THE MfiDICAL TOPOGRAPHY OF SINGAPORE, 
453 
8 years ago, now feel it only a little less than the inhabitants of the 
town on the sea beach. This same hot wind has been felt by Mr. Thom¬ 
son the government Surveyor in Pinangand Province Wellesley. One 
fact more may however be mentioned concerning it, that it does not 
exist where the jungle reaches the sea beach, and that when a cleared 
country becomes again covered with trees, this hot wind disappears, 
as the land breeze extends itself seaward.* 
The following meteorological tables, except where otherwise no¬ 
ticed, are formed from observations taken at the Singapore Obser¬ 
vatory. 1 am only sorry that I had not an opportunity of obtaining 
many necessary explanations from the talented observer, from his 
limited sojourn in this place ; but it is to be hoped that these tables 
will be published in full at some future period not far distant, which 
reconciles me to giving the following necessary, but meagre extracts.

p. 137-8. 
[Our able contributor’s explanation appears to be substantially the same 
as ours. The phenomenon resolves itself in t the difference in tempera¬ 
ture between the land and sea nocturnal atmospheres. The latter, through 
the prevalence of the southerly wind, encroaches on the limits of the former. 
Why the southerly wind should continue to blow over the land ; t night is a 
further question, which our contributor leaves unexplained as we did. Uur-
