Dear Dr. Qui siaabins. 
Thank you for your letter of September 13th. 
As regards the Derr is specimens, w© are prepared to 
take the risk of loss in transit, will you please return 
thee as soon as you can. I suggest that they he insured 
for a sue equivalent to 50 cts. per sheet and am willing 
to nay the cost of such insurance. 
le have duly received the two parcels containing 120 
duplicates, as advised in your letter, and than: for 
this continuation of exchange. 
As regards near. monthly temperatures for Sin -spore, I 
can only supply the data for 1931-1938; and unfortunately 
there was a change in tie position of the observatory during 
the period, namely at the end of lay 1934. The observatory 
was removed from a small hill (under 100 n. high) west of 
the term to a level place near* the sea (by the airport) east 
of the town. I think It likely that there is a small mean 
difference between temperatures at these two localities, but 
it would not be core than 1 degree Fahrenheit. The four 
years 1935-1938 will give you a fair average, as the changes 
of mean temperature are always very slight. All local re¬ 
cords are published in degrees Fahrenheit. 
Yours sincerely.
