PREFATORY NOTE 
T HE Expedition, of which the results will be embodied in 
Fasciculi Malayenses, originated in the fact that one of us 
(N. A.) had accompanied the ‘ Skeat ’ expedition, as a volunteer, 
during the first six months of its tour through the Eastern Siamese 
Malay States. It seemed that many problems, both anthropological 
and zoological, might, with advantage, be further studied in this 
district, and it was suggested by Sir William Tu that a series of 
measurements of the people would be valuable, wtiuc Professor E. B. 
Poulton considered that much light might be thrown on the subjects 
which he has made his life-work, by more detailed investigation of 
the insect fauna. The expedition was, in the first instance, rendered 
feasible by a grant of one hundred pounds, made by the University 
of Edinburgh from the Earl of Moray Fund. A grant of equal 
amount was also made, later in the year, by the Royal Society, from 
the Government Fund at their disposal. The specific purpose for 
which it was voted having been found impossible, this grant was 
afterwards transferred to our general work, largely through the kind 
offices of Professor Herdman, to whom we are indebted for 
introducing us to one another. We must also acknowledge the 
generosity of Mr. Alfred Holt, through whose directions Messrs. 
W. Mansfield & Co. acted as our agents in Singapore and Penang, 
and brought our very bulky collections home to Europe gratis. Our 
thanks are due to the British and Siamese officials with whom we 
came in contact ; more especially to His Excellency the High 
Commissioner of the Ligor Circle and to the British Resident ot 
Perak. Professors Herdman, Poulton, and Sir William Turner 
have extended the hospitality of their laboratories to us, and have 
aided us in ways too numerous for separate mention. Finally, we 
must express our acknowledgments to the gentlemen who have 
undertaken the systematic description of our collections, and to the 
generous assistance without which this report could not have been 
produced.
