A SCIENTIFIC EXPEDITION TO TEMENGOH. g 
sweet potatoes and a kind of travelling ration in the form of a 
cylinder of pounded tapioca made in a bamboo and looking like 
a pale colored German sausage. I tasted it and found it very 
uninteresting stuff, tasteless and woody. They are monoga- 
mous and seem prolific as the old man had eight children. 
Amat and I made excursions every day into the woods as 
far as possible and collected vigorously. ‘The leeches were 
very troublesome, and extremely abundant, eventually several 
of the bites on my legs got poisoned and I was only able to 
walk with difficulty and much pain. There was much diar- 
-rhoea and fever also among the expedition. The latter was 
perhaps due to mica in the water which boiling did not get 
rid of. It would have been well to have filtered it also if .pos- 
sible. The whole of this region appears to be somewhat un- 
healthy. These ailments interfered considerably with collect- 
ing but we managed to get as good a series of the plants of the 
region as could have been expected. All the elephants of the 
country being required for the travels of Messrs. Birch and 
Berkeley we were unable to push as far as had been intended, 
there being no other means of transport. However we suc- 
ceeded in obtaining the services of two coolies on one occasion, 
and with the help of some of the Dyaks, I, my boy, and Amat 
pushed up a day’s march along the river but about midday it 
began to pour furiously with rain and having come to an old 
camping ground on the river bank, and the men being quite 
tired and all drenched, we stopped there and pitched camp 
in a furious down-pour. We had one or two water-proof 
cloths to make the hut with, but enlarged it by the use of the 
leafy stems of a ginger (Hornstedtia), the only thing we could find 
at all suitable, and after some trouble got the roof water proof. 
There being no rattans here we used the bast of the Dedaup 
(Bauhinia integrifolia) for tying. We stopped here for six 
days, the Dyaks and coolies returning the second day, 
leaving Amat, my boy and myself alone.. We collected as 
hard as we were able, pushing as far from camp as we could, 
-but both of us were really too ill to do as much as we might 
‘have done. The best collecting was, as usual in these forests,
