Description of the Samples. 
No. i— Gutta Taban Putih from Palaquium puslulatum ? 
The specimen was a conical mass which possessed a curious 
colour externally, yarymg from brown to bluish black, but when 
freshly cut it was almost white within. It was hard, vert tenacious 
and contained very little foreign matter. On immersion in hot 
water ,t softened becoming plastic but not sticky, and could be 
.readily moulded, after whirl, treatment it returned to its ordinal 
condition on standing - . * 1

No. 2.— Gutta Simpor from Palaquium Maingayi. 
This was a rounded cake, light brown externally, but whitish 
withm which had a distinct cinnamon odour, and contained a small 
amount of loreign vegetable matter. It was hard in the mass but 
the inner portion were ensile friable, whereas the outer layers were 
tougher and somewhat laminated; the greater part of the sample 
was easily reduced to coarse powder in a mortar. It became plastic 
but not sticky when immersed in hot water and the water acquired 
a slight yellow colour. After this treatment it hardened somewhat 
on standing- but exhibited little tenacity, readily breaking when 
bent. ' 
No. 3* Anita f aban C haia from Palaquium polyauf hum 
The specimen was a small rounded mass which was brown 
externally but much lighter within, and contained a small quantity 
of vegetable matter. It was hard in the m ass and exhibited con- 
siderable tenacity ; small pieces were slightly elastic and softened 
a little when held in the hand. When placed in hot water it 
beha\ ed exactly like the preceding specimen, hut exhibited much 
greater tenacity after cooling. 
No. 4.— Gutta Minjato from /My /a sp.? from the Langkawi 
Islands. 
The sample was a rectangular cake, dark brown externally but 
light brown within, which exhibited a laminated appearance when 
cut and contained a slight amount of vegetable matter. It was 
hard in the mass but fragments were easily friable, and it could be 
reduced to coarse powder in a mortar. When treated with hot water 
it formed a \erv solt sticky mass and communicated a slight yellow 
colour to; the water. After this treatment it remained flexible for 
some time, but finally became,, hard and brittle, breaking readily 
with a short fracture. 
No. Gutta Susu from Dycra sp. from the Langkawi Islands. 
This was a flat rounded cake, dirty white externally but quite 
white within and almost entirely free from extraneous yegetable 
matter. It is probably identical with commercial Pontianac,* which 
it closely resembles in appearance. I he sample was fairly hard in 
th<- mass but small pieces could be moulded in the lingers, becom- 
ing slightly sticky. O11 immersion in hot water it softened, become
