342 ON THE SO-CALLED TIGER’S MILK. 
Through the mass runs a fine whiter network visible with the 
naked eye, which consists of chains of cells with more gra- 
nular opaque contents. The red rind consists of a very fine 
granular layer, in which I cannot perceive any cellstructure. 
It is very certain from this that it is no animal structure, 
and that it is very improbable that the climbing plant suppos- 
ed to be produced by it has anything to do with it, but that 
it is of the nature of a fungus. The Malays say that it is 
found under ground, but the specimen obtained at Bukit 
Mandal, was growing upona rotten tree, and to it was at- 
tached a fungus of the genus Polyporus, species of which are 
so abundant on rotten timber in the jungles. 
Some similar bodies are known from several parts of the 
world, and have been described, but at present their origin is 
very obscure, and I[ think it will be well to compare the known 
kinds with our Tiger’s Milk, and see wherein it differs. 
RUMPHIUS described and figured a fungus which he called 
Tuber Regium, in the Herbarium Amboinense (Vol. VI 
Plate LVII 4, p. 120). The picture represents a) bodyilimes 
a smooth block of earth on which a number of fungi evidently 
belonging to the genus Lentinus are growing. IRUMPHIUS 
gives along account of the “ Royal Tuber.” He says it is very 
common in April and October when the rainy season is on, 
and that then it is quite soft and not durable, and although his 
picture represents it as quite smooth, he says that when sud- 
denly dried, it becomes cracked and fissured: when he planted 
it in his garden and watered it with warm water it produced 
the fungi, but perished next year. The Lentinus is eatable, 
but hardly worth eating. The tuber he recommends for diar- 
rhea grated and mixed with rice and also mixed with oil as an 
ointment for sore mouths. Eaten raw he says it is insipid and 
earthy. He gives the following names for it, none of which 
occur in FILET’S Javanese Dictionary :—Malay, Uéz Raza, and 
Culat Batu, Amboinese Mathata Utta batuand Uttah putth.. 
In Hitoe it is called Zadalale (without heart), and in Ulias- 
sens, Urupickal. In Java Djanjor bongkang (dung of the 
Python); in Ternate Cadamaisse (earth-tuber). It was com- _ 
mon in Oma, Leytimor, Gorama and Ternate under grass on
