"It may appear as an anomaly to, many", he says, "that while the Indian cul- ture went over to Champa and Camboja so early it is so late in penetrating into Siam." He however gives his reasons. "It may be explained as due to Siam being part and parcel of the mighty empire of Camboja ;'J Further on in ch. VIII (p 89), "We can not strictly draw a line of demarcation between the two ancient kingdoms of Camboja and Siam. The ancient Camboja at present comprises both (i) Camboja, under the French Protectorate and (2) Siam proper". I wish Mr. Bose had emphasised a little more on this aspect of the question as it explains the early hinduisation of the people inhabiting the valley of the Menam. This was certainly the early Indian substratum on which the Thai built all their cultural superstructures. Later on the Siamese kings when they adopted Bud- dhism imported missionaries from Burma and Ceyloa but that presupposes a previous acquaintance with some sort of Indian culture which they received from the people with whom they mixed up. Ch IV> V, VI deal respectively with the dynasties of Sukhothai (?— 1349), Ayuthia(i350-i767),& Bangkok (1767—1926).
