Southeast Asia a Part of Gondwanaland?

ON the basis of several different lines of reasoning, Ridd1 hypothesized that southeast Asia, from at least north Thailand and northern Vietnam down to Borneo and Java, formed part of Gondwanaland until the latter's break-up during Mesozoic. A similar belief, though without the details of supporting evidence, has been expressed recently by Tarling2. In Ridd's reconstruction (ref. 1, Fig. 2), southeast Asia, rotated clockwise about 45°, is fitted neatly between India on the west and Australia on the east.

SOME NOTES ON THE DIPLOID CHROMOSOME NUMBER OF THE GENUS ACORUS L. (ARACEAE)

The meiotic chromosome number of a specimen of the genus Acorus L. from North Thailand proved to be 12. This confirms 24 as the diploid somatic number of the genus and not 18 as is sometimes supposed.

Cancer in Chiang Mai, North Thailand. A relative frequency study.

The relative frequency of histologically diagnosed cancer at the Chiang Mai Medical School in North Thailand in 1964-67 inclusive is examined.Most of the 1877 cancers seen are in Thais (males, 927; females, 908), the remainder arising in Chinese (males, 21; females, 12), Hill People (males, 6; females, 1) and others (females, 2). The cancers in Thais are presented by site, sex and 10-year age-group together with the relative frequency (crude and corrected for age).In Thais, the outstanding finding is the extraordinarily high frequency of cancer of the hypopharyngeal-laryngeal region in both sexes (males, 18.4 per cent; females, 3.4 per cent). This may be associated with the smoking of a local variety of the cigar called "keeyo" This cigar, smoked in the usual manner, contains approximately equal quantities of home-grown, sun-dried, Thai tobacco and the chopped bark of the "koi" tree (Streblus asper). In women, who also smoke "keeyo", the frequency of hypopharyngeal-laryngeal cancer is unusually high by occidental standards. There is no sex difference in the frequency of bronchial cancer (4 per cent).In males cancer of the penis, in second rank (6.6 per cent) is much more frequent than cancer of the prostate and testis combined. Stomach and skin cancers (ICD 191) are in third place (each 5.7 per cent).In females the most frequent cancers are cervix uteri (19.8 per cent), breast (8.8 per cent) and skin (ICD 191) (6.1 per cent). Cancers of the lip and skin of the head and neck are more frequent in females than in males. Choriocarcinoma is common (1.9 per cent) and there is a large number of vulvar cancers in young women (2.6 per cent).The geography, economy and medical facilities of Chiang Mai Province are described. It is considered that, although there is likely to be considerable under-reporting of internal cancers, the high frequency of hypopharyngeallaryngeal cancer is not due to selective bias.

Hoabinhian: A Pebble-Tool Complex with Early Plant Associations in Southeast Asia

The term "Hoabinhian" has been applied to "mesolithic" assemblages from all parts of mainland Southeast Asia. Recent excavation in north Thailand has yielded the first associated carbon-14 dates and provided evidence for the early (about 7000 B. C.) domestication of plants in Southeast Asia.

Murine typhus in Thailand

Collections were made of rodent tissues, ectoparasites and human sera from widely scattered areas of north, north-east and central Thailand, in a search for murine typhus. Rickettsia mooseri was recovered from 35 1215 Rattus exulans, 1 209 R. rattus and 2 human cases of fever of unknown origin. No recoveries were made from 297 R. norvegicus, 38 Suncus murinus or 26 Bandicota indica. Antibody prevalence in human residents of trapping areas ranged from 0 to 20%. The findings suggest that murine typhus may be of more importance in Thailand than generally assumed. Further studies are under way.

The geographic distribution of histoplasmin sensitivity in Thailand.

SummaryHistoplasmin skin tests were applied to 4,211 lifetime residents of eight geographic areas in Thailand. The range of histoplasmin sensitivity was found to be 4.8 to 34.4%, depending on the test area. The prevalence of histoplasmin sensitivity was uniformly low among residents of north and northeast Thailand, whereas rates in south and central Thailand were among the highest yet reported in Asia.

Surveys on chloroquine resistant P. Falciparum in Thailand

Surveys for the prevalence of chloroquine resistant P. falciparum were carried out in north, central and south Thailand. The frequency of unsatisfactory response to 1500 mg. of chloroquine base ranged from a high of 85% to a low of 6% in different areas. In a series of hospital patients 37·5% had a poor clinical response and 25% an inadequate parasitological response.

An Interpretation of Northern Thai Peasant Economy

A venerable occupation in North Thailand is the production of miang, a delicacy consumed as a snack or dessert by local people and by those of neighboring regions ranging from Assam to Tonkin and north through Yunnan. The product is prepared from tea leaves fermented by peasants living along the upper slopes of the Northern hills, the natural habitat of the wild tea shrub. The finished product is transported from there to wholesalers located in most sizable towns and villages of the lowlands. Each market place in lowland villages includes the stall of at least one miang vendor, who is supplied with inventory on a credit basis by the wholesaler and who retails the commodity by the bundle or by the chew, each unit, ordinarily laced with a dash of salt, garlic, sugar-water, or shredded coconut, selling for one baht (approximately U. S. $ .05) or less.

China, Thailand and the Spirit of Bandung (Part I)

Political relations between the Kingdom of Thailand and the People's Republic of China are conditioned by important historical, geographical and social facts. While Thailand and China are situated in close proximity to each other on the north and south-west respectively, they do not have a common border; a narrow strip of both Burma and Laos joins to form an intervening corridor. This border region shared by the four countries is an area of rugged mountains and primitive communications. Neither railroad nor all-weather highway connects China with Thailand. The most effective form of land communication between Chiengrai in north Thailand and Che-li in China's southern province is by horseback. The possibility of the movement of heavy traffic over difficult terrain cannot be denied since the experience of the siege of Dien Bien Phu. There are roads of some sort from Yunnan through Burma to Chiengrai, and also (and probably more importantly) from Vietnam through Laos to Nongkhai and Nakhon Phanom.

On the distribution of ABO blood groups in the North Thailand population

2048 subjects in North Thailand were examined for AB0 blood groups. A control group representative of the population of the provinces of Chiengmai and Lampun was formed of 382 examinees and 3403 blood donors.

Die Verbreitung erblicher Farbsehst�rungen in der Bev�lkerung Nordthailands

The incidence of color vision defects was determined in two populations of North Thailand. In the Thai population, wet rice growers since earliest times, an incidence of 5.17% in males was found (Ishihara plates). In the Miao hill tribe, people relying on hunting, for their protein supply to a large extent, the incidence was 2.24% in males. The difference is significant and, together with the different ecologic situation, in favor of Post's selection relaxation hypothesis.

A Comparative Study of the Yao Tone System

In my article 'On the tone system of the Miao-Yao languages'l I dealt chiefly with Miao data. With the additional data on Yao made available in recent publications I can now reconstruct the tonal system of Proto-Yao in greater detail and with more certainty. The terms Miao and Yao refer both to peoples and to languages. The Yao people speak Mien, a Yao language; Punu, a Miao language; and Laka, a language whose relations are still uncertain.2 Yao, in contrast to Miao, has a complicated system of finals: vowels may occur in final position, or they may be followed by -y, -w, -p, -m, -t, -n, -k (in some dialects -?), or -9. Miao, on the other hand, has a complicated system of initials, with both simple consonants and consonant clusters, which Yao for the most part lacks. Some differences in vocabulary also characterize the two. The Yao dialects whose tone systems I shall discuss here are the following. 1. HKP: Herbert Purnell Jr. studied the dialect of Hweikang Pa (Yanglae), in the District of Maechan, Chiengrai Province, North Thailand, from April 1963 to May 1964. His Phonology of a Yao dialect contains perhaps three hundred forms. The tones of HKP are (1) mid-high (unmarked): normally level, an occasional alternant has a very slight fall: mhyen 'face';4 (2) mid: a falling contour beginning around the middle of the vocal range and ending near the bottom: my6n 'people'; (3) high: a slight rise followed by a fall to median pitch when the syllable does not end in a stop: cui 'dog'; level when the syllable ends in a stop: sip 'red'; (4) low-mid: slightly rising followed by a fall to the bottom of the range, with pharyngealization throughout: tui 'pig'; (5) mid-low: a rising contour beginning slightly below median pitch and ending somewhat above it: pw6y 'to sleep'; (6) low: level, with glottalization ('creakiness') throughout, occasionally with a very slight fall: nin 'to eat', tUb 'bean'. 2. PKT: In 1959 and 1960, G. B. Downer collected data from the villages of P'u K'amteng and Chungliang, about four and seven hours respectively from Muongluang Namtha on the Muongsai trail in northwestern Laos. His 'Phonology of the word in Highland Yao'6 contains more than two hundred examples and a short text. The tones of PKT are (1) mid-high level: hman 'face'; (2) midhigh, falling to low: mian 'people'; (3) high rising-falling: only when the syllable

A gabbro—granodiorite association in Singapore Island

The syntectonic tin-bearing granite batholith system of the Thai-Malayan orogeny is associated in several places from north Thailand to Singapore with satellitic bodies of basic composition. In Singapore Island such a body of gabbroic composition is marginally situated within the batholith, and exposures indicate that it is pre-orogenic. The orogenic granodiorite has intruded the gabbro in the form of irregular dykes, producing at the immediate contact a variety of hornblende-rich rocks by thermal metamorphism and hybridization. The dykes are crowded with gabbro xenoliths in every stage of assimilation. A similar petrogenetic sequence and enrichment in hornblende is to be found in gabbro-granodiorite associations in most orogenic regions of the world.
