159 7th. I It is felt it is better to risk anaphylactic shock than take chances with the bite. Dark & I walked over to the Oriental Hotel for dinner. We got to watching the gecos around the lights. Incidentally, at the Princess Hotel, I have seen them crawling on the fluorescent tubes when the tubes were illuminated. I watched one stalk a small insect, perhaps 4 mm. long. The lizard crawled slowly to within 2 1/2 " and then "froze". Presently it elevated and writhed the tail. It then crawled forward cautiously to within about 1 1/2 " and froze again. There were no further tail movements. Suddenly the animal lunged forward and caught the [illegible] insect in its mouth. The tongue appeared not to have been extended. We saw other individuals use the tail movement on approaching prey. What might be its adaptive value, if any? 7th. 2 Mrs. Praphanee and her husband, Mr. Buranaphoke Kashemori, Chemistry Dept., Faculty of Medical Science, Univ. of Medical Sciences, Bangkok, drove us to Cholburi along the SE coast. We left at 8:15 a.m. and returned around 5:00 p.m. It was a clear, mild day (for this climate). We travelled in their little Volkswagen. I got many good pictures of water buffalo, including a group of them threshing rice, pictures of native huts, boats, etc.
