[Nov. 19, 



Sand. — Mostly angular or subangular. Only a few well-rounded 

 grains. Consists of quartz (granitic), with a few particles derived 

 from metamorphic rocks. Microcline and orthoclase, but only 

 very slightly kaolinised; plagioclase-felspar, hornblende, augite C?), 

 sphene (?), magnetite ; with red, brown, and black jasper. 



Mud. — As in last. 



Sample 5. Depth, 40 ft. 6 in. 



Sandy loam. Consists of 80*83 per cent, sand, 19*17 per cent, 

 mud. 



Sand. — Consists of about equal proportions of rounded and of 

 angular or subangular grains. The materials are quartz, with fine 

 inclusions of .rutile, apatite (?), &c, with bands of liquid and gas 

 cavities, microcline and orthoclase (slightly kaolinised), plagioclase- 

 felspar, hornblende, red, brown, and black jasper, glauconite (?) 

 grains. 



Mud. — As in last. 



Sample 6. Depth, 45 ft. 



Sandy loam. Consists of 68*72 per cent, sand, 31*28 per cent, 

 mud. 



Sand. — The angular and subangular particles preponderate over 

 the rounded ones. The minerals represented are quartz (granitic), 

 with hair-like inclusions (rutile), quartz of metamorphic origin, 

 microcline and orthoclase (slightly kaolinised), plagioclase-felspar, 

 hornblende, and biotite. Also red, black, brown, and green jasper. 



Mud. — As in last. 



II. Boring at Kafr-ez-Zayat. 



Sample 1. Depth, 3 ft. 



Mould of yellowish -brown colour. Consists of 2*35 per cent, sand, 

 and 97 65 mud. 



Sand. — Mostly angular or subangular, but a few well-rounded 

 grains present. Consists of grains of quartz (granitic), with many 

 acicular crystals inclosed, and bands of cavities. Fragments of 

 hornblende abound. Orthoclase and a little plagioclase-felspar, 

 jasper, and small calcareous concretions. Vegetable matter. 



Mud. — Contains much organic matter. Frustules of diatoms. 



Sample 2. Depth, 4 ft. 



Light coloured, sandy loam. Consists of 30*42 per cent, sand, 

 69*58 per cent. mud. 



Sand. — About an equal admixture of rounded with angular or
