 VOLCANIC MUD : gritty, fine-grained, incoherent ; has the appearance of 

 having been washed ; contains pelagic and bottom-living Foraminifera, Echi- 

 noid spines, Polyzoa, small Mollusc shells, Pteropods, Heteropods ; minerals 

 abundant, angular, mean diameter 0.1 mm., augite, palagonitic matter, 

 olivine, plagioclase, chloritic mineral, biotite, much magnetite. 



Station 183, 24th November, 1899. 

 Lat. 19° 4' S. ; long. 167° 41' W. ; depth, 2472 fathoms. 



EED CLAY: very little material, incoherent, apparently washed, consist- 

 ing of angular mineral particles, mean diameter 0.1 mm., felspar, obsidian, 

 pumice, magnetite, and manganese, small rock particles about 1 mm. in 

 diameter, Kadiolaria, Fish teeth. 



Station 184, 26th November, 1899. 

 Lat. 20° 15' S. ; long. 172° 0' W. ; depth, 3141 fathoms. 

 RED CLAY : almost black in color, slightly coherent ; may have been 

 washed, as the percentage of minerals is quite 70 per cent of the whole 

 sample ; con.sists of ani^ular mineral particles, mean diameter 0.15 mm., 

 olivine, augite, volcanic glass, magnetite, palagonite, plagioclase, cosmic 

 spherules.

 contains about 40 per cent of angular mineral particles, mean diameter 

 0.2 mm., one piece of pumice 1 cm. in diameter, brown volcanic glass abund- 

 ant, augite, plagioclase, magnetite ; Radiolaria, and Sponge spicules.
