SOME RECENT RESEARCHES IN THE QUARTERNARY BEDS OE 
MARIGNAC IN THE COMMUNE OF TAURIDE, GIRONDE, ERANCE. 
A paper read before the Linnean Society of Bordeaux, by 
Francois Daleau, presents some interesting recent discoveries 
made by that indefatigable explorer. 
The quaternary alluvial deposits in many localities of the 
cantons of Bourg and Saint Savin have long been exploited at 
different altitudes for building sand and road gravel. His excava- 
tions in the sands of Sexcommunes had, until recently, not brought 
to light any finds except fossil wood, i. e., the silicified trunk of 
a tree that undoubtedly had been washed out of a lower formation 
by quaternary waters. In 1870, however, an incomplete maxillary 
and two teeth of an undetermined elephant taken from the sand 
of the left bank of the Dordogne River were given him, but with- 
out information as to the particular quarry whence they were 
taken. In 1889 he found m situ in a pit in Marignac, some flint 
implements shaped by man. The depth of the excavation reached 
7 1-15 metres (30 feet) below the surface, penetrating the recent, 
middle and lower quaternary strata for 18 feet, and the upper 
and lower Tongrien beds of the Tertiary 12 feet or more. 
The following relics were found in the neolithic strata, as 
defined by G. de Mortillett's schedule : A black flint nucleus ; a 
quartzite hammer showing traces of battering ; an oval, stationary 
mill, much used on both sides, all of the Solutreenne and Mada- 
luneenne forms. In the middle Quaternary, ten bulbose and con- 
choidal flint flakes, due to a peculiar percussion characteristic of 
the Monsterienne period ; a Monsterienne kind of pointed flint 
scraper chipped only on one side, covered by a white patine; and 
a very pretty small Acheuleen (perfected Chelleen form) flint 
implement, finely chipped on both sides, with a white patine on
