As this specimen was obiaiued ee a part of the Lake not very 
distant from the focus of the detrital deposits, it may be regarded as ex- 
hibiting the maximum of the most transportable matter and the mini- 
mum of the least. Yet the orbits of lime exceeds the silica only in 
the ratio of 7 to 6. As the ratio of the lime to the silex in the detritus
