each other, would yield the same proportions in a chemical analysis. It will be 
observed how very similar they are in composition to the solid matter suspended in 
the water of the Nile, collected by Dr. Abbott, Specimen A. 
The samples of the alluvial soils penetrated in the excavations, forwarded to me 
by Hekekyan Bey, are divisible into two classes, each offering several varieties, viz. 
into blackish brown argillaceous sandy earths, and into sands. As all of them closely 
resemble in external characters the specimens analysed, as above described (A. to M.), 
it was not deemed necessary for the object of this inquiry to have analysed 
also ; but that it would be sufficient to refer them to the analysed standard speci- 
mens. They may be thus described : —
