columbarium

Their sides present the well-known appearance of the Roman columbaria (dove-cotes), but with the important difference, that they are adapted to contain coffins instead of urns, the holes being about 2 feet square and 6 feet deep.

We have seen how it is originally language which works on the construction of concepts, a labor taken over in later ages by science. Just as the bee simultaneously constructs cells and fills them with honey, so science works unceasingly on this great columbarium of concepts, the graveyard of perceptions.
