Last night I was thinking of this, and reasoning that as there are certain qualities in some oils which are not in others, so there may be certain similar or corresponding qualities or powers in the combinations of each.

I suppose we have all noticed some time or other that the light of colza oil is not quite the same as that of paraffin, or that the flames of coal gas and whale oil are different.

They find it so in the light-houses! All at once it occurred to me that there might be some special virtue in the oil which had been found in the jars when Queen Tera's tomb was opened.

These had not been used to preserve the intestines as usual, so they must have been placed there for some other purpose.

I remembered that in Van Huyn's narrative he had commented on the way the jars were sealed.
This was lightly, though effectually; they could be opened without force.
