The plague of lice brought upon the Egyptians by Moses has certainly adhered to the country ever since, if “lice” is the proper translation of the Hebrew word in the Old Testament. It is my own opinion that the insects thus inflicted upon the population were not lice, but ticks. Exod. 8:16: “The dust became lice throughout all Egypt;” again, Exod. 8:17: “Smote dust… it became lice in man and beast.” Now the louse that infests the human body and hair has no connection whatever with “dust,” and if subject to a few hours’ exposure to the dry heat of the burning sand, it would shrivel and die. But the tick is an inhabitant of the dust, a dry horny insect without any apparent moisture in its composition; it lives in hot sand and dust, where it cannot possibly obtain nourishment, until some wretched animal lies down upon the spot, when it becomes covered with these horrible vermin. I have frequently seen dry desert places so infested with ticks that the ground was perfectly alive with them, and it would have been impossible to rest on the earth.
