ABSTRACT
l. 18] ‘The dust which overspreads these beds of sand is so fine, that the lightest animal, the smallest insect, leaves there as on snow, the vestiges of its track. The varieties of these impressions produce a pleasing effect, in spots where the saddened soul expects to meet with nothing but symptoms of the proscriptions of nature. It is impossible to see any thing more beautiful than the traces of the passage of a species of very small lizards extremely common in these desarts. The extremity of their tail forms regular sinuosities, in the middle of two rows of delineations, also regularly imprinted by their four feet, with their five slender toes. There traces are multiplied and interwoven near the subterranean retreats of these little animals, and present a singular assemblage which is not void of beauty.’ Sonnini. 248
