-One of the most agreeable works that has found its way to our table, from London of late, is C. Piazzi Smyth's " Teneriffe, an Astronomer's Experiment; or Specialities of a Residence above the Clouds." It is illustrated with Photo Stereoscopic views, the first book of the kind. Mr. Smyth and his suite passed some months near the summit of the peak of Teneriffe in astronomical observations, and has made a popular narrative of the expedition, in which he was accompanied by his wife. He appears to have been an enthusiastic naturalist as well as astronomer. We can find room only for the following extracts:

" We were travelling now over rough ground of volcanic rubbish, loose cinders, and one would think in such constant motion that no plants could retain a footing. Nor can any one of them do so except the Cytisus Nubigenus, and that rejoices in the site and flourishes. How wonderful the adaptations of nature to the necessities of different regions. For here, where the ceaseless motion of the sliding particles composing a hill.side, destroys every other living thing; where the aridity of the soil during many months is only surpassed by the aridity of the air, which is dryer than that of Sahara, nature has produced a plants that on the mere remembrance of winter rain, long since evaporated, can furnish no contemptible supply of wood; and with its richly stored, white flowers, arranged in close rows along its smaller branches, affords illimitable honey-making materials to all the bees of the country. The inhabitants of the lower strata fasten their bee-hives on mules, and pasture their bees here every summer......

"The great Dragon Tree, Dracaena Draco, to which most sober naturalists attribute the age of 6000 years, proudly raises its antique arms above every thing around, with its enormous root like branches, and is now well cared for by a Spanish nobleman who has purchased the place where it grows".
