On taking a petrel out of its nest, it would not at first, onbeing set down, attempt to fly; but would endeavour to dig and shuffle its wayinto one of the broken holes. The nests are made in the angles of galleries,about six inches below the surface and parallel with it. Each nest has at least twoways of access to it. It is formed with a little dry grass, and kept very clean.The petrel uses its beak in these excavations like a pick-axe, and throws the looseearth behind it by kicking alternately with each foot.

They appear in their burrows on Green Island about themiddle or latter part of April.

TEE INTELLECTUAL OBSERVER. JANUARY, 1865. CELESTIAL CHEMISTRY, AND THE PHYSICALCONSTITUTION OF THE STARS AND NEBULA. BY THOMAS W. BUBE, E.R.A.S., P.C.S.(With a Coloured Plate.) Few things are more remarkable in the present aspect ofscience than the manner in which its various departments comeinto contact one with another, thus aiding the student in away quite unlooked for, and throwing light upon the subjectof research from a quarter whence it was least expected.As when stones are thrown into water, so the circle of eachscience at first seems to be totally distinct from all the others,but gradually these separate circles enlarge and widen, untilthey intersect and produce larger circles and wider generaliza-tions in the increasing domain of human knowledge. Thus,chemistry was, in the time of Davy, furnished with a new andpowerful analytical agent in the shape of voltaic electricity, andthe same agency, which is itself evoked by chemical action, hasgiven us the long series of discoverie
