ring, which it resembles. The thorax of the Diptera is con- 
structed like that of the Lepidoptera, though the latter have a 
mesophragma divided longitudinally, and the former an entire 
diaphragm. 
Prof. A. Lacassagne (“ Revue Scientifique ”) gives an assay 
on “ Criminality in Animals ” which coincides very closely with 
our article on “ Animal Depravity” (“ Journal of Science,” 1875, 
p- 415)- 
M. Millet, in a paper read before the Societe d’Acclimatation, 
gives some interesting particulars concerning the stork. The 
male arrives first to take possession of the old nest, and the 
female follows some days later. If frost or damp is expedled the 
male covers his brooding mate with dry grass. The number of 
young brought out is generally five. The stork arrives in France 
on an average about March 24th, and leaves about August 12th. 
Attempts are being made to acclimatise in France Pucrasia 
macrolopha, a bird nearly allied to the true pheasants, but sur- 
passing them in the quality of its flesh. 
Mr. F. Cope Whitehouse makes the startling assertion that 
Fingal’s Cave is probably an artificial excavation. His argu- 
ments are entitled to serious consideration. 
Mr. Horatio Hale, in a paper read at the late meeting of the 
American Association for the Advancement of Science, suggests 
that the Red Indians of America were originally immigrants 
from Europe. 
According to the “ Popular Science Monthly,’’ “the degree of 
barbarism in any community is measured by the impunity with 
which its members seek their gratification at each other’s 
expense.” This is a home-thrust for dog owners. 
Messrs. Mawson and Swan have made a small accumulator 
weighing about five pounds, which is capable of working one 
lamp continuously for two hours when fully charged, or for a 
much longer time by turning off the light when not wanted. 
Irrespective of the use of the eledlric lamp for illuminating pur- 
poses, in combination with very sensitive dry plates, it be all 
that is required for the taking of micro-photographs. 
At a recent conversazione of the Royal Microscopical Society, 
an adaptation of the incandescent light was exhibited by Messrs. 
Mawson and Swan, of Newcastle. The carbon loop was 
enclosed in a very small tube, which enabled the light to be 
brought quite close to an opaque objedl, which was thus illu- 
minated without any assistance from a condensing lens. On 
another microscope the light was placed close beneath the objedl, 
and was attached to a simple contrivance, which enabled it to be 
rotated eccentrically to the axis of microscope : in this case a
