Page 426 - Unlike cochineal, the new dye discovered at Kingston is a native Canadian product, and capable of being produced in temperate countries. Having been but recently observed, a sufficient quantity has not yet been obtained for a complete series of experiments as to its nature and uses ; but the habits of the insect, as well as the properties of the dye, seem to indicate that it may become of practical importance. In colour it closely resembles ordinary cochineal, having rather more the scarlet hue of...

The true lines of the 30th band we were unable to see, at least with any degree of certainty, still, from indications, we have no doubt they are ruled as stated by Nobert.
Page 212 - Robert's registration on the plate as given in the first table above. Such discrepancies are to be expected, and by microscopists familiar with operations of this kind, are looked upon as unavoidable ; but that on the 25th band is rather large to be accounted for in this way. We are unable to explain it, and can only say that our repeated measurements of it were very carefully made. These experiments, together with those of others before noticed, induce us to believe that the limit of the resolvability...
Page 213 - Many frustules of these species, from different localities, have been measured by us and always with the same results. Pleurosigma fasciola has been specially designated by Mr. Sollitt, and also by Dr. Wallich, as very inconstant in its markings. Of this diatom we are fortunate in being supplied with abundant specimens, from various localities in England, particularly from the neighborhood of Hull.
Page 468 - I am sorry to be the dispeller of such agreeable delusions; but the gorilla does not lurk in trees by the roadside, and drag up unsuspicious passers-by in its claws, and choke them to death in its vice-like paws; it does not attack the elephant, and beat him to death with sticks; it does not carry off women from the native villages; it does not even build itself a house of leaves and twigs in the forest-trees and sit on the roof, as has been confidently reported of it. It is not gregarious even,...
Page 211 - The figures in the 3d and 6th columns, showing the distance apart of the lines in each band, are the mean of numerous and slightly variant trials, particularly on the higher bands. Up to the 26th band there was no serious difficulty in resolving and ascertaining the position of the lines, but on this and the subsequent ones, spectral lines,* that is, lines each composed of two or more real lines, more or less prevailed, showing that the resolving power of the objective was approaching its limit....

A similarly uniform striation has always been observed among the individuals of many other species examined by us. To such uniformity of striation Amphipleura pellucida forms as yet no exception ; this diatom is still a "res vexata" among microscopists ; neither the striation nor the structure of its frustule is at all satisfactorily understood.
