    Notes: [Auszug] I HAVE read with interest Mr. Jones's letter on the results of the application of the logarithmic series and the index of diversity to his quadrat observations. I completely agree with him that the theoretical basis requires further study; as also does the field application to both animals and ...

    Notes: [Auszug] THERE have recently been two attempts to study the problem of random sampling from a mixed population in which all the constituent groups are not equally abundant. R. A. Fisher1 studied the problem of random samples of a population of insects in which the species were not equally ...

    Notes: [Auszug] IN the course of some experimental work on insects which we have been carrying out, it was necessary to have a large number of constant temperatures. As it was impossible to have a complete incubator for every temperature, an incubator was designed by Mr. T. W. Kirkpatrick and myself to give a ...

    Notes: [Auszug] IN the issue of NATURE for June 17 there is a discussion on the inadequacy of present observations on the sense of smell in birds.

    Notes: [Auszug] YOUR engraver has snissed what I thought the most important feature in the drawings which I made of the comet on the 21st inst., viz, the shadow beyond the end of the tail, of the length of 3 or 4 degrees, very obviously darker than the surrounding space, in which it was lost, without ...

    Notes: [Auszug] IN the morning here the sky was clear, and the sun remarkably free from spots. I noticed only 4 small ones on the disk: quite a contrast to the monstrous appearance a month ago. Being neither equipped nor qualified for technical astronomical observations, I did not attempt to do more than ...

    Notes: [Auszug] FOR several mornings past we have had fine views of the comet, first seen in England by Mr. A. Common. I inclose a sketch taken this morning, as accurate as I could make it with materials at hand. It is chiefly remarkable (1) for the crescentic end of the tail, the lower or eastern horn ...
