Professor Theodore G. Wormley, in the new edition of his work, gives the
following sizes of blood corpuscles, as measured by himself and
Professor Gulliver. We have only copied the sizes for mammals and birds.
It will be seen that, with three or four exceptions, the sizes obtained
by the two observers are practically the same:

The subject of minute measurements was discussed in an interesting
manner in an address before the Microscopical Section of the A.A.A.S.
last year, an abstract of which was published in this journal, vol. v.,
p. 181.
The slight differences in size accurately given in this table are not
always appreciable under modern amplification, but under a power of
1,150 diameters "corpuscles differing by the 1-100000 of an inch are
readily discriminated." For the conclusions of Prof. Wormley as regards
the possibility of identifying blood of different animals, the reader is
referred to his book on Micro-Chemistry of Poisons.--_Amer. Micro.
