The evidence of these statements will be presently given; but meantime it may be remarked that such grand results redeem the study of microscopical objects from that pettiness which is often imputed to it.
Page 23 - Yet this is exactly what these jellyspecks do on a most minute scale; the tests they construct when highly magnified, bearing comparison with the most skilful masonry of man.
