sciences which he himself had studied, probed, taught, and popularized.

It will be remembered how patiently he devoted himself for twelve years to
the study of madder, multiplying his researches, and applying himself not
only to extracting the colouring principle, but also to indicating means
whereby adulteration and fraud might be detected.

He had published memoirs of great importance dealing with entomology in its
relations to agriculture. Impressed with the importance of this little
world, he suggested valuable remedies, means of preservation; which were

efficacious, must be based not upon a gross empiricism, but on a previous
study of their social life and their habits.

With what patience he observed the terribly destructive weevils, and those

whose depredations have often been valued at millions of francs! How

Slowly, however, the first instalment of the work which he had spent nearly
