Like those of Wyman, the courses given by Agassiz were Senior electives. I never heard of any examination upon them; nor is it easy to imagine Agassiz as preparing a syllabus, or formulating or correcting an examination-paper. His personality and the invariable attendance of teachers and other adults precluded the necessity of disciplinary measures. But his attitude toward student misconduct was clearly shown in an incident recorded by me elsewhere.[Footnote: 'Agassiz at Penikese,' _American Naturalist_, March, 1898, p. 194. [Note by Professor Wilder.]] The method pursued by Agassiz with his laboratory students has been described by Scudder.[Footnote: See below, p. 40.] Although I was to prepare specimens at his personal expense, a somewhat similar test was applied. He placed before me a dozen young 'acanths' (dog-fish sharks), telling me to find out what I could about them. After three days he gave me other specimens, saying: 'When you go back to the little sharks you will know more about them than if you kept on with them now'--meaning, I suppose, that I should then have gained a better perspective. Although, as I recall upon several occasions, Agassiz could express his views delightfully and impressively to a single auditor, his eminently social nature and his lifelong habit rendered it easier for him to address a group of interested listeners. The following incident does not seem to have been recorded in my diary, but it is distinctly remembered. During the publication of the _Journey in Brazil_, a French translation was made by M. Felix Vogeli. With this the publishers desired to incorporate a chapter giving the latest views of Agassiz upon classification and evolution. In vain was he besought to write it. He hated writing, and was too busy. At last, in desperation, M. Vogeli came to the Museum with Mrs. Agassiz, and together they persuaded the Professor to dictate the required matter in the form of a lecture. For this, however, an audience was indispensable. The exigency was explained to the Museum staff; we assembled in the lecture-room, and the discourse began. To the dismay of some of us it proved to be in French, but we tried to look as if we comprehended it all.
