At the latter, the first cast of the large dredge was made on a ledge of shoals in a depth of eighty fathoms, and, among countless other things, a number of stemmed crinoids and comatulae were brought up. An ardent student of the early fossil echinoderms, it was a great pleasure to Agassiz to gather their fresh and living representatives.
Agassiz believes that they have not even affected the geographical range and the actual association of species, still less their forms; but that every adaptation of species to climate, and of species to species, is as aboriginal, and therefore as inexplicable, as are the organic forms themselves.
What then are the earliest known vertebrates? He closes the article from which these quotations are taken with the assertion, "that there is no evidence of a direct descent of later from earlier species in the geological succession of animals." It will be observed that Agassiz is quoted, not as to matters of theory, but as to matters of fact.
To this date belongs a short correspondence between Agassiz and Oswald Heer. Heer's work on the Fossil Flora of the Arctics had recently appeared, and a presentation copy from him reached Agassiz as he was slowly regaining strength after his illness, although still confined to the house.
He was known in all the museums of Europe as an indefatigable worker and collector, seeking everywhere materials for comparison. Among the letters of this date is one from Charpentier, one of the pioneers of glacial investigation, under whose auspices, two years later, Agassiz began his inquiries into glacial phenomena.
Homer and the later Greeks, some of the Romans and early Christians held this view the last believing that God sent angels in the shape of birds to comfort sufferers for the faith. St. Francis called the birds and beasts his brothers. Dr. Johnson believed in a future life for animals, as also did Wordsworth, Shelley, Coleridge, Jeremy Taylor, Agassiz, Lamartine, and many Christian scholars.
He told me once of having recounted to Agassiz the facts of a very remarkable seance, where the souls of the departed outdid themselves in the athletics and acrobatics they seem so fond of over there, throwing large stones across the room, moving pianos, and lifting dinner-tables and setting them a-twirl under the chandelier. "And now," he demanded, "what do you say to that?" "Well, Mr.
The next is in answer to a letter from Agassiz to the veteran naturalist, Professor Sedgwick, concerning casts of well-known fossil specimens in Cambridge, England. Though the casts were unattainable, the affectionate reply gave Agassiz keen pleasure. THE CLOSE, NORWICH, August 9, 1871.
Agassiz has attempted to give definiteness to the terms above enumerated, which have been used with various significance, by limiting each one of them to covering a single category of natural relationship. Thus: Branches or types are characterized by their plan of structure. Classes, by the manner in which that plan is executed, so far as ways and means are concerned.
Agassiz himself could not have hit off better the salient characteristics of the little creature in question. Had that remarkable boy been brought into contact, for five minutes only, with Julius Caesar, who can doubt that the telling description he would have given of him would have come down through all the ages?
