At the conclusion of these remarks a set of resolutions was read by Bishop Potter.[15]They were followed by a few little friendly speeches, all made in the most informal and cordial spirit; and so ended our course of lectures on board the Colorado. Later in the day we observed singular bright red patches in the sea. Some were not less than seven or eight feet in length, rather oblong, and the whole mass looked as red as blood. Sometimes they seemed to lie on the very top of the water, sometimes to be a little below it, so as only to tinge the rippling surface. One of the sailors succeeded in catching a portion of it in a bucket, when it was found to consist of a solid mass of little crustaceans, bright red in color. They were all very lively, keeping up a constant rapid motion. Mr. Agassiz examined them under the microscope and found them to be the young of a crab. He has no doubt that every such patch is a single brood, floating thus compactly together like spawn.
