VOYAGE FROM NEW YORK TO RIO DE JANEIRO. 45 



intellectual capital to which she has a right. Publish 

 your results at home, and let Europe discover whether 

 they are worth reading. Not until you are faithful to 

 your citizenship in your intellectual as well as your po- 

 litical life, will you be truly upright and worthy students 

 of nature," 



At the conclusion of these remarks a set of resolutions 

 was read by Bishop Potter.* 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.
