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.
