ABSTRACT

The line of demarcation between the vegetable and animal kingdoms is so obscurely marked in the lowly organized marine species, and the modes of collecting and preserving these are so similar. In collecting algae, corallines, or the branched, horny, or calcareous corals, care should be taken to bring the entire specimen with its base or root. With respect to the coarser algae, it is merely requisite, for the purpose of transmission, to spread the specimens immediately on being brought fresh from the sea, without previous washing, in an airy situation to dry. Where the sea seems pure and colourless a bucketful may be raised and strained through fine linen; by repeating the act a portion will commonly remain on the filter, which is then generally rich in invisible animalcules, and should be preserved in small glass bottles or tubes, with a bubble of air between the cork or stopper and the water.
