To quickly assess the difficulty of the text, read a short excerpt:
The animal structures of the sea-water must now, however, claim our attention. Amongst the lowest form of animal life are the sponges. They are frequently cast on the shore with sea-weeds, and afford interesting objects for the Microscope. They are composed of animal matter, which lies upon a structure of horny, calcareous, or sili- ceous matter. The common sponge which is used for domestic purposes may be taken as a type of the whole group. If a thin section of the common sponge is made with a... pair of sharp scissors and placed under a low power, it will be seen to be composed of a network of horny matter, repre- sented in figure 140, plate 5. If now we take one of the common forms from our own sea-shore, we shall find that the network is composed of sili- ceous spicules lying one over the other, as repre- sented in figure 141 of plate 5. If one of these spicules is examined (a) and compared with a spicule from another sponge, it will be found to differ in form and size ; and the species of sponges can actually be made out by the shape of their spicules.
