To quickly assess the difficulty of the text, read a short excerpt:
But unfortu- nately these highly civilized animals are not related to us. Our next task must now be, to enter in greater detail into the vertebrate nature of Man, and to determine the special position which he holds in the system of Verte- brates. Here it is necessary to point out the most essen- tial facts in the particular structure of the vertebrate body; for, otherwise, we shall be quite unable to enter rightly into the difficult question of Ontogeny. The evolu- tion of even the simplest an...d lowest Vertebrate from the simple Gastrula is so complex a process, and is so difficult to trace, that it is necessary to understand the principles of the organization of the perfect Vertebrate, in order to comprehend the principles of its evolution. But it is equally important that in this brief anatomical description of the vertebrate organism, we should stop only at the essential facts, and leave all others untouched. Therefore, in giving an ideal anatomical sketch of the main form of the Verte- brate and its inner organization, I leave out all secondary and non-essential circumstances, and confine myself to those most essential.
