_Mrs. B._ Perhaps not, my dear; but nothing that is valuable, can be attained without difficulty. I would wish to smooth the path for you as much as I can, but learning is "labour, call it what you will;" and without strict attention, and industrious perseverance, you will never attain perfection in any thing. The classes and orders in that division of natural history, called the animal kingdom, are, however, by no means difficult. There are, in botany, as you no doubt recollect, twenty-four classes; in natural history, there are but six. "Will you be so kind as to repeat them to us, mamma?" said Louisa. _Mrs. B._ Willingly, my dear. The first is called Mammalia, and consists of Quadrupeds and Whales; the second, Birds; third, Amphibia; fourth, Fishes; fifth, Insects; and sixth, Worms. _Louisa_. That seems very easy. I think I could soon learn those six classes. Are there many orders, mamma? _Mrs. B._ In the class Mammalia there are seven. But we must not talk of them just at present, or our Roman history will be forgotten. _Edward_. Before we change the subject, will you be so good as to tell me, mamma, what you meant by saying, that division of natural history called the animal kingdom. Are there, then, many divisions? _Mrs. B._ There are three, my dear. The first consisting of Minerals; the second, of Vegetables; and the third, of Animals. _Mr. B._ Well, my dears, now do not forget what you have been already told, and another day we will talk further on this subject: for the present, let us attend to our history. We concluded with the death of Ancus Martius. Who succeeded to the crown, Emily? _Emily._ Lucius Tarquinius Priscus. He was the son of a merchant of Corinth, which is a large city of Greece. This man had acquired a considerable fortune by trade, which was inherited by his son Lucumo, who took the name of Tarquinius, from Tarquinia, a city of Hetruria, where his wife Tanaquil lived, previous to her marriage. His birth being considered contemptible by the nobles of this place, he, by his wife's persuasions, settled in Rome, where merit alone gave distinction. _Mr. B._ What remarkable circumstance is said to have occurred to him on his way thither, Ferdinand? _Ferdinand._ As he approached the city gate, historians say, that an eagle, stooping from above, took off his hat, and, after flying round his chariot for some time, with a great noise, put it on again. From this circumstance, his wife, Tanaquil, foretold that he would one day wear the crown. _Mr. B._ By what means, Edward, did he obtain this object of his ambition?
