There follows a detailed and loving description of the animal inhabiting the shell, which I must reserve for a future edition. Of another species of snail, Helix strigata, our learned author observes that "This shell is, when dead, one of those which is found on the banks of the Tiber. It is a strange circumstance that, although it is a land shell, it should be found more on the banks of a river than anywhere else, and also only on the banks of the Tiber, for it is not found on the banks of any other river. Any one would think that dead shells were gifted with the power of walking about, for certainly it is an inexplicable wonder how they got there." Of Helix muralis we are informed that "The Romans eat these snails, not the whole of them, but only their feet. In ancient times the most wealthy people used to eat snails, and perhaps they ate the very ones which the poorest people eat nowadays. It is most probable, for there are a great many different kinds of snails round Rome, and the Romans would probably select the best." I may perhaps be permitted to remark that the correct orthography of this writer fills me with astonishment, inasmuch as in later life I have reason to know that he often went astray in this respect. Of the uniform maturity of the literary style, I have no need to speak. Eddy's father was in the habit of giving him an income of two or three pauls a week, dependent on his good behavior and punctual preparation of his lessons; and since Eddy was always well behaved and faithful in his studies, the income came in pretty regularly. Eddy saved up this revenue with a view to buying himself a microscope, for the better prosecution of his zoological labors; being, also, stimulated thereto by the fact that I already possessed one of these instruments, given me by my father a year or two before. Mine cost ten shillings, but Eddy meant to get one even more expensive. I had, too, a large volume of six hundred pages on The Microscope, Its History, Construction, and Uses, by Jabez Hogg, the contents of which I had long since learned by heart, and which I gladly communicated to my friend. At length Eddy's economies had proceeded so far that he was able to calculate that on his twelfth birthday he would possess a fortune of five scudi, and he decided that he would buy a microscope at that figure; it is needless to add that the microscope had long since been selected in the shop, and was decidedly superior to mine. We could hardly contain our impatience to enter upon the marvellous world whereof this instrument was the key; that twelfth birthday seemed long in coming, but at last it came.
