2. Great as the differences are between the breeds of pigeons, I am fully convinced that the common opinion of naturalists is correct, namely, that all have descended from the rock-pigeon (Columba livia), including under this term several geographical races or sub-species, which differ from each other in the most trifling respects. As several of the reasons which have led me to this belief are in some degree applicable in other cases, I will here briefly give them. If the several breeds are not varieties, and have not proceeded from the rock-pigeon, they must have descended from at least seven or eight aboriginal stocks; for it is impossible to make the present domestic breeds by the crossing of any lesser number: how, for instance, could a pouter be produced by crossing two breeds unless one of the parent-stocks possessed the characteristic enormous crop? The supposed aboriginal stocks must all have been rock-pigeons, that is, not breeding or willingly perching on trees. But besides C. livia, with its geographical sub-species, only two or three other species of rock-pigeons are known; and these have not any of the characters of the domestic breeds. Hence the supposed aboriginal stocks must either still exist in the countries where they were originally domesticated, and yet be unknown to ornithologists; and this, considering their size, habits, and remarkable characters, seems very improbable; or they must have become extinct in the wild state. But birds breeding on precipices, and good fliers, are unlikely to be exterminated; and the common rock-pigeon, which has the same habits with the domestic breeds, has not been exterminated even on several of the smaller British islets, or on the shores of the Mediterranean. Hence the supposed extermination of so many species having similar habits with the rock-pigeon seems to me a very rash assumption. Moreover, the several above-named domesticated breeds have been transported to all parts of the world, and, therefore, some of them must have been carried back again into their native country; but not one has ever become wild or feral, though the dovecot-pigeon, which is the rock-pigeon in a very slightly altered state, has become feral in several places. Again, all recent experience shows that it is most difficult to get any wild animal to breed freely under domestication; yet on the hypothesis of the multiple origin of our pigeons, it must be assumed that at least seven or eight species were so thoroughly domesticated in ancient times by half-civilized man, as to be quite prolific under confinement.An argument, as it seems to me, of great weight, and applicable in several other cases, is, that the above-specified breeds, though agreeing generally in constitution, habits, voice, colouring, and in most parts of their structure, with the wild rock-pigeon, yet are certainly highly abnormal in other parts of their structure: we may look in vain throughout the whole great family of Columbidae for a beak like that of the English carrier, or that of the short-faced tumbler, or barb; for reversed feathers like those of the jacobin; for a crop like that of the pouter; for tail-feathers like those of the fantail. Hence it must be assumed not only that half-civilized man succeeded in thoroughly domesticating several species, but that he intentionally or by chance picked out extraordinarily abnormal species; and further, that these very species have since all become extinct or unknown. So many strange contingencies seem to me improbable in the highest degree.

3. Upon these clamours and complaints, the Potestates Lieutenant (beinga man of rude quality) tooke him sodainly aside, and examined him ofthe crimes wherewith he was charged. But Martellino, as making noaccount of these accusations, laughed, and returned scoffing answeres.Whereat the Judge, waxing much displeased, delivered him over to theStrappado, and stood by himselfe, to have him confesse the crimesimposed on him, and then to hang him afterward. Being let downe to theground, the Judge still demaunded of him, whether the accusationsagainst him were true, or no? Affirming, that it nothing avayled himto deny it: whereupon hee thus spake to the Judge. My Lord, I am heereready before you, to confesse the truth; but I pray you, demaund ofall them that accuse me, when and where I did cut their purses, andthen I wil tell you that, which (as yet) I have not done, otherwiseI purpose to make you no more answers.Well (quoth the Judge) thou requirest but reason; and callingdivers of the accusers, one of them saide, that he lost his purseeight dayes before; another saide six, another foure, and some saidethe very same day. Which Martellino hearing, replyed. My Lord, theyall lie in their throats, as I will plainly prove before you. Iwould to God I had never set foot within this City, as it is notmany houres since my first entrance, and presently after minearrivall, I went (in evill houre I may say for me) to see the Saintsbody, where I was thus beaten as you may beholde. That all this istrue which I say unto you, the Seigneurie Officer that keeps yourBooke of presentations, will testifie for me, as also the Host where Iam lodged. Wherefore good my Lord, if you finde all no otherwise, thenas I have said, I humbly entreate you, that upon these bad mensreportes and false informations, I may not be thus tormented, andput in perill of my life.

The treasure will be nomore mine than yours, and neither of us will quit thisprison. But my real treasure is not that, my dear friend,which awaits me beneath the sombre rocks of Monte Cristo, itis your presence, our living together five or six hours aday, in spite of our jailers; it is the rays of intelligenceyou have elicited from my brain, the languages you haveimplanted in my memory, and which have taken root there withall their philological ramifications. These differentsciences that you have made so easy to me by the depth ofthe knowledge you possess of them, and the clearness of theprinciples to which you have reduced them -- this is mytreasure, my beloved friend, and with this you have made merich and happy. Believe me, and take comfort, this is betterfor me than tons of gold and cases of diamonds, even werethey not as problematical as the clouds we see in themorning floating over the sea, which we take for terrafirma, and which evaporate and vanish as we draw near tothem. To have you as long as possible near me, to hear youreloquent speech, -- which embellishes my mind, strengthensmy soul, and makes my whole frame capable of great andterrible things, if I should ever be free, -- so fills mywhole existence, that the despair to which I was just on thepoint of yielding when I knew you, has no longer any holdover me; and this -- this is my fortune -- not chimerical,but actual. I owe you my real good, my present happiness;and all the sovereigns of the earth, even Caesar Borgiahimself, could not deprive me of this."3、预计2019年该行业市场规模为271亿元左右，到2024年市场规模增长到486亿元左右，复合增长率为12.4%。4、今天你也来尝试一下吧，当早餐当正餐都是很棒的。5、这也是真正考验业务骨干和合伙人的机会，所以，创始人在心态上首先要做到仁者不忧。
