Thus we find this string of authorities, when examined to the beginning, all hanging on the same hook, a perverted expression of Prisot's, or on one another, or nobody. Thus Finch quotes Prisot; Wingate also; Sheppard quotes Prisot, Finch and Wingate; Hale cites nobody; the court in Woolston's case cite Hale; Wood cites Woolston's case; Blackstone that and Hale; and Lord Mansfield, like Hale, ventures it on his own authority. In the earlier ages of the law, as in the year-books, for instance, we do not expect much recurrence to authorities by the judges, because in those days there were few or none such made public. But in latter times we take no judge's word for what the law is, further than he is warranted by the authorities he appeals to. His decision may bind the unfortunate individual who happens to be the particular subject of it; but it cannot alter the law. Though the common law may be termed "Lex non Scripta," yet the same Hale tells us "when I call those parts of our laws Leges non Scriptæ, I do not mean as if those laws were only oral, or communicated from the former ages to the latter merely by word. For all those laws have their several monuments in writing, whereby they are transferred from one age to another, and without which they would soon lose all kind of certainty. They are for the most part extant in records of pleas, proceedings, and judgments, in books of reports and judicial decisions, in tractates of learned men's arguments and opinions, preserved from ancient times and still extant in writing." Hale's H. c. d. 22. Authorities for what is common law may therefore be as well cited, as for any part of the Lex Scripta, and there is no better instance of the necessity of holding the judges and writers to a declaration of their authorities than the present; where we detect them endeavoring to make law where they found none, and to submit us at one stroke to a whole system, no particle of which has its foundation in the common law. For we know that the common law is that system of law which was introduced by the Saxons on their settlement in England, and altered from time to time by proper legislative authority from that time to the date of Magna Charta, which terminates the period of the common law, or lex non scripta, and commences that of the statute law, or Lex Scripta. This settlement took place about the middle of the fifth century. But Christianity was not introduced till the seventh century; the conversion of the first Christian king of the Heptarchy having taken place about the year 598, and that of the last about 686. Here, then, was a space of two hundred years, during which the common law was in existence, and Christianity no part of it. If it ever was adopted, therefore, into the common law, it must have been between the introduction of Christianity and the date of the Magna Charta. But of the laws of this period we have a tolerable collection by Lambard and Wilkins, probably not perfect, but
