Ratio of Consecutive Fibonacci Numbers/Historical Note

Historical Note on Ratio of Consecutive Fibonacci Numbers
This result was observed by, but not established rigorously by him:
 * It is so arranged that the two lesser terms of a progressive series added together constitute the third ... and so on to infinity, as the same proportion continues unbroken. It is impossible to provide a perfect example in round numbers. However ... Let the smalllest numbers be $1$ and $1$, which you must imagine as unequal. Add them, and the sum will be $2$; add this to $1$, result $3$; add $2$ to this, and get $5$; add $3$, get $8$ ... as $5$ is to $8$, so $8$ is to $13$, approximately, and as $8$ is to $13$, so $13$ is to $21$, approximately.

However, it was in $1753$ who first explicitly stated that the Ratio of Consecutive Fibonacci Numbers tend to a limit.
