Samuel Sturmy, in his Mariners Magazine ... of 1669 wrote:

"Master Gunters Chain is a Chain most used amongst
the Surveyors of this Age, and is always made to contain
4 Poles, and each Pole 25 Links, and each Link 7 inches
92/100 of an Inch. In measuring with this Chain you are
to take notice of only Chains and Links, saying, such a
Line measured by the Chain contains 64 Chains 45 Links,
or thus distingquished 64. 45."

There were other types of chains in use, such as Rathborne's
in which each pole or perch was divided into 100 links, and Wing's
in which each pole consisted of 20 links.
