|Title||Classified papers: volume 3i concerning 'Mechanicks, Trades, Engineering, Navigation'|
|Description||Papers on mechanics, trades, engineering and navigation. These works were either sent to the Royal Society, usually by their authors or by intermediaries, for reading at ordinary meetings of the Royal Society. Material might be commissioned by the Royal Society, or collected by other means.|
The volume has a manuscript listing bound into the front of the book. This notes the paper number (1-68).
|Extent||One volume containing 68 papers.|
|Physical description||Volume quarter bound in cream leather with tan cloth boards|
|Notes||The final papers concerning trade are of some interest in that they date from the first half of the 17th century, and were presumably acquired from a different source.|
