I34i IMPROVED CAPSTAN AND WINDLASS.

 idea to me is quite new.

 To Mr. BoswELL. 



SIR, 



Accovding to j^our desire, I transcribe the part of the let- 

 ter from Mr. Peake (Surveyor of the Navy) to me, which 

 relates to the capstan laid before the Society.

 *' hitherto have been foiled, and shall more readily forward 

 *' it, if it was only to supersede a plan now creeping into 

 ** the service, more expensive, and much worse than one 

 *' lately exploded."

 letter, I imagine further attestation needless relative to it.

betwixt each crossing. I add this because one of the gen- 

 tlemen of the Committee wished to be informed on this 

 point. 



I am, Sir, 



Your very respectful humble servant, 



J. W. BOSWELL. 



SIR,

 tion of the advantages to be obtained by the use of capstans 



made
