 Dear Sir,


 I have been writing somewhat for 
 the essay, such I suppose it might be called, and
 find it rather more difficult than I had anticipated—
 ’Tis harder to suit myself as to arrangement and
 composition, and to think it will suit others
 equally well, than I would be to take an
 original subject and write a like number of 
 pages upon it. By tuesday I may be able
 to show you some progress, you can then prune
 or cast aside at your good will & pleasure. I’m
 sure you’ll be obliged to do it freely, if not to
 reject the whole. If I could see the rest of
 the “Geography” it would be better than anything
 else as a guide Dr Pickeding’s Chapter is too elaborate
 and embodies more information than I possess,
 beside it is much longed and more scientific
 than is wanted here.


 Mr. Holton says Mr Schaeffer’s experiments
 will not be ready until some time next week,
 you will of course not be in the City until that
