282 OF MAKING AN

 before the public. We are obliged to the editor for 

 preserving these valuable though crude materials, and 

 he has shown ability in digesting and elucidating them. 

 I should scarcely, for my own part, have thought it 

 right to furnish still more crude and imperfect guesses 

 and opinions, from manuscripts which their illustrious 

 author had purposely, as it appears, withheld from his 

 auditors, lest he should lead them into error. This
