1825: Letter from David Porter to Major Mordecai M. Noah

Meridian Hill, 18th Sept. 1825.    

Dear Sir:

  By means of epistolary introduction I have had the pleasure of becoming acquainted with John H. I. Browere, Esq., a young and deserving artist of your city. Agreeably to your and my friends' requests, I consented to sit for my portrait bust, which has been executed by him according to his novel and perfect mode. Mr. Browere has succeeded to admiration. Nothing can be more accurate and expressive; in fact, it was impossible that it could be otherwise than a perfect facsimile of my person, owing to the peculiar neatness and dexterity which guide his scientific operation. The knowledge and dexterity of Mr. Browere in this branch of the Fine Arts is surprising, and were I to express my opinion on the subject, I should recommend every one who wished to possess a perfect likeness of himself or friends to resort to Mr. Browere in preference to any other man. His portrait busts are chef d'oevres in the plastic art, unequalled for beauty and correct delineation of the human form. To those to whom a saving of time is important, Mr. Browere's method must receive the preference, were it solely on that ground. As to the effect of the operation, none need apprehend the least danger or inconvenience; it is perfectly safe and not disagreeable, for while the plastic material is applying to the skin, a sensation both harmless and agreeable produces a pleasant glow or heat somewhat similar to that which is felt on entering a warm bath; neither does the composition affect the eyes, which are covered with it. Too much commendation of Mr. Browere's rare and invaluable invention cannot be made. May he derive benefits from his art equal to his merit. Hoping to have the pleasure of seeing my friends in New York during the course of a few weeks, I remain, Dear Sir,

Your obt. servant

David Porter.
