Theodatus Garlick was recorded in one announcement that appeared on October 22, 1840 in The Pilot and Transcript (Baltimore, Maryland).  The Daguerreotype.—Cheaper Plates.—In the number of the Maryland Medical and Surgical Journal, just issued, is a communication from Doctor Theodatus Garlick, of this city, detailing the preparing daguerreotype plates in a simpler and cheaper manner than that now used, in obtaining photognic drawings.  Doctor Garlick takes a plate of sheet brass, or copper, well planished, to make it very dense.  This he polishes highly, by using first, fine pumice stone and oil, which gives a tolerably fine and regular surface; then rotten stone and oil, which improves it considerably.  The plate is next cleansed by washing or wiping, when it must be finished very highly by the buff with the peroxide of iron without oil.  The plate must be as bright as a mirror to produce a fine picture.  It is now ready for silvering.  “Make a weak solution of the nitrate of silver, which must be applied equally over the surface of the brass with a camel’s hair brush.  The silver is instantly precipitated, and adheres to the plate very firmly, in the form of a dark brown powder.  The surface should then be rubbed over gently with a super-tartrate of potash, made moist with water, which restores it to its bright color.  The successive application of the solution of the nitrate of silver, and the super-tartrate should be repeated at least three times.  The solution of the nitrate should not be to strong, as it then corrodes the brass, and the silver will come off in flakes.  The best criterion is to try the solution upon the edge of the plate.  If it turns the plate instantly black, it is too strong.  It should produce a deep brown color, or that rather gradually.  You may take another buff, (which should be used for no other purpose, and must be soft,)  and a little very fine peroxide of iron, and polish the plate, finally as high as possible.  The buff should pass over the plate transversely, instead of circularly, as recommended by M. Daguerre, so that the marks it leaves should run all one way.  It is now [ready] for the iodine.”  We have used the Doctor’s own words, in giving the process of preparing a plate.  He says it is easily accomplished, after a little practice, and takes but little time.—Plates prepared in this way, he says, are capable of producing the finest specimens of daguerreotype drawings.

A Second Self.—We spent a few moments in the room of Mr. Garlic this morning, just long enough to see a gentlemanly bachelor of our acquaintance set his blessed phiz in ‘a picture of silver;’ the operation took two minutes and a half, and Mr. G. handed him a miniature, perfect in all respects, drawn by the Daguerreotype art true to nature.  All bachelors, at least, should visit Mr. G., and those not entirely deprive posterity of a little image of their noble selves.  His room, No. 18 Franklin Building, where numerous specimens of his skill may be seen.

Theodatus Garlick is recorded in Craig’s Daguerreian Registry and Ohio Photographers 1839-1900 as being active in Cleveland, Ohio from 1839-1841. Also recorded in The New York Historical Society’s Dictionary of Artist’s in America 1584-1860. As a Sculptor and wax portraitist.  Garlick is a work in progress and only a cursory search has been done of the Cleveland newspapers.
