Sixth edition printed in 1837. The type of the ToC has been reset, but the content appears to be identical to the Schultz Archive's 1832 printing. The author is not credited on the title page. C. Mayo signs the preface, in which he credits his sister for “the execution of the details” resulting in “the Exercises, now for the first time presented to the public.” Grade school education through the Pestalozzian method of question/answer dialogue and expanded analysis on common objects. The works consists of five series of lessons of increasing difficulty. The objects in the first series are chosen for having a distinguishing quality and for each having some obvious connection to what has preceded them. Objects in the first series include leather, water, bread, whalebone, rice, and chalk. Items in the second series include a pen, a chair, and a key. Items in the third series include a quill, a piece of honey-comb, an oyster, and a needle. Items in the fourth series are in two categories: spices and liquids. Items in the fifth series include a mixture of previously covered objects and new ones as well as the categories of metals, earths, and the senses. The descriptions evolve from lists of parts and qualities to long paragraphs. The Schultz Archive's copy has only a few pages of the text.
