An Invention Jbr toriting hy means 

 of Copies engraved on Slates. 

 ^From Transactions of the Socie- 

 ty for the Encouragement oj Arts, 

 ManuJactureSf and Commerce. 

 Vol. xxvii.] 



f The silver medal of the Society 

 forthe Encouragement of Arts, &c. 

 and ten guineas, were this session 

 voted to Mr. Thomas Warren, jun. 

 for his invention of teaching to 

 write on a cheap plan, by means of 

 copies engraved on slates.] 

 Sir; 



I BEG leave to offer some engraved 

 elates of my itivention, to the in- 



spection of the society for the en- 

 couragemeat of arts, manufactures, 

 and commerce, humbly submitting 

 to their consideration, whether 

 they may be deemed worthy of re- 

 ward. 



The great utility of this article 

 in instructing the children of the 

 poor, particularly in the art of 

 writing, has been amply proved in 

 several respectable charity-schools, 

 at Bury St. Edmunds, also in many 

 private families for the last nine 

 months. 



This invention occasions great 

 saving in writing-paper, pens, ink, 

 and labour in teaching. 



In making use of these slates, 

 the slate pencil is recommended to 

 be placed in a quill, and to be 

 held exactly after the manner of a 

 pen, by which means the hand is 

 made pliant, preparatory to the 

 use of tiiat instrument on paper. 



Small slates without capitals, 

 which are the sort recommended to 

 schools in general, are sold for fif- 

 teen shillings the dozen, by one of 

 which all the children in a family 

 may learn to write, and with care 

 it will last for ages. Small slates, 

 with capital letters, are sold at one 

 guinea the dozen. They may be 

 procured onmyaccount fromMessrs. 

 Chanipante and Whitrow, station- 

 ers, Jewry-street, Aldgate ; and 

 Messrs. W. and C. Child, Lower- 

 Thames-street. 



The method I recommend in 

 making use of my small slate, with 

 the two addition sums engraved 

 upon it, is to cut off with the pen- 

 cil the three lower lines for the first 

 sum, then four lines, then five, 

 &c. by which means the two sums 

 answer the purpose of many; I 

 have proved this slate to be of 

 great use in schoolis. The large 



slate,
