2. Blue and red (or scarlet) and white and purple and yellow, or 



rather gold or orange harmonise well. (See PI. in. fig. 1 1 ; and 

 A 7; B7.) 



3. Blue and red (or scarlet) and green and yellow (or gold) on a 



white ground harmonise. 



4. Blue and red (or scarlet) and yellow (or gold) and brown and 



white harmonise. 



5. Blue and red (or scarlet) and yellow (or orange or gold) and purple 



and black harmonise well. (See PI. iv. fig. 2.) 



6. Blue and red (or scarlet) and orange and chesnut and white har- 



monise. 



7. Blue and red (or scarlet) and yellow (or rather gold or orange) 



and black and white harmonise, and are better than the three 

 primaries alone, but they could be improved still farther by a 

 little green. (See p. Ill, and PI. iv. fig. 5.) 



8. Blue and scarlet (or red) and a little green and yellow and black 



harmonise, but wanting. This was also an Egyptian combi- 

 nation. 



9. Blue and orange and green and black and white (or on a white 



ground) harmonise, and have an agreeable effect, as in some 

 of the tiles at the Alhambra. This also shows that combina-

 harmonious combination — blue and orange. (See PI. in. figs. 

 1, 12.)

14. Blue and orange and black and purple and white (or on a white 



ground) wanting. (See D 10 ; E 3, 5, 8 ; F 1, 3, 4, 6, 8.) 



15. Blue and orange and brown and yellow and white wanting. 



16. Blue and orange and brown and yellow and purple wanting. 



17. Blue and crimson and yellow and green and white unsatisfactory. 



It would be better without green, with scarlet instead of 

 crimson, and wants black. 



18. Blue and yellow and green and purple and brown discord. 



19. Blue and yellow and green and purple and white disagreeable. 



20. Blue and green and purple and white and orange wanting, and 



depending much on the proportions and arrangement of the
