first, not abated, column, all those of the second, once abated range, end 

 with 2 or 7, all those of the 5th, 4 times abated range, end with" 5 or 0. 



The hundred first numbers contain all derivations of red, gradually 

 more mixed with orange, unto orange, the second hundred those of yellow, 

 the third century all blue etc. Thus 213 is the second abatement of a 

 dilution of yellow 201, and because 206 is the first dilution, and 211 the 

 second dilution 213 is the second abatement of the second dilution of yellow. 



In this series the much diluted tinges are scantiy represented. Therefore 

 another 120 numbers, 5 on each page, are added indicating the very bright 

 tinges, the first of which, on the first column, is derived from the normal 

 colour and has the same cipher as the most diluted one of that column, 

 augmented With a zero, so the 4th dilution of red is 5, the fifth is 05, 

 the. 4 that follow are dilutions of the second abatement of that colour, 

 their gradations indicated by the letters A. B. C. D. Thus 3 D is a dilution 

 of the second abatement of red. 



For those of my readers to whom this booklet is not available 1 give 

 here a survey of the numbers and names used in the "Chromotaxia" of 

 Saccardo, comparing them with some of the most important ciphers, derived 

 from the "Code", used in this treaty. 



I. Red and brown colour. (1 — 100. Code).. The pure red colours,! and 

 26, with their dilutions are wanting in Saccardo. They occur however in 

 the fruiting spikes of Zingiber species. 



Ruber, Red, Sacc. 14 is orange-red, Cod. 76, 81, and related tinges. 

 Miniatus, Scarlet, Sacc. 15 is very near to Cod. 68 = twice diluted orangered. 

 Incarnatus, Flesh-colored, Sacc. 16, is about 96 = fourtimes diluted 

 orangered. Ro^eus, Pink, Sacc. 17, is about 21, fourth dilution of pure 

 red, but there are also many dilutions of red violet, which may be named 

 "pink" or "rose-coloured" e.g. 596 and related colours. Testaceus, brick- 

 coloured, Sacc. 18, is about 87 = red-orange once abated, twice diluted; 

 and numerous related colours. Latericius, brick-coloured, Sacc. 19 is the 

 same once more abated = 88. Badius, Bay, Sacc. 20 = 59. Castaneus, 

 chestnut coloured, Sacc. 10, = 54 and 78. 



II. Orange .colours, (101 —200 Code). 



Aurantiaciis, orange-coloured, Sacc. 21=126 and 131. Luteus, egg 

 yellow, Sacc. 22=151. Flavus, yellow, Sacc. 23= 176. Ochroleucus, 

 yellow-whitish, 28=166. Ochraceus, ochre-yellow, Sacc. 29 = 136 and 141. 

 Cremens, cream coloured, Sacc. 27=171 (diluted). Stramineus, Straw 

 colored Sacc. 26 = 0196. Here belong also most tinges of brown : L^mörmus. 

 Umber. Sacc. 9 = 128 and 133. Isabellinus leather coloured, Sacc. 8=127. 

 Avellaneus, drab, Sacc. 7, near 147. Fulvus, Tawny, Sacc. 32 = 112. 

 Ferrugineus, Rusty, Sacc 31 = 107. Mellens, amber coloured, Sacc. 30 = 

 182. Ater, blackish, Sacc. 4=124 Olivaceus, olive green, Sacc. 39= 180.
