This conventionalized bird is a fragment from his decoration for the chest in which he kept his "scientific work" at that time. This oblong chest he painted Chinese red, with three figures on the front. These were the conventionalized bird here shown, a conventionalized nest with eggs, and a conventionalized butterfly-- all painted in striking combinations of yellow, blue, green, and red. D loves color, and one of his favorite playthings has been a sample folder of silk buttonhole twists of three hundred shades. Between the ages of 8 and 9 years he would go over and over these, classifying the colors in various ways, scoring them for beauty, and renaming them to satisfy his appreciation of them. Some of these names will give an idea of his appreciation: spotted pale dark darking green darkling green regular green shame blue paper white spoiled pink apron blue soft light pink beau yellow meadow beauty pink visitor's green cat black alien white royalest red feeling blue One of his favorite games (aged 8 to 9 years) was to assign a numerical value to each of the 300 shades and then to list them for "highest honors." "Royalest red" nearly always won in these contests. _Origination of new concepts and new words_. From earliest childhood D has felt a need for concepts and for words to express them that are not to be found in dictionaries. His occupation in this field he calls "wordical work." Some examples are recorded by his mother in the following note dated December, 1916. Was having his dinner and being nearly finished said he didn't care to eat any more, as he had a pain in his actum pelopthis. He explained that his actum pelopthis, actum quotatus, serbalopsis, and boobalicta are parts of the body where you sometimes have queer feelings; they don't serve any purpose. He said he also had a place called the boobalunksis, or source of headaches; that the hair usually springs out from around the herkadone; that the perpalensis is the place where socks end, and the bogalegus is the place where legs and tummy come together. He also named one other part, the cobaliscus or smerbalooble, whose function is not explained. The definitions are exactly as he gave them in each instance. On February 23, 1917, his mother wrote: He has not referred to these places since. I do not know where he got the idea for such names, unless possibly from _The Water Babies_. He would probably refer them to some Bornish source. The invention and classification of the Bornish language already referred to is another example of D's "wordical work." He has also invented hundreds of words which have not been included as Bornish. An example of his hand-writing, illustrative of words he has invented, classified, and recorded for pleasure, is here shown. FIG 6. ONE OF D'S VERBAL INVENTIONS.
