conjoined with other characters, characterize his dif- 
ferent breeds. But here, as in botany, a regular sys- 
tematic Nomenclature of Colour is much wanted. 
* The anatomist will find it much to his advantage, 
to use in his descriptions some regular and fixed stand- 
ard of colours ; and in Morbid Anatomy, in particu- 
lar, the importance of such an aid will be immediately 
perceived: Thus, the various changes in the animal 
system, from the slightest degree of inflammation to 
complete gangrene, are strikingly marked by the dif. 
ferent colours the parts assume. ~Accurate enumera- 
tions of these colours as they occur in single varieties, 
or in groups, conjoined with descriptions of the changes 
in form, transparency, lustre, consistency, hardness, 
structure, and weight, observable in the diseased parts, 
will convey an accurate conception of the diseased 
parts to those who have not an opportunity of seeing 
it. But to effect this, the anatomist and surgeon must 
agree on some fixed nomenclature, not only of colour, 
but also of form, transparency, lustre, consistency, 
hardness, and structure ; and a better model cannot 
be pointed out than that contrived by Werner, for the 
description and discrimination of minerals.
