Ili this same year we find anotlier paper by him, On 
Wood for Shipbuilding.” 
In 1863 he patented and worked at his process for the 
separation of sulphur from coke, by use of common salt, for 
the purpose of the manufacture of iron of superior quality. 
The following is a list of some of his further publications : 
In I860 “On the Action of Silicate and Carbonate of 
Soda upon Cotton Fibres.”— “ On the Crystallized Hydrate 
of Phenic Alcohol.” 
In 1866 “On the Hydraulicity of Magnesian Limestone.” 
“ On the Preparation of Acetylene.” 
About this time he interested himself with the properties 
of phenic or carbolic acid, and being satisfied of its valuable 
disinfecting properties, built works for its manufacture, 
and to him belongs the honour of having first brought it in 
a pure state into commerce. 
In 1867 he wrote papers “On Oxidation by means of 
Charcoal.”— “ On the Presence of Soluble Phosphates in 
Cotton Fibres, Wheat, and other Seeds,” and five articles 
“ On the Synthesis of Organic Substances.” 
In 1867 “Carbolic or Phenic Acid and its Properties” 
(three articles). 
In 1869 “Presence of Soluble Phosphates in Seeds.”— 
“ Preparation of Nitrogen.” 
In 1870 “Testing Petroleum.” 
In 1872 “Sulphur in Coal and Coke;” and papers on 
“Protoplasmic Life;” “Vitality of Disease Germs,” &c. Part 
of the latter series remains yet unpublished. 
In concluding the list of Dr, Crace-Cal vert’s various 
researches we may mention that, besides the above, many 
others were made by him, but their unfinished state does 
not justify publication. Among these may be mentioned 
one on “Light,” which cost him much labour, and one 
“On the Action of different Gases on each other under 
Enormous Pressures.”
