Note The compressed Guncotton contg about 18% moisture proved to be so successful that it was adopted by several countries (especially by Russia) for loading not only of sea mines but also of Whitehead torpedoes and cannon shells. Russian Artillery used it during the Russo-Japanese War (1904—1905), but it proved to be inferior to Japanese shells loaded with Shimose (cast Picric Acid). Senior author of this Encycl, who served in 1917 in the Russian Navy, remembers that torpedoes on his destroyer of 1905 vintage were loaded with compressed, moist Guncotton... 

Picric Acid (PA) (Pikurinsan). See Oshokuyaku (Army) and Shimose Bakuyaku (Navy)... 

To the above discussion may be added that the Russians used compressed Guncotton, contg ca 17% of moisture since about the 1860 s for loading ammunition but during the Russo-Japanese War (1904-1905), Russian shells loaded with Guncotton proved to be much inferior to Japanese shells loaded with Shimose (cast Picric Acid). Some Whitehead torpedoes of the Russian Navy were loaded with Guncotton as late as WWI. One of the older P.ussian expls, known as Slonit (Elephantit) consisted of Guncotton hydraulically compressed to the hardness of elephant s bone... 

Shimose or Shimoza. Japanese term for Picric Acid, named in honor of Captain I. Shimose, who developed a method for casting PA into shells at the beginning of the century. These shells were successfully used during the Russo-Japanese War, at which time the Russian shells contained pressed NC contg about 18% moisture. Also see Picric Acid in Vol 8, P285-R to P295-L... 

Picric Acid (melinite, lyddite, pertite, shimose, etc.)... 

When used as a shell filling in British service, Picric acid was known as lyddite, after Lydd in Kent, where it was first tested. In other countries, it was variously called melinite, shimose, pertite and picrinite.
