*hiuret (thi'-u-ret) [dtiov, sulphur], C 8 H.X 3 S 2 . An 

 antiseptic which readily yields its sulphur in a nascent 

 condition. On this property depends its antiseptic ac- 

 tion. It is a crystalline powder, practically insoluble 

 in water, and is best used in combination as the borate, 

 or perhaps best as the parasulphophenate. 

 hlipsencephalon (thlip-sen-sef -al-on). See Thlip- 



ilns. 

 hlipsencephalus (thlip-sen-sef '-a/us) [d/uibtc, pres- 

 sure ; i; . <HW.'/r>r , brain]. A variety of single autositic 

 monsters of the species pseudencephalus, in which 

 there is extensive exposure of the base of the skull 

 from non-development of the occipital bone and even 

 of the upper vertebras.

 especially of blood-vessels. 



aoka-Losi (tho-kah-lo'-se). An Australian and Fijian 

 form of mutilation, consisting in the incision of the 

 urethra at the membranous portion. The object is 

 supposed to be a superstitious method of treating 

 rheumatism and sundry fevers. Another similar 

 method of mutilation for supposed similar reasons is 

 called Targangalengale, incision of the urethra 

 from the meatus to the frenum. Similar mutilations 

 ire practised by some of the Arabs and by certain 

 African tribes.

'iomsen's Disease. Myotonia congenita; a dis- 

 commonly congenital and occurring in families, 

 md characterized by tonic spasm or rigidity of the 

 nuscles, coming on when they are first put in action 

 Iter a period of rest. As the muscles are used the 

 .ess gradually wears off. The disease usually 

 ppears first in childhood at about the age of eight or 

 years. The etiology is obscure ; the duration 

 Indefinite. No treatment is of any avail. The Jfyo- 

 Reaction is characterized as follows : The con- 

 faction of the muscles upon mechanical stimulation of 

 ae motor nerves is normal. Mechanical stimulation 

 t the muscles easily induces contraction lasting 

 om five to thirty seconds. The galvanic current ap- 

 lied to the muscle shows that opening contractions 

 re very difficult to obtain, that the closing contrac- 

 ons are of very long duration, and that upon stabile 

 [.plication well-formed, wave-like contractions may be 

 :en to pass from the kathode to the anode. The re- 

 jxes are normal. See Diseases, Table of.
