Comments Off on Early Tourmanile Tongs for the determination of crystal geometry in optical mineralogy, ca. 1860
Tourmaline is a crystalline boron silicate mineral compounded with elements such as aluminum, iron, magnesium, sodium, lithium, or potassium.

However, the E-ray is rapidly Read More...

Two C1900 Anti-Onanism Devices in Silver

Comments Off on Two C1900 Anti-Onanism Devices in Silver
   ​We are offering  two anti-onanism devices that were certainly less brutal than the​ sharp-toothed​ spermatorrhea ring ​we also have up on Fleaglass. https://www.fleaglass.com/ads/spermatorrhea-ring-used-to-prevent-masturbation-and-nocturnal-emission/  ​These devices are rare but this pair is doubly rare because they were made for children​ or young adolescents​, rather than ​older ​adolescent or adults, and they are solid silver. ​The fact that one of the two is for a female is also notable. There was much less concern in the medical literature of the period about female masturbation, hence relatively few devices were sold to prevent it.Th​e Read More...

The retro-ceps (retro​ behind and capere to seize) of Hamon of La Rochelle (as the derivation of the word implies) ,catches the head at the back, Read More...
