Howlite

Howlite was discovered near Windsor, Nova Scotia in 1868 by Henry How (1828–1879), a Canadian chemist, geologist, and mineralogist.

How was alerted to the unknown mineral by miners in a gypsum quarry, who found it to be a nuisance. He called the new mineral silico-boro-calcite. Shortly after it was given the name Howlite by James Dwight Dana (1813–1895) who was an American geologist, mineralogist, volcanologist and zoologist.

Howlite is to be extremely calming stone and said if placed under the pillow it is an excellent antidote to insomnia, especially when this is caused by an overactive mind. It is also said to balance the calcium levels within the body and aids teeth, bones, and soft tissue.
