Martindale Poor Man’s Inhaler London

This is a very rare inhaler. William Martindale opened his first shop in London from 1883 and became president of the pharmaceutical society between 1899 to 1900. He died in 1902. This jar is the first example I have seen. Height 4.5 inches, width 4 inches. Likely had a cork top which is missing. Glass tube included. C1885/1900
