In 1864 How published the description of a new zeolite mineral, that he named mordenite, from along the shores of the Bay of Fundy. In 1868, he described a new borate mineral found just south of Windsor. How named it silicoborocalcite but was renamed howlite in his honor by James Dwight Dana. He studied many other zeolites and related minerals from the Bay of Fundy basalts, borates from the gypsum and anhydrite deposits, as well as ores of manganese and iron.

Personal life

How married Louisa Mary Watkins (11 May 1830 - 9 July 1910) and they had five children. The grave of one of their children is next to Henry How's and reads, Louisa P. Juliet, second child of Henry How and Louisa M. How, died 8 July 1862 aged 4 years and 6 months.
