He published devotional verses, 1671, a treatise on shorthand, 1674, primers of English and Latin, 1674-5, an English dictionary, 1676, and a Latin dictionary, 1677.[1] The shorthand used by Thomas Bayes has been identified as that of Thomas Shelton, as modified by Coles.[3]
His 1676 Dictionary contains
"many words and phrases that belong to our English Dialects in our several Counties, and where the particular Shire is not exprest, the distinction (according to the use) is more general into North and South-Country words."
Coles' dialectal entries are mostly collected from the glossary by John Ray with some additions from the Dictionarium Rusticum in John Worlidge's 1669 Systema Agriculturae.
