A letter of Dr. John Wallis to Robert Boyle Esq; concerning the said doctor's essay of teaching a person dumb and deaf to speak, and to understand a language; together with the success thereof: which letter though written many years since, was but lately obtain'd to be inserted here, it being esteemed very well worth to be preserv'd and communicated for publick use
