So much I write at present, most learned sir, trusting it will be taken in good part as coming from yours,

Very sincerely and respectfully,

Most noble Harvey, I only wish you could snatch the leisure to ex- plain to the world the true use of these lymphatic and thoracic ducts. You have many illustrious scholars, particularly Highmore, with whose assistance it were each to solve all doubts." ED.]
