Llawysgrif yn dwyn y teitl 'Traethawd ar Ddylanwad y Meddwl ar Weithrediadau y Corph' a gyflwynwyd dan y ffugenw 'Myfyr' yn Eisteddfod Annibynwyr Ffestiniog Nadolig 1883. = A manuscript essay entitled 'Traethawd ar Ddylanwad y Meddwl ar Weithrediadau y Corph' submitted under the pseudonym 'Myfyr' for competition at the Congregational Eisteddfod at Ffestiniog, Christmas 1883.
Rhennir y traethawd yn un bennod ar ddeg (ff. 2-65) a cheir ynddi gyfeiriadau at ffigurau nodedig, gan gynnwys athronwyr o'r oes Glasurol hyd y bedwaredd ganrif ar bymtheg; mae yna restr cynnwys ar f. 1. Gwyddys i dri ymgeisydd roi cynnig ar y gystadleuaeth ac i John Jones, Meirion House, Tanygrisiau, ennill y wobr (gw. Y Dydd, 4 Ionawr 1884, t. 7), ond methwyd darganfod ai ef oedd 'Myfyr'. = The essay consists of eleven chapters (ff. 2-65) and contains references to notable figures including philosophers from the Classical period to the nineteenth century; a list of contents is on f. 1. It is known that three entrants attempted the essay and that the prize was won by John Jones, Meirion House, Tanygrisiau (see Y Dydd, 4 January 1884, p. 7), but it has not been possible to ascertain if he was 'Myfyr'.

Giffard received the book as a gift from John Stead (f. 78 verso), admitted to the same college as fellow-commoner 1598-9 (see Alumni Cantabrigienses).
The main subjects of study are the tragedies of Seneca (ff. 6-54 verso). A few medical notes are included (ff. 1-2).
