... ordering their half pint of rum to be daily mixed with a quart of water, which they that are good husbands may from the savings of their salt provisions and bread purchase sugar and limes to make more palatable to them ("... eis tertiaria rhomii cum congio aquae misceri mandans, quibus ii, ut sibi accommodent, si sapientes oeconomi sint, e salariis panaticisque parsis saccharum et lumias emere poterunt").[2]
Ille ergo primus, quorum scimus, mixturam aquae vitae et suci fructuum, sicut in potionibus amaris adhibetur, praecepit. Nomen huius potionis mixtae ex agnomine inventoris demitur, qui e cucullo grogram a se induto Grog a nautibus nuncupabatur. Quam rem inter primos medicus classiarius, qui et poëta, Thomas Trotter versibus anno 1781 scriptis commemorat:
A mighty bowl on deck he drew,
And filled it to the brink;
Such drank the Burford’s gallant crew,
And such the gods shall drink.
The sacred robe which Vernon wore
Was drenchèd within the same;
And hence his virtues guard our shore,
And Grog derives its name
("craterem potentem in pontem ponens ad labrum replevit, e quo nautae Burford biberunt. Talem potum dei bibent. Mitra sacra quam induebat inde tincta est. Virtus eius oram nostram protegit: exinde potio grog nominatur").[3]
