whilst pretty to see the Waiters dance Attendance with the Refreshments, and hear the hollaing and shouting, and altogether a good Deal of Fun, but dreary; but a Family of little Boys and Girls with their fat Father mighty merry, and clap their Hands to see the Balloon go up in another Part of the Gardens. A grand Display of Fireworks to conclude diverted me too, and so Home and to Bed, hoping after my Evening's Entertainment I shall not wake with a Headache in the Morning. [Illustration: _A SCIENTIFIC INSTITUTION._ FRIDAY (_further date wanting in MS._). WEEKLY EVENING MEETING.] This Evening to the Royal Institution, to hear Professor OWEN, the Hunterian Professor to Surgeons' College, Lecturer on Comparative Anatomy and Physiology, on the Nature of Limbs. To the Institution early, to the Theatre, and there got a good Place, the Theatre already filling and soon crammed like any Playhouse where some leading Actor make his appearance in a great Part, Gallery and all, as they say, to the Ceiling.
