Event Comment: Portia by Mrs Siddons being her first appearance upon this Stage a good figure rather handsome--wants Spirit and ease her Voice a little course very well receiv'd (Hopkins, Diary). Paid Mr Wrighten on note #100; Mr Garrick 2 nights for Bon Ton and Little Gipsey, #238. Receipts: #197 (Treasurer's Book). Books of the Songs and Chorusses of the Afterpiece to be had at the Theatre. [This note appeared on all subsequent bills advertising the Jubilee this season.] The most accomplished actress can display little other abilities in this part [Portia] than a correct elocution, and a knowledge of the author. The lady of last night being thus circumstanced [her first appearance] it is impossible to pronounce what the nature or extent of her powers may enable her to execute when placed in a situation that calls them forth. But from the speciman she gave there is not room to expect anything beyond mediocrity. Her figure and face, although agreeable, have nothing striking, her voice (that requisite of all public speakers) is far from being favourable to her progress as an actress. It is feared she possess a monotone not to be got rid of; there is also vulgarity in her tones, ill calculated to sustain that line in a theatre she has at first been held forth in; but as these observations are formed when the lady laboured under the disadvantages of a first attempt in the metropolis, her future efforts may perhaps entirely remove them (Middlesex Journal, 30 Dec. Quoted in Hampden, Journal)

Event Comment: Mainpiece: Not acted these 16 years [not acted since 27 Oct. 1758]. With Alterations [by Richard Brinsley Sheridan. Prologue by David Garrick]. The Characters new dressed. This Play is revived with Alterations (by R. B. Sheridan Esq) and a new occasional Prologue written by Mr Garrick? and spoken by Dodd, both well received. Miss Essex made her first Appearance upon this stage in Silvia, a small mean Figure and shocking Actress, so bad that she is to do the Part no more. Reddish was very imperfect in Vainlove from the Beginning, but was so very much so in the last Act, that the Audience hissed very much, and cryed out, 'Off, Reddish, Off!" He went forward, and addressed them as follows, 'Ladies and Gentlemen, I have been honoured with your Favour and Protection for these ten years past, and I am very sorry to give any cause for your Displeasure now; but having undertaken the Part at a very short Warning, in order to strengthen the Bill, and having had but two Rehearsals for it, puts it out of my Power to do Justice to the Part, or myself.' The Play then went on. So great a Lye was never delivered to an Audience by any Actor or Actress before. He had the Part at least six weeks in his Possession, and repeated Notice to be ready in it, and six Rehearsals was called for it,--indeed, he attended but three. Vernon undertook to study the Part at eleven o'clock to-night, and to perform it to-morrow (Hopkins Diary). [Miss Essex was from the hay.] Receipts: #209 6s
