Charlotte was to go, with excellent health, to bathe and be better if she could
This draws parallels to Fanny Price from Mansfield Park, who was also sent to a new location in order to undergo character development and most importantly find someone on the marriage market.
They were anti-spasmodic, anti-pulmonary, anti-septic, anti-billious and anti-rheumatic. Nobody could catch cold by the sea; nobody wanted appetite by the sea; nobody wanted spirits; nobody wanted strength.
An example of free indirect discourse that taps into the perspective of Mr Parker. Free indirect discoures is a technique Austen frequently graces her audience where she uses third-person narration to portray the perspective of a character and their consciousness as they perceive the world.
generally
in her novels, Austen often uses moderate modality words that add a tone of speculation to her description. This addition of "generally" is similar to how Emma "seemed to unite some of the best blessings of existence" that encourages her audience to sense a disconnect between the general appearence and the exceptions.
succeeding as eldest son
In Austen's novels, birth order is an important aspect of one's identity, particularly in consideration of their expected fortune. One of the main issues a character who is not the eldest face is not being an inheritor of the fortune, which then affect their marriage prospect of freedom of choice. An example of such is Colonel Fitzwilliam in Pride and Prejudice, who is the youngest son of an earl without expectations of much inheritance and thus has to use marriage also to ensure his own financial security. This is also the case for Edmund in Mansfield Park who becomes a clergy to support himself.
Heywoods were a thoroughly respectable family
Similar to all the other families that Austen's characters happen to interact with - all "respectable" families of probably the gentry class. In Pride and Prejudice, the Bingleys were "of a respectable family in the north of England" (P12) while in Northanger Abbey, Mr Tilney was also "of a very respectable family in Gloucestshire" (p17).
they were glad to promote their getting out into the world as much as possible
The Heywoods contrast Mr Woodhouse in Emma who was extremely cautious over his daugher and other young people being in the world.
they were very accomplished and very ignorant
Austen uses an apparent paradox to comment on the failure of accomplishments as the suitable form of education for young women, through the ironic characters that have equally all the considered accomplishments of the world and all the lack of proper understanding like Miss Bingley in Pride and Prejudice.
two and twenty
An appropriate age for most of Austen's heroins on the marriage market e.g. Emma is 21, Elizabeth is 20, Jane 22, Elinor 19
