Beatrice the Sixteenth: Being the Personal Narrative of Mary Hatherley, M.B., Explorer and Geographer is a 1909 feminist utopian novel by the English lawyer, writer, and activist Irene Clyde.

The inhabitants of Armeria live in a harmonious environment, emphasising equality and mutual respect, without the strict gender distinctions present in Mary's world.

The people of Armeria engage in intellectual pursuits, artistic expressions, and a communal way of life that prioritises collective well-being over individual ambition.

Mary witnesses the bravery and sacrifice of the Armerians, particularly through the actions of Ilex and other key figures who embody the spirit of their society.

The Armerians' defence of their homeland is portrayed with both grandeur and intimacy, focusing on individual stories of bravery and the collective determination to preserve their society.

Mary, now fully a part of Armerian society, forms a conjux with Ilex and contemplates the lessons she has learnt and the transformative power of their example.

The manuscript concludes with a note revealing that Mary has decided to stay in Armeria, entrusting her story to be shared with the world to inspire others to envision a society founded on equality and respect.

[7] Sonja Tiernan argues that the book is critical of heterosexual marriage and presents it as only being redeemable when it's based on a relationship between people of the same gender.

[10] Louise Radford Wells found the novel unusual and was initially confused by the characters' genders, later realising that each heroine was also a hero.

Hierarchical and binary distinctions are the foundational poles of this alternative existence—Armeria/Uras, free people/slaves, civilised/barbarians—whilst in its practices of "conjux" (which means "a joined person") the Western conventions of monogamy and marriage are upheld.Matt Polzin argues that in Clyde's vision of an ideal future society, which is achieved by abolishing gender, she relied on other classification systems, including colonial hierarchies.

[14] Lucy Ella Rose claims that Clyde's uncritical approach to enslavement reveals her work's elitist and hierarchical tendencies.

These aspects align Clyde's work with other white middle-class feminist writings of the interwar period, situating it within broader literary and scientific modernism debates.
