Where to find further information on functional equations. Gives further equations for JH's comments. Regarding the proposed abridgement of J. B. Delambre's work on astronomy.
Where to find further information on functional equations. Gives further equations for JH's comments. Regarding the proposed abridgement of J. B. Delambre's work on astronomy.
Regarding his new researches into the theory of determining functions from given conditions. The printing of his memoir is proceeding slowly.
Has been to London and procured the books mentioned by CB. Mentions differential equations of P. S. Laplace. Regarding some of CB's theorems. Problem of law of chance. Printing of his memoir.
Sends a number of theorems and integrals.
Will be visiting London shortly and hopes to purchase some experimental equipment to carry out experiments with heat.
Orders equipment from London through CB.
Would like to see him as soon as possible so they can prepare the preface of their memoir for the printer.
Has had the bill for the printing of their memoir. Ways of raising money to pay for the printing. Comments on one of CB's equations. Will be entering Lincoln's Inn in a week's time.
Regarding the proposed method of raising funds to pay for printing of the memoir. Justifies his equation queried by JH. Would he purchase certain chemicals for him.
Chemical news: decomposition of 'sulphuret of carbon' by J. J. Berzelius and Alexander Marcet. Analysis of 'azotane' and discovery of 'iode' by Humphry Davy. Congratulations on results of CB's examination.
Is sending chemicals. Regarding Humphry Davy's experiments with azotane. Davy's paper on iodine.
Will be in town and requests addresses of shops where certain experimental apparatus can be purchased. Send [H. E.?] Roscoe's direction.
Has been working on analysis. Gives equations he has solved. Has met a mineralogist.
Their 'Analytical' has not been reviewed in the Edinburgh Review. Has married. Looking out for a situation. Gives an equation dealing with relative functions.
Sends equations in operational calculus.
Feigned reproach for CB's return to 'the Analytics.' Inquires about CB's 'Devonshire Ghost at Chudleigh.' Results of JH's chemistry experiments. Derides scientists who promote theory of 'akasch' as the one and only form of matter. Met Alexander Marcet in Greenwich.
Comments on the equation sent by CB. Has been experimenting with potassium.
Regarding CB's marriage. Possibility of a suitable situation for him.
Temper and stinginess of CB's father. Seeking job in mining through Mr. Champernowne, local mineralogist. Describes CB's elopement, marriage by former tutor, and new residence. Considered career in Church when CB had prospect of inheriting fortune from CB's father, but that is no longer possible. Gives an equation for discussion.
Gratitude for CB's friendship. Chemical supplies and instruments. Describes synthesis of 'Sulphurane' [S2Cl2] and other experiments. Theories of combustion and acids. [Letter continued on 1813-9-21:] JH avidly studying law, against father's wishes.
