Unidad documental simple 17 - Letter from James Joseph Sylvester to Arthur Cayley

'As Savilian Prof[esso]r of Geometry I think it desirable to appear from time to time as a worker on Geometry so as to make up for my deficiencies in the eyes of the University in other parts of my duties as Professor'; intends to write a short article for the Philosophical Magazine on Magnus' theorem and asks Cayley to refer him to Magnus' original paper; 'I can apply my equations to obtain the motion required to bring the two schemes onto perspective relation very simply - ie I can get what you call the kinetic matrix'. Further discussion of this, in relation to Cayley's work.
