London, December 9 : Letters of a 19th century scientist that are believed to have inspired Mary Shelley’s immensely popular novel ‘Frankenstein’ have been made available for public view.

The two memos penned by Andrew Cross, an early pioneer and experimenter in the use of electricity, held details of his tests that included attracting lightening to strike a network of copper cables during electrical storms.

The scientist had become widely known after press reporting of an 1836 electrocrystallization experiment in which the Brit believed he saw creation of new life or "some products formed in a new manner".

Cross is said to have known Shelley through a common friend, poet Robert Southey.
