[CK621-F] Research Notebook (1901-1903)

This bound volume contains experimental notes and test results by Robert Rafn. The book covers the period March 1901-May 1903, but one of the loose items found in the book dates from 1900. The entries deal with a variety of competing storage batteries, including the Jungner battery; a motor and speed controller for electric vehicles; and an electric meter. A blueprint of a "Chloride Accumulator" has been pasted into the back flyleaf. The first page has been used as a table of contents. The cover is stamped "Record." The book contains 197 numbered pages; many pages are blank.

All entries in the book, including the blueprint, have been selected. Of the numerous loose pages, only the two dated items have been selected.
