Millikan's paper is a 12 page abridgement "of a paper presented on April 23, 1910, before the American Physical Society," and published here (Science, Issue XXXII, No. 822, September 30, 1910, pp 436-448) by request of the editor. This report discusses the first use of oil drops (popularly known as Millikan's oil drop experiments) to measure the charge of an electron. Previous experiments published in the Philosophical Transactions (1910) used water droplets. The un-abridged article was published over six months later in April 1911 in the Physical Review.
Ezhela terms this work the 'First conclusive measurement of the charge of the electron'. Robert Millikan was awarded the 1923 Nobel Prize in Physics 'for his work on the elementary charge of electricity and on the photo-electric effect.'
