An abstract of Thorsten Nordenfelt'd lecture on the Nordenfelt submarine read at the United Service Institution on the 5th of February 1886. In which Nordenfelt maintained that previous submarines had failed - (1) because they were small and weak; (2) they tried to act by actual contact with the enemy's ship's bottom, which was very dangerous and difficult, especially if the ship was pitching at all; (3) black powder was used, which is an unsuitable explosive for the work; (4) propulsion was effected by hand power, which taxed the crew too severely; (5) the means of ascending and descending were untrustworthy.
