This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

John Adolph Dahlgren was the son of the Swedish consul at Philadelphia, Pennsylvania, and was born in that rity on November 13, 1809.
Dahlgren entered the American Navy in 1826 and in 1847 became ordnance officer at the Washington Navy Yard, where he established a full-fledged ordnance department and began manufacturing cannon of his new type. His cannon were first mounted in an experimental vessel that cruised (1857–59) under his command. They were "the first practical application of results obtained by experimental determinations of pressure at different points along the bore, by Colonel Bomford's tests that is by boring holes in the walls of the gun, through which the pressure acts upon other bodies, such as pistol balls, pistons.
When the Civil War broke out, he was one of three officers in the Washington Navy Yard who did not resign because of Confederate sympathies. Promoted to captain, he saw active sea duty and in 1863 became a rear admiral. He was in command of the Washington Navy Yard at the time of his death.

Admiral Dahlgren had three sons from his first marriage to Mary Bunker (1839). Admiral Dahlgren's eldest son, Charles Bunker Dahlgren, was an engineer and captain in the Union Navy. After his father's death, he would write and present many technical papers on military weaponry, including the Dahlgren gun. Ulric Dahlgren (1842-1864) was a soldier in the Union Army and was killed in an unsuccessful mission to liberate Federal prisoners in Libby Prison and Belle Isle. Another son, Paul Dahlgren, also in the army, died in 1876 while serving as consul general in Rome.
In 1865, Dahlgren married his second wife, Sarah Madeleine Vinton, daughter of Congressman Samuel Finley Vinton and Romaine Madeleine Bureau, and the widow of Daniel Convers Goddard, first Assistant Secretary of the newly created U. S. Department of the Interior.
Their children were John Vinton Dahlgren, who married Elizabeth Wharton Drexel; Eric Bernard Dahlgren, Sr. , who married Lucy Wharton Drexel; and Ulrica Dahlgren, who married Josiah Pierce, and was the grandmother of Romaine Dahlgren Pierce, wife of David Mountbatten, 3rd Marquess of Milford Haven.
