fifty-one years, earning great fame as a successful teacher.
He became, after the tleath of Dr. Thomas Hubbard, the leading surgeon in Connecticut. Especially was he familiar with the literature of surgery. " Consci- entious, forbearing, conservative, per- haps in all that time of his supremacy (which continued until his death), he never did an unnecessary or premature operation" is the tribute paid him by his pupil and successor. Dr. Francis Bacon. He was the first surgeon to cure aneur- ysms by manual compression. This was done in 1848 by relays of assistants from among his pupils at the medical school, who relieved each other at short intervals. After forty hours" treatment, the aneur- 3^sm disappeared.
He was twice president of the American Medical Association, his re-election due to the skillful way in which he presided over its first session, using his common sense, without, as he admitted, much knowledge of parliamentary rules. He died on August 25, 1864. Unfortunately, he wrote little, save two introductory lec- tures and an eulogium on Dr. Nathan Smith. A portrait by Nathaniel Jocelyn was painted in 1828 and is still in existence. \\ . R. S.

Kollock, Cornelius (1824-1897).
Cornelius Kollock, who for the last twenty years of his life devoted himself to gynecology and abdominal surgery in the little village of Cheraw, South Caro- lina, near which he was born in 1824, was well known and consulted in both the Carolinas, and was president of the South Carolina Medical Association in 1887. He was the son of C)liver Hawes and Sarah Wilson Kollock. Student days were passed at Brown University, Rhode Is- land, and his M. D. taken at the Univer- sity of Pennsylvania in 1848, after which he studied in Paris for two years in the leading clinics. Then he settled down in
Cheraw, which village even when he died had only about one thousand persons in it including five doctors, but a glance at the portrait of Kollock shows he knew his own mind and under what circumstances he could do his best work. The "Trans- actions of the American Gynecological Society" show the deep interest he took in professional subjects even when seventy years old.
A Christian man of unflinching integ- rity and courage, skillful in dealing with the diseases and frailties of the little com- munity in which he worked. His death on the sixteenth of August, 1897, caused universal regret.
He married Mary Henrietta Shaw and one son, Charles Wilson, followed his father's profession.

Kreider, Michael Zimmermann (1803- 1S55).
A pioneer surgeon in Ohio, he was liorn in Huntingdon, Pennsylvania, the son of Daniel and Salome Carpenter Kreider, and grandson of Michael and Susan Car- penter Kreider; being thus doubly de- scended from Dr. Henry Carpenter (Zim- mermann), a Swiss physician who located in Germantown in 1698. He attended school in Huntingdon, and acquired, for that day in the West, an unusually good education.
On the death of his mother in 1820 the home was broken up and with a younger brother he walked over the Allegheny Mountains and made his home for two years with an uncle in Delaware County, Ohio, in 1822 beginning to study medicine with Dr. Samuel Parsons in Columbus, and in 1825 after an examination, there being no medical schools in the West at that time, was given a license to practise by the State Medical Board, and settled in Royalton, Ohio. In 1841, having re- tired from political ofhce he took up his practice of surgery with energy and be- came widely known as a surgeon, prob-
