    ON •> THE DUHATION OE PEEGNA.^CY, AND THE CALCULATION OF THE DATE OF CONFINEMENT. IS DK WM. HAEVEY OE I»B WM. MONTGOMERY IN THE EIGHT ? By J. MATTHEWS DUNCAN, M.D., F.K.C.P.E., LECTURER ON MIDWIFERY, ETC. / - [reprinted from the EDINBURGH MEDICAL JOURNAL, NOVEMBER 1856.] On January 13, 1854, I read before the Royal Medical Socitey a paper entitled Reflections on the Duration of Pregnancy, with Remarks on the Calculation of the Date of Confinement.”^ I there shelved, inter alia, 1. That the interval between conception and parturition (the real duration of pregnancy) has not been exactly ascertained in any case. 2. That the average interval between insemination and parturh tion (commonly called the duration of pregnancy) is 275 days. 3. That the average interval between the end of menstruation and parturition is 278 days. In the British and Foreign Medico-Chirurgical Review, for July 1854, there appeared an abstract of a paper, by Dr Gustav Veit, Professor of Midwifery at Rostock, on the duration of pregnancy and other subjects. I have had no opportunity of seeing more of this essay than is contained in the midwifery report of the above journal. Dr Veit has tabulated forty-five cases from Reid, Mont¬ gomery, Girdwood, Rigby, Lockwood, Lee, Desormeaux, Dewees, ^ See Monthly Journal of Medical S<yience, March 1854.
