On a Case of nervous Affection cured by Pressure of the Carotids; with some physiological Remarks. By C. H. Parry, M.D. F.R.S. page 390 On the Non-existence of Sugar in the Blood of Persons labouring under Diabetes Mellitus. In a Letter to Alexander Marcet, M.D. F.R.S. from William Hyde Wollaston, M.D. Sec. R.S. Reply of Dr. Marcet on the same subject

On the Rectification of the Hyperbola by Means of Two Ellipses; proving that Method to be circuitous, and such as requires much more Calculation than is requisite by an appropriate Theorem: in which Process a new Theorem for the Rectification of that Curve is discovered. To which are added some further Observations on the Rectification of the Hyperbola: among which the great Advantage of descending Series over ascending Series, in many cases, is clearly shown; and several Methods are given for computing the constant Quantity by which those Series differ from each other.
