Dr Robinson appears, by his notices contained in the "Philosophical Letters between the late learned Mr Ray and several of his ingenious Correspondents," to have been of considerable use to our author in transmitting information on every subject that seemed interesting to the latter, and especially in procuring objects for description. In one of his communications from Geneva is a passage respecting the celebrated Malpighi, which exhibits the character of that great anatomist in a favourable light:--"I had several conferences with S. Malpighi at Bononia, who expressed a great respect for you, and is not a little proud of the character you give him in your Method. Plantar. Nov., which book I had presented him withal a day before. Just as I left Bononia I had a lamentable spectacle of Malpighi's house all in flames, occasioned by the negligence of his old wife. All his pictures, furniture, books, and manuscripts, were burnt. I saw him in the very heat of the calamity, and methought I never beheld so much Christian patience and philosophy in any man before; for he comforted his wife, and condol'd nothing but the loss of his papers, which are more lamented than the Alexandrian Library, or Bartholine's Bibliothece at Copenhagen." Of the epistolary correspondence of this gentleman, and of Sir Hans Sloane, it may be interesting to some of our readers to peruse a specimen:-- DR ROBINSON TO MR RAY. "London, August 1, --84. "SIR,--I have sent you two _Macreuses_, male and female, and hope they will come safe to Black Notley. My ingenious and worthy friend Mr Charlton (now at London) procur'd them for me at Paris, who hath them both design'd to the life in proper colours by the most accurate hand in France. If you saw the pictures I believe they would give you a better insight than these skins, which are a little broke and chang'd; yet nevertheless your most discerning faculties may discover that in the dark which few can distinguish at noon-day. This Parisian bird (very famous of late) may be no unwelcome subject, it being in Lent, and upon maigre days, the greatest dainty of convents. I have been told by several of the most learned priests beyond sea, that the macreuse was as much a fish as the barnacle (and indeed I am of the same opinion), that the blood was the same in every quality with that of fishes; as also the fat, which (as they falsely affirm) will not fix, dry, or grow hard, but always remains in an oily consistence. Upon these and other reasons the Sorbonists have ranked the macreuse in the class of fishes. For the rest I refer you to my paper from Paris, and impatiently wait for your judgment, for which I have a particular esteem."
