William Harrison, Esq., Queen's Counsel, a Bencher of the Inner 

 Temple, Counsel of the Treasury and War Office, and Attorney- 

 General for the Duchy of Cornwall, died at his seat at Cheshunt, 

 Herts, on the 4th of October last. He was eminently distinguished 

 in his profession, in the parliamentary business of which he for many 

 years took the lead. Those among us who have visited his retreat 

 at Cheshunt are not likely soon to forget the beautiful garden, with 

 its noble range of stoves and conservatories, which he had formed 

 there, or the kind hospitality with which they were received. Much 

 of his leisure was devoted to planting, and his garden exhibited, in 

 the great variety of trees and shrubs which it contained and the taste 

 displayed in their arrangement, ample proof of his attachment to that 

 pursuit. 



James Rawlins Johnson, M.D., F.R.S., #c, was author of "A Trea- 

 tise on the Medicinal Leech, including its medical and natural his- 

 tory, with a Description of its Anatomical Structure ; also, Remarks 

 upon the Diseases, Preservation and Management of Leeches," 1816, 

 8vo, London; and of two papers published in the ' Philosophical Trans- 

 actions' for 1817, entitled "Observations on the mode of Propagation 

 of the Hirudo vulgaris, or Rivulet-Leech," and " On the Hirudo com- 

 planata and Hirudo stagnalis, now formed into a distinct genus under 

 the name of Glossopora." These two papers were reprinted in 1825, 

 with some additional facts and observations, under the title of 

 " Further Observations on the Medicinal Leech." In these publica- 

 tions Dr. Johnson contributed much to the elucidation of the natural 

 history of the Leech, which has since been so ably completed by Ca- 

 rena and others. 



Aylmer Bourke Lambert, Esq., the last survivor of the original 

 members of the Linnean Society, and for nearly fifty years one of its 

 Vice-Presidents, was born at Bath on the 2nd of February, 1761. 

 His father, Edmund Lambert, Esq., of Boyton-House, near Heytes- 

 bury, Wilts., married Bridget, daughter of the last Viscount Mayo 

 and his only surviving child, through whom Mr. Lambert inherited 

 the family property and the name of Bourke. He was educated at 

 St. Mary's Hall, in the University of Oxford, and attaching himself 

 early in life to botanical pursuits, joined the Linnean Society at its 

 foundation, and became one of its warmest friends and promoters. In 

 1791 he also became a Fellow of the Royal Society. 



On succeeding to his paternal estate, he was enabled to indulge his 

 taste for botany more freely, and laboured with great ardour and suc- 

 cess to increase his herbarium, which at length acquired the charac-
