Wat., taken by him, still exists in perfect condition in the Oxford University 

 Museum. Proceeding to Cape Town at the enl of 1810 the next two years were 

 occupied in his great and adventurous journey of 4500 miles in the wilds of South 

 Africa, far beyond the limits of civilization in Cape Colony. The narrative of this 

 expedition, " Travels in the Interior of South Africa" {2 vols 4to, Longmans, 1822 

 and 182i), is one of the classics of English travel, and is eminently worthy, in these 

 days of cheap re-issues, of being made more accessible to the general reader. Many 

 Natural History Notes of the highest value are embodied in this great work, and 

 among them Prof. P'oulton draws attention to one of singular interest to the student 

 of " protective resemblance ;" a large and sluggish Acridian grasshopper, Met/ione 

 anclersnni, Stiil, was observed by Burchell associated with a small species of the genus 

 of succulent plants, Mesemhryanthemum, both plant and insect bearing a striking 

 superficial resemblance to the small pebbles among which they were found. In those 

 of his note books that still exist are numerous entries testifying to Burehell's excep- 

 tional powers of observation ; among these, the notes on the close superficial resem- 

 blance of the Longicorn, Amphidesmus analis, to the Lycid beetles in company with 

 which it was found, and that of Promeces viridis, another beetle of the same group, 

 to a Fossorial wasp, are perhaps the earliest allusions to the now vast subject of 

 Mimicry in Nature. In 1825, soon after the completion of his book, Burchell once 

 more left England for South America, and after staying more than a year in Rio de 

 Janeiro, set out on his second great expedition through the heart of Brazil, from 

 Santos to Goyaz (being the first Englishman to visit the last named city), and down 

 the great river Tocantins to Para, It is much to be regretted that no narrative of 

 this journey was ever published, but Burehell's remaining Brazilian note books, like 

 those of his former travels, are full of valuable observations on the Natural History 

 of this prolific region. As a single instance bearing on our Science we may cite his 

 notes on the stridulation of Passalid and Prionid beetles, a habit until recently 

 quite overlooked ; and his observation of the same habit in a scorpion, of which no 

 American species was known to have the power of making a noise, led to the dis- 

 covery by Mr. Pocock in 1904 of an entirely new sound-producing organ in the 

 group. After his return to England in 1830 Burchell lived in retirement at Fulham, 

 occupied with the arrangement of his vast collections, until his sad death by his own 

 hand in 1863, in his eighty-second year. His entomological collections, which even 

 now are unapproached in the fulness and accuracy of the data attached to every 

 specimen, form one of the chief treasures of the Hope Department of the 

 Oxford University Museum, where they were deposited in 1865. An excellent 

 reproduction of a rare etclied portrait of the great traveller and naturalist forms an 

 appropriate frontispiece to this valuable paper.

Jolm Linnell, Jun. — The death of John Linnell in May last year has removed an 

 Entomologist who for many years was a very active collector in the neighbourhood 

 of Reigate and Redhill. The writer of this notice has often accompanied him on 

 excursions in search of Coleoptera, and especially of the species which occur in 

 sandpits, in which the locality is rich. The species of Ilyobates, Lamprinus, Calli-
