626 Catalogue of Works on Gardening, S;c. 



throughout the county." There is an excellent article, by Mr. Curtis, on the 

 different insects affecting the turnip crop ; and one, by Professor Henslow, on 

 the i^Lingi producing rust and mildew. Besides these articles, which interest 

 the gardener as well as the farmer, there is a copious review of Professor 

 Daubeny's lecture on manures. The purely agricultural papers are numerous 

 and varied. 



The British Farmer's Magazine for 1841. In monthly numbers. 8vo. 



3s. each. 



There are many excellent papers in this work, which is very greatly im- 

 proved since it came under the management of the present editor. Many of 

 the articles are as interesting to the gardener as to the farmer, particularly the 

 papers on vegetable physiology, draining, and the editor's tours. 



The Entoviologist. Conducted by Edward Newman, F.L.S., Z.S., &c. ; 

 many years Editor of " The Entomological Magazine;" Author of 

 " Sphinx vespiformis," " The Grammar of Entomology," " History of 

 British Ferns," &c. No. IX. for July. In monthly numbers. London, 

 1841. 6*. each. 



A periodical which will be as acceptable to the entomologist, as the 

 Phytologisty edited by the same author, is to the lover of plants. We sin- 

 cerely wish both journals that success which they so well deserve. 



Brande^s Dictionari/ of Science, LHeratitre, and Art, ^c. Parts II. to VIII. 

 We have strongly commended this work in p. 177., and the numbers now 

 before us justify our again recommending it to our readers, as the best 

 substitute for a scientific encyclopaedia extant in the English language. 



Lectures on Chemistry, including its Application in the Arts. By Henry M. Noad, 

 Lecturer on Chemistry ; Author of Lectures on Electricity, &c. In 8vo 

 numbers. London and Dublin, 1841. 1^. each. 

 We fear this work is rather too dear to obtain an extensive circulation. 



The Eighth Annual Report of the Royal Cornwall Polytechnic Society. 8vo, 



pp. 100; with a woodcut. Falmouth, 1840. 



We have noticed the Seventh Annual Report of this Society in p. 177.: 

 that before us contains various interesting papers, including three meteorolo- 

 gical registers for 1840, with remarks on the weather of that year. The 

 articles are illustrated by five lithographic prints, 



Model Mapping, as suggestive of a general and economic System of Drainage 



and Irrigation, SfC. By J. Bailey Denton, Surveyor, Gray's Inn Square. 



Model mapping has been a favourite object of ours since 1805, as will 

 appear by the following extract from the Farmei-'s Magazine for that year. 



" We have seen, at Mr. Loudon's, two models of the North Berwick 

 Estate ; one showing the present appearance and contents of the estate 

 in general, and the other showing the effect of an intended new place of 

 residence for the proprietor (Sir Hugh Hamilton Dalrymple). In addition to 

 this last model, there is an elegant manuscript volume, illustrated by drawings 

 and sketches, containing Mr. Loudon's ideas of the place, his reasons for pro- 

 posing the improvements, and practical directions for executing them; ac- 

 companied with ivorking plans, a large vertical profile showing the effect of 

 the whole, and a general estimate of the expense. 



" Mr. Loudon, we understand, intends to send duplicates of the above 

 models, plans, &c., to No. 4. Chapel Street, Bedford Row, his lodgings in 

 London; where, or at No. 7. Terrace, Edinburgh, they may be seen and 

 examined by any gentleman who shall take the trouble of calling." {Farm. 

 Mag., vol. vi. p. 127.) In the preceding page of the same volume are 

 enumerated the advantages which it is supposed will attend this mode of 

 imitating estates.
