266 Office of the Gland 



be dear in proportion to the expense attending their public- 

 ation, I cannot judge; and I want to be put into a knowledge 

 of " the proper sources " through which I may be able to ob- 

 tain such works at one third of their published price. I want 

 this for two reasons : first, because I cannot afford to spend 

 much money for books ; and, secondly, because I don't choose 

 to be " cheated." As, however, one fact is worth a thousand 

 theories, I will feel much obliged if Mr. Wood will inform 

 me how, and where, I can get the following works at one 

 third of their published price: The Transactions of the Lin- 

 ncean Society, The Transactions of the Horticultural Society, 

 The Transactions of the Geological Society, Sweet's botanical 

 works, Haworth's work on British Lepidoptera, Hooker's 

 Monograph of the Jungermannia, Lindley and Hutton's Fossil 

 Flora, Griffith's Cuvier, Selby's British Birds, Stephens's 

 Illustrations of British Entomology. I know of no means, at pre- 

 sent, by which I can obtain these works, and a long catalogue 

 of others which I could name, but at the published price ; and, 

 therefore, I am obliged to be content (or rather discontented) 

 without them. If Mr. Wood will have the goodness to in- 

 form me how and where I can procure them for one third of 

 the published price, I am sure he will not only be rendering 

 me, but also the public in general, a most essential service. —

Mr. C. T. Wood's Remarks on the extravagant Price of 

 Works on Subjects of Natural History, (p. 213— 216.) — I 

 quite agree in the remarks of C. T. Wood on the extravagant 

 prices of books of natural history. It has always appeared to 

 me great folly to dress up "working books in fine array, and 

 thereby prevent their general use and extensive sale ; the for- 

 mer, a public, the latter an individual, evil: for, if brought 

 out at a moderate price, hundreds would be benefited, instead 

 of tens ; and the same ratio of profit would reward both au- 

 thors and booksellers. — Phi. April 10. 1836. 



[ The Question of the Office of the Gland upon the Rump of 

 Birds, (p. 158—164.)] 



\_A Correction of an omission, which Mr. Waterton has 

 advised us of our making in his last published communication 

 on this subject. In p. 159., lines 22 — 26., for "A very mo- 

 derate attention to ornithology would have taught him that 

 there are birds with tails and birds without tails. So," read 

 " A very moderate attention to ornithology would have taught 

 him that there are birds with a tail and birds without a tail. 

 AU birds with a tail have invariably a rump, and, of course, 

 tiiey must have the oil gland. All birds without a tail have 

 no rump ; of course they can have no oil gland. So."]
