used, and instances are not wanting where such a combination 

 exists, e.g., Cossus cossus, Vertigo vertigo, &c. If rule (4) be 

 adopted we shall have other cases, such as Nasturtium nastur- 

 tium L. ( = Nasturtium officinale Br.) &c. 



One or two additional rules may require to be framed to 

 meet certain special cases. To these, however, (or to the rules 

 of the nomenclature of families,) I shall not direct attention on 

 the present occasion. 



A BRITISH NATURALISTS' AGENCY. 



"\ \ TE have much pleasure in laying before our readers the 

 * following suggestions for the establishment of a " Natu- 



ralists' Agency" in Britain. The object of, and advantages 

 likely to accrue from, the institution of such an agency are fully 

 explained in our correspondent's letter, so that we need not 

 allude to them further than to say that we trust that such an 

 agency will be soon established, and to entreat all readers of 

 the Scottish Naturalist to assist. We shall be glad to answer 

 any enquiries about the matter. 



" Wishing as I do to call the attention of naturalists gene- 

 rally to what I believe to be a desideratum in this country, I 

 would be much obliged by the insertion of the following state- 

 ments and suggestions in the pages of the Scottish Naturalist, 

 with a view at some future time of seeing the suggestions laid 

 before the British Association for the Advancement of Science 

 for its consideration and support. 



A few years ago a Naturalists' Agency was formed at Salem, 

 Mass. U.S., N. America, and was called "The American Natu- 

 ralists' Agency." Since that time the Agency has flourished 

 and brought forth abundant and good fruit, and in an incredibly 

 short space of time has become the acknowledged medium for 

 the sale of the proceedings of all the learned societies in 

 America, and through which advertisers on all natural history 

 subjects make known their wants. The objects of this Agency 

 are stated at length in their prospectus, which is transcribed 

 further on. Some of the more important of these objects, how- 

 ever, I may be permitted more directly to call attention to.
