28 NOTICKS OF ROOKS. 



the question has been settled by Dr. Tiimen, who favoured mc with 

 the following? opinion, on receiving a specimen or two from me : — " I 

 have little doubt that the Dock is what we call in England R. maxi- 

 mus, or, as I prefer to call it, li. Ilydrolapathum, var. latifolms, Borrer. 

 It is perhaps a little off the strongly-marked Lewes plant, but is quite 

 like another of Mr. "Warren's Sussex specimens from Slioreham. You 

 will be glad to know that Mr. Warren agrees in naming your plant 

 maximus." So we find this Dock occurring in the widely separated 

 counties of Cornwall and Sussex. — T. li. Akchek Ekiggs.

The mere accumulation of specimens in any branch of natural 

 science must never be confounded by the collector with a knowledge of 

 the science itself, yet when properly used nothing so effectually assists 

 the learner as the actual possession and leisurely examination of a well- 

 assorted collection of realities illustrative of the subject at which he 

 is working ; for it is universally admitted by all who have anything to 

 do with science-teaching that the actual demonstration of a fact is of 

 far more value to a student than any amount of verbal reiteration. 

 Hence one great use (but by no means the only one) of herbaria, and 

 ii is from this as well as from otlier causes that so many mycological 

 exsiccates find subscribers. The professed objects of these publications 

 are various. Some, for instance, represent the distribution of certain 

 Orders, others, and a more numerous class, illustrate the flora of 

 various districts or countries ; while one publication consists solely of 

 economic Fungi, including useful and baneful species. The " Myco- 

 theca Universalis," however, has a far more extensive object — namely, 

 to illustrate the mycological flora of the whole world. As a matter of 

 course, the success must rest in a great measure with the willingness
