Letter from Dr. Weissenborn. 513 



in the coral and in the surrounding atmosphere, which, be- 

 ing decomposed, gives out a sufficient quantity of each to 

 unite in the proportions necessary to form this beautiful light. 

 I may be wrong in my solution of the cause, but the light is 

 so very brilliant, and so easily produced, that I shall be sa- 

 tisfied if I have the good fortune to draw the attention of any 

 chemist to the fact. I have sent you several specimens for 

 distribution among your friends, and will procure more for 

 you if you wish. — Idem. 



Letter from Dr. Weissenborn. — It was not till yesterday 

 that I had an opportunity of seeing the numbers of your Jour- 

 nal from April to July inclusive ; and I feel particularly obli- 

 ged to you for the insertion of my articles, as I am quite aware 

 that, whatever share of intrinsic merit they may possess, the 

 concomitant circumstances must come in for a large one, to 

 make them sufficiently interesting to a public, whose Jour- 

 nals have become the depositories of almost all that genius 

 and talent, assisted by science, successively produce in your 

 country. 



In perusing the article on the Bos urus I have found a few 

 errors of the press, which I shall avail myself of this oppor- 

 tunity to point out. At p. 239, 1. 12, (May number), read 

 ' Haemus' for 'Hacmus;' p. 244,1. 23, read 'Monapos" 1 for 

 'Monassos;'' p. 246, 1. 4 of the notes, read ' Sph<era* for 

 ' Sphacera ; ' same page 1. 15, read ' acciperentur^ for 'acci- 

 pirentur ; ' 1. 17, read ' armentd* for ' arminta ; ' p. 251, 1. 

 26, and p. 252, 1. 2, read ' Masovia ? for ' Muscovia ; ' p. 252, 

 1. 12, read 'rather absenV for 'absent. ' Herberstein does not 

 say that he was absent when he received the present in ques- 

 tion, but it appears from what he states about it, that he paid 

 little attention to the carcass, which was sent to his kitchen. 

 See also the first note on p. 252. At p. 306, 1. 24, (June), 

 read 'and the frontal bone is convex? instead of 'and are con- 

 vex ; ' p. 312, 1. 28, read 'an entozoon* for 'or entozoon? 



My opinion that the Uerox of Mount Caucasus is of a spe- 

 cies different from that of Lithuania, which had already re- 

 ceived some confirmation by Prof. Nordmann's statement, 

 (see July No. ' Mag. Nat. Hist.'), " that the former descends 

 into the valleys in consequence of much snow falling in the 

 mountains," which proves it to be a mountain animal, — has 

 just received additional support through a communication in 

 the June No. (1838) of the Treussische Provinzialblatter," by 

 Dr. H. Pathke, the Director of the Zoological Museum of 

 Konigsberg, in Prussia. Among the remarks which he makes 

 on the stuffed specimen of the Bos urus which has lately been 

 added to the collection, I find that Dr. Koch, who has lately
