PROCEEDINGS OF THE BOARD OF REGENTS. 91 



ViENiVA, February 9, 1864. 



My Dear Sir : Permit me to enclose here au invitation to join in a subscrip- 

 tion for a gold honorary medal to be presented to our most worthy Professor Ch. 

 Fr. Ph. von Martius, of Munich, on his fiftieth anniversary of medical doctorship 

 on the 30th of March, 1864. 



Our most honored friends on the other side of the Atlantic should not fail in 

 the list; only I am sorry that by various impediments 1 was prevented from 

 writing at an earlier period. It is now so late that only by very good luck, it 

 will be possible that an answer may arrive previously to the ir)th of March, to 

 be entered in the first list which must be printed, embellis"hed, and then bound 

 up, and sent to Munich from Vienna before the 30th of March. Whatever is 

 brought to notice later than the 30th will be appended, and what comes to hand 

 after the 30th up to the end of June will be given in the first complementary 

 report to be published on the 1st of July. Nothing will be lost, as even what 

 comes after that period will be published afterwards. 



Every subscriber, of course, will have a bronze copy of the medal, and the 

 votary tablet sent to him. Subscriptions should be three florins Austrian silver 

 money, or more, which is about one and a half dollar American silver. 



By this time you may already have received our last box with tertiary fossil 

 types of several localities of the Vienna basin, being a joint parcel from the 

 Imperial Mineralogical Cabinet and our own Geological Institution. 



I am happy to hear you have now the Ainsa Tucson meteoric iron. I shall 

 send some of these days a paper of mine on the Carleton Tucson, which ap- 

 peared in the Vienna Academy Proceedings. I enclose impression from the 

 surface, cut, polished, and etched, and galvanographed positively and negatively. 

 We shall be happy, as soon as you may fix on cutting some slices off the block, 

 to receive a bit from you for our Imperial Mineralogical Museum of the Ainsa 

 Tucson too. 



With all the most cordial wishes, ever most truly yours, 



W. HAIDINGER.

Montreal, February 26, 1864. 



My Dear Sir : Absence from home and subsequent indisposition have pre- 

 vented my acknowledging receipt of your letter of 19th ultimo at an earlier date. 



The settlement you have made of Mr. Kennicott's account is quite satisfac- 

 tory. There was a small deficiency in consequence of a change in the rate of 

 exchange when your draft reached me ) but that matter can be arranged when 

 we receive Mr. Mactavish's final statement of Mr. Kirkby's account. 



The kind expressions of thanks contained in your letter are very gratifying. 

 We have always felt pleasure in promoting scientific research ; but, in Mr. 

 Kennicott's case, this was enhanced by his amiable character and prudence. It 

 is no easy part to play, going as a stranger into a territory inhabited by men 

 bound to a foreign government, and with exclusive views on many points. But 

 Mr. Kennicott knew how to meet the circumstances ; and from his arrival among 

 us until his departure was always popular, and I believe inspired a sincere 

 friendship and esteem among those with whom he most associafed. If in 

 Washington, pray offer him my kind regards. 



Hoping some day to have the honor and pleasure of forming your personal 

 acquaintance, believe me, sir, very truly yours, 



EDW. M. HOPKINS.
