I wonder if you recognize the: 



!. ?Cactearum alig. nov. if it is something new for you and I will look for it. 



2. The ? Geonographia has been placed in 12 volumes with magnificent plates on 

 colored leather, hand made, with 2 columns of French lettering. It was written in 1841- 

 1843. Its publication was interrupted by the death of the editor in Belgium. 



I will research thèse two volumes during my next trip to Paris and I will be able to tell you 

 about them, this year. 



3. I do not have any of the work from Haworth. 



4. ?Hortus dyckensis. The next time I will try to find it in the numerous libraries. I 

 receive the catalogues ad hoc. 



5. Scheidweiler, he only published prolonged notes in the ???? , that have no great 

 importance, in Belgique Journals and in the German "General Garden Newspapers". He 

 never published in the Annals of the Agricultural and Botanical Society of Ghent. 



6. De Candolle thanked me for having assisted him on the occasion of having a public 

 sale of one of his works. It is an absolutely abominable work in regards the colored 

 plates. 



7. Martius "New Napoléon". Small insignificant brochures inserted in the Nova Acta 

 Nature. They can nearly not be found. 



8. But another article from the same author with pamphlets that have beautiful plates, 

 which you do not mention perhaps because you have such few samples. I will try to get 

 some for you from Germany. 



The two or three other works that you mention to me are not related to the Cacti. I 

 would not have them. 



Well, then it would be good to renew our communications which will be a pleasure for 

 me and for you. You could be one of the patrons of my Monographie Review of the 

 Cactaceas. I will be happy to publish them. 



I will adopt as a separate gender your Cylindropuntia and wll shorten its name to 

 Cactus, which logically will remain as part of the family. My gender Consolea includes 

 the Opuntia with flat stems, ramified only lateraly and on which the flowers are located 

 as a circular base on the top, forming a cupula. I observed with Mr. Console, the 

 Opuntia spinosissima, rubescens. 



My letters do not give you more détails of my innovations, however I must say that this 

 work is complète in ail points and irreproachable in regards the Cacti. I have been 

 lucky to have been able to study them when they were sent to me alive from a 

 temperate climate. I have been able to divulge my information to différent herbariums in 

 Europe. 



You had the kindness to make available to me your three beautiful volumes where I 

 admired the magnificent créations, that would be difficult to duplicate in Europe. I 

 received them with much gratitude. With their help I will complète my books and I will 

 have the honor of citing your name in them. So that they can arrive here, I believe the 

 only way is to send them on a British or American steamer from England or Antwerp or 

 Le Havre.
