Ree. X nach Dec.21 f I856 Dyck v Nov. 30, 1856 * 



Ans. Jan 7. 1857 



* instead of giving the month f there is a stränge sign. I assume 

 November as the letter reached Dr. Engelmann on Dec. 21. This 

 2nd sign reads*^ nach? which I interprete as the letter having 



been sent w after w the Dr. on his trip. £~f disa^e^ : 'X nach " is £**el*»*i*ns 



Your Wellborn 



surprised ie with your letter from Frankfurt of the 24th very 



agreably; because I had given up hope seeing you this year.. Such a 



long trip can be made impossible by so many hindrances, that its exe- 



cution remains always uncertain.- As I assume, you took your way by 



France and Paris, and I shall reeeive you with the greatest of plea- 



sure at Dyck. There is now a railraod from Cblogne to Neuss-, and all! 



you have to do is to annouce the day of your arrivaliso that I can 



tß-^arrange for 



send a vehicle toward you. I as^you in advance Y&£ a sfeay of seve - 

 ral days; because I would like to show you everything, . and we could 

 not comraunicate in any other way.. 



The cacti, which you sent me in Spring, arrived f ine* and gave 

 me much pleasure».I; also, reeeived your Synopsis; unf ortunately», 



I do not have it in my hands at present, as I sent it to the bookbinder,, 

 to have this essay^combined with Plantae Lindheimerianae and the 

 Memoire. Your divisions suffice for the purpose of your essay;: na ~- 

 mely for the Organization of the native cacti of the United States.. 



II do not believe, that there will be many w double emplois M ((French^ 

 double employment, i.e. of botanical names, E.D. ) of species already 

 described* In any case, the work (unknown to me) by Mr. Scheer and 

 Seemann lacks all authority, and this remains entirely with your Syn- 

 opsis. - Objections, which I may have to make f . I reserve to your 

 presence at Dyck ; Your combination of the Mamillariae coryphantae », 

 where the large-f lowered species such as M. pyenacantha and scoljnno- 

 ld.es are united with the small-fl owering (in my opinion);
