Suplemento al anexo núm. 11, pág. 28 



De paso últimamente por Buenos Aires el señor profesor 

 B. A. Gould, Director del Observatorio Astronómico en 

 Córdova, he mostrado á él los pliegos ya imprimidos del 

 Boletín, para se impusiera de su contenido, y viendo el 

 anexo no. 11, me lia dicho, que los datos sobre la contrata- 

 ción del señor D. O. Sellack no son exactos, y me ha escrito 

 la carta^sigaiente, para corregir estas noticias, avisándome 

 que su informe, imprimido en el Boletín Oficial de la 

 Nación, Año IV. pt. 1. no. 883. pág. 302, dá los pormeno- 

 res de este asunto. 



Buenos Aires, Abril 22 de 1874, 



Dr. Burmeister. 

 My dear Sir: 



At your request y take the liberty of adding a few words of 

 correction to the accoimt given by you of the relations, which 

 Dr. Sellado held toward me. 



It is a mistake that this person was sent to me by any society 

 whatever. My endeovors to obtain a liberal subscription for this 

 purpose haviüg failed of fall success. T requested my fricud, Mr. 

 Rotherford in New York, to engage a photographer as my prívate 

 assistant, aud to cause him to be instructed in the astronomical 

 applications of his art. 



The photographer engaged was the person alluded to, who has 

 been known in this country under de ñame of Sellack. His 

 expenses of every kind, transportación, materials, apparatus, 

 salary and subsistance were depayed by me and by me alone; and 

 the theory of his having been sent by an American Society to the 

 work, for which I paid him, and which he did not perform, was 

 his own invention and without foundation in truth. 

 Very respectfully 



Tour friend and servant 



B. A. Gould.
