400 Letter from B. A. Gould. 
do its utmost to aid in the photographic work, and with this view 
desired to order the new object-glass and to provide for the pay 
of my photographic assistant. The place of Professor of Payee 
in the scientific corps now organizing here was not yet filled; and 
I was informed that if I deemed Dr. Sellack a fit person, he shoul 
be appointed at once, with orders to go on dog the phos 
work under my di irection, feolvng im for a season from all 
finally obtained his appointment, which dated from the beginning 
of the present Shad and was accompanied by the instructions 
already mentio 
This ri ae Meliss of facts seems to be called for under the 
circumstances, and obviates all necessity of comment upo on the 
propriety or contents of the article to which I i whieh I 
will cite a few par ie eeere 
“Under an ath ment made with Mr. Rutherfurd in New 
York, at the expense of some gentlemen from Boston, I went to 
Cordoba, to take in the Argentine National Observatory photo- 
graphs of southern star clusters 
“As the circumstances have been utterly unfavorable, ...-- > 
the results of the enterprise could not fulfill the legitimate Gxpee 
tations of the liberal originators.’ 
“T selected and photographed some twenty star clust f 
“The elaboration of the results which the plates are acai e 
eiying has been reserved to Dr. Gou 
e Argentine Government is going to provide a new photo- 
setuhie lens for the National Observatory, and has asked me to 
continue the experiments with the new lens.’ 
I likewise waive all comment upon ve statements of the same 
paper vii possess a scientific bearing. Mr. Ru therfurd ve 
always freely communicated such of his methods and nae = 
he has not published. As for myself, never having yet made wie 
is called a scientific reclamation, I am indisposed to begin on 
occasion ;—and it is certainly not incumbent upon me to C0 
such of the statements as are erroneous.
