As a rule, observations which exist only in the form of annual catalogues, like 
the Radcliffe observations following Radcl 60, the Cambridge observations fol¬ 
lowing Camb 30, and some others, were not employed in the present computations. 
An exception to this practice exists in the case of declinations of the principal 
standard stars contained in the author’s former work, Declinations of 500 Stars; 
for these the authorities therein given were also employed as they had been pre¬ 
pared in the manuscript of that work. Nor was it considered advisable to make 
any special effort to secure all the results of available catalogues which may now be 
existing in manuscript at the respective observatories. Yet some requests for such 
material have been made from here in several instances, and have met with most 
generous response, as indicated in the following list: 
Berl 90. Manuscript catalogue of 1300 stars for 1890 from Kiistner’s meridian-observations at 
Berlin, sent by Professor Ktistner. This catalogue includes the results published in 
Ast. Nach., Nos. 3392 and 3393. 
Melb 90. Melbourne General Catalogue of 3068 stars for 1890, manuscript copy, forwarded by 
Director Baracchi, together with copies of many annual catalogues of stars observed 
in the interests of the astrographic work.
