Besides copies of all the sumptuously-illustrated monographs, the 
Library is especially rich iu “ Old Authors ”—rather a hobby of 
Newton’s,—many of them reputed to be of great value. He was 
well known as a bibliophile, but whether a book or pamphlet was 
old or new, he never hesitated to write freely in it critical notes, 
cross-references which he alone knew of, corrected dates, &c., and 
thus he greatly enhanced the value of his books to anyone who may 
wish to consult them. 
The Newton Library is not a public nor a lending library, but 
eveiy facility for its study in a we Unfitted room is, and will always 
be, gladly given. 
Some impatience has been shown about the accessibility 
of these collections of books and eggs. Their sudden ac¬ 
cession raised several difficult problems. Not only does it 
take time to sort and rearrange such an influx, but it 
requires space in an already more than crowded museum : 
and (given time and space) also binding, cabinets, show¬ 
cases, catalogues, all costing money, which is well known 
to be scarce in the case of our Alma Mater.

and 1904. I was in hopes that Mr. Foster would have been 
able to send me some account of the locality and the 
circumstances under which the collection was made, but I 
have not yet heard from him on the subject. 
Sapucay, as will be seen by the map (text-fig. 1, p. 54), is 
situated in about 57° W. Long, and 27° S. Lat. It is on the 
railway between Asuncion and Ybytimi. 
Since the time of Azara, several isolated papers have 
appeared dealing with the birds of Paraguay, but I do 
not believe that any collection of such magnitude as that
