VII. MISCELLANEOUS. 



Lens Testing. Daring the year 31 lenses have been tested ; of these 

 13 received class A and 18 class B certificates. These numbers 

 though small show a gratifying increase on the two previous years. 



The testing apparatus has been the subject of a good deal of in- 

 terest, several practical opticians of eminence and others interested 

 in photography having inspected it and enquired into the details of 

 the various tests. 



Library. During the year the library has received as presents the 

 publications of 



26 Scientific Societies and Institutions of Great Britain and 



Ireland, and 

 108 Foreign and Colonial Scientific Establishments, as well as of 



numerous private individuals. 



During the summer a partition was removed which used to divide 

 the library into an outer and an inner portion. The conversion into a 

 single room has greatly improved the appearance of the library, and 

 has been found advantageous in various other ways. 



Loans, fyc., Repaid. The Royal Society have been repaid half their 

 loan of 400 made last year towards defraying the cost of the new 

 building, and also the unspent balance L17 Is. Td. of the pen- 



i dulum account. 



Paper. Prepared photographic paper has been procured and sup- 

 plied to the Observatories at Aberdeen, Oxford, Stonyhurst, Lisbon, 



; Mauritius, St. Petersburg, Toronto, and through the Meteorological 

 Office to Batavia, Fort William and Valencia. Plain Papier Saxe 



i has been sent to Coimbra Observatory, anemograph sheets to the 

 Hong-Kong and Mauritius Observatories, and blank forms for the 



' entry of magnetic observations to the Observatories at Falmouth and 

 Valencia, and to the Science and Art Department, London. 



Souse, Grounds, and Path. These have all been kept as usual during 

 the year. In view of the increased and increasing extent to which the 



I Old Deer Park is now allotted to athletic clubs and other associations 

 having for their object the public amusement, negotiations have been 

 entered upon with the Office of Her Majesty's Woods and Forests for 

 the purpose of securing ampler protection to the Observatory. 



Subjoined to this Report will be found a list of instruments, 



; apparatus, &c., the property of the Incorporated Kew Committee, at 

 present lent to various institutions and scientific men.
