AT MAGDALEN COLLEGE 15 



Astronomical Apparatus. The 5J-inch refracting telescope 

 by Cooke was mounted upon the brick arch constructed by 

 Buckler. 



There are also in the Laboratory two smaller telescopes, 

 a si-inch refractor of 44 inches focal length, purchased 

 from Dollond in 1836 by the Rev. Joseph Cox for 78 15^., 

 and a 4-inch Gregorian reflector, having a silver plate 

 engraved with the arms of Magdalen College and of the 

 donor, and bearing the following inscription : Coll. Magd. 

 Oxon. D.D. Ricardiis Persehowse de Walsall in Com. Stafford. 

 Armiger. Hujus Collegij Sup. Ord. Commensalis & A.M. 

 A.D. 1755. 



Physical Apparatus for the performance of experiments on 

 Voltaic Electricity, Pneumatics, Hydrostatics, Light and Heat, 

 was contained in the cabinets i-x in the gallery of the Lecture 

 Room, while the Static Electricity and Electro-magnetism 

 instruments were grouped in cabinet xxiv in the Apparatus 

 Room, which, being built against a flue, was always dry 

 enough to preserve the frictional machines in working order. 

 Among -the treasures of the collection is the early form of 

 Spectroscope by Elliott 1 , with immovable telescopes and a 

 hollow glass bottle prism which was presented to Dr. Daubeny 

 by Bunsen. 



The Collection of Chemical Substances found a place in the 

 remaining cabinets x-xiii in the Lecture Room and also in 

 the cabinets against the east wall of the Apparatus Room. 

 The series of specimens had evidently been collected with 

 considerable care, but owing to the imperfect stoppers to the 

 bottles, to loss or obliteration of labels, or to corrosion by 

 fumes, it is of little value now and will have to be recon- 

 structed. 



The other cabinets, xvii-xxiii, in the Apparatus Room 

 contained Organic Products and apparatus for analysing the 

 same, as well as apparatus for showing endosmose and ex- 

 osmose. 



The Glass, Earthenware, and other Apparatus for ordinary 

 use in the Laboratory was chiefly contained in the cupboards
