AS INSTRUMENTS OP EDUCATION. 19 



cine, viz., Profs. Gumming, Miller, Henslow, Clark, Bond, Sedgwick and 

 Paget. I give one question from each of these papers. In the paper on 

 Chemistry it is asked '' If nitric acid is decomposed by voltaic electricity, 

 in what direction are its elements separated ? " In the paper on Miner- 

 alogy it is required to "Enumerate the systems of crystallization in 

 which double refraction has been observed ? Describe the situation of 

 the optic axis ot axes with respect to the figure of the crystal in the pyra- 

 midal, rhombohedral, prismatic and oblique systems ?" In the paper 

 on Botany the examinee is required to " Describe the diseases in wheat 

 termed ear-cockle and ergot." In the paper on Comparative Anatomy 

 it is asked " Have any of the ringed worms true joints ? " In the 

 paper on Physiology it is asked " What appears to be a principal office 

 of the pancreatic fluid according to Bernard ? By the selection of what 

 species of mammal for his experiments was he enabled clearly to dis- 

 tinguish between the action of the bile and that of the pancreatic fluid 

 during life?" In the paper on Geology it is asked "What evidence 

 have we for a 'glacial period?' Assuming its existence as a fact in 

 the history of the earth, how do we fix its geological date?" In 

 the " general paper" we have the queries : — " How do we discover the 

 mean density of the earth ? " " What are the indications of its prime- 

 val fluidity ? " " What are the present indications of an increasing 

 internal temperature ?" '' State some of the modern theoretical inves- 

 tigations bearing upon the question of the actual internal fluidity of 

 the earth, and the results derived from them." 



The Fitz-William Museum at Cambridge is not peculiarly adapted 

 to the necessities of the Natural Science student. It is a magnificent 

 collection of sculptures, paintings and books. Institutions that help to 

 the attainment of honours in the Natural Science Tripos at Cambridge 

 are the Anatomical Museum, the Geological Museum, the Mineralogical 

 Museum and the Botanical Garden. 



It would be superfluous to attempt a sketch of the British Museum 

 in London. In a collection so extensive and so scientifically arranged 

 the devotee of any speciality in Natural Philosophy will of course find 

 what will delight and instruct him. I will only add for the benefit of 

 any who are interested in meteors and aerolites that here they may see 

 and closely examine many hundred of these petty but eccentric 

 and not unformidable members of our system. After contemplating 

 thoughtfully the aspect, size and weight of several of these stray 

 vagrants from the outer space, all of which must be well-authenticated
