THE MICROSCOPE. 45 



long since obtained a well-deserved reputation. The names of 

 Chevalier, Frauenhofer, Oberhauser, Schick, Nachet, and many- 

 other continental opticians, here deserve honourable mention 

 for their various productions; and the author would be 

 wanting in justice and candour, were he not to acknowledge 

 the valuable information which has been derived in this 

 History of the Microscope from the excellent work of M. Che- 

 valier, entitled, Des Microscopes et de leur usage. 



The rapid progress of improvement in the manufacture of 

 the achromatic compound microscope in this country is con- 

 siderably indebted to the spirit of liberality evinced by the late 

 Dr. G-oring and R. H. Solly, Esq. To the patronage of the 

 former we owe the construction, by Tulley, of the first triplet 

 achromatic object-glass, that of the diamond lens, by Varley 

 and Pritchard, and of the improved reflecting instrument of 

 Ajnici by Cuthbert. To Mr. Solly is due the credit of 

 bringing before the public the improved microscope of Mr. 

 Valentine, the exquisite workmanship of Mr. Koss, and by 

 his intimate connection with the Society of Axts, and his 

 well-known liberality, he has been the means of making its 

 Transactions, since 1831, the vehicle through which nearly 

 all the improvements in the construction of telescopes and 

 microscopes, by Mr. Varley especially, have been made known 

 to the world. 



The late Dr. Goring, at whose instigation Tulley, in 1824, 

 constructed the first achromatic object-glass in this country, 

 said,* in 1829, "That microscopes are now placed completely 

 on a level with telescopes, and, like them, must remain 

 stationary in their construction." "Happily for us," says 

 Mr. Bowerbank,t "this prediction has not been fulfilled. 

 Admirable as were the combinations alluded to by Dr. 

 Goring, they were very far inferior to those which we now 

 possess, and which we, like the worthy doctor, are, perhaps, 

 inclined to believe are scarcely capable of being surpassed ; 

 but however beautifijl the combinations around us, let us 

 hope that the same skiU and talent which have wrought these
