inadvertently omitted under their proper head, 

 Infusoria. See plate XXXII. and XCI ; and arti- 

 cle Microscope. 



The Infusoria include all those minute animals, 

 most of them invisible to the naked eye, which 

 are found in infusions of vegetable and animal 

 substances. Their history has always been depen- 

 dent upon the powers of the microscope; and until 

 of late years, since the instrument has been greatly 

 improved both in power and delicacy, compara- 

 tively little was known regarding the Infusoria 

 beyond the fact of their vitality; and even this 

 was questioned by Buifon and others, who gravely 

 asserted their opinion that they were nothing more 

 than " active organic particles." Even Miiller 

 was unable to carry their history much farther 

 than the fact of their actual vitality; for his opti- 

 cal resources lacked the power to discover their 

 structure sufficiently to establish such analogy 

 between them and higher creatures, as would 

 allow them to take a definite position in zoology. 

 The recent advances of optical science, and the 

 indefatigable researches of Ehrenberg, have led to 

 the discovery of many new and interesting facts 

 regarding these minute creatures. It is now as- 

 certained that they are related by strong analogies 

 to the animal kingdom, though placed at the 

 extreme descending limit of vital existences. An 

 opinion was long entertained that they were 

 merely masses of gelatine matter, vital indeed, 

 but altogether nourished by absorption. This 

 erroneous impression has been removed by the 

 discovery of sacs or stomachs suited for the diges- 

 tion of food, and mouths curiously contrived for 

 securing and taking in the matter upon which 

 they feed. They who are curious to learn minute 

 particulars regarding the structure, functions, 

 instincts, and singular habits of the Infusoria, 

 would do well to consult Pritchard's " Natural 

 History of Animalcules," in which the subject is 

 lucidly treated and elaborately illustrated. Under 

 the article Microscope we have been permitted 

 to extract from this work, and to that article, in 

 connection with the illustrative figures in plate 

 XCI., we refer the reader for much interesting 

 information. We need not in this place add more 

 than the names of the several species of Infusoria 

 figured in plate XXXII., but not referred to under 

 Microscope, to which article the present one is to 

 be deemed supplementary.

WYATVILLE, SIR JKFFREY, R. A., F. R. S.. 

 F.S. A., a modern architect of some distinction, \\;is 

 the son of Joseph Wyatt, a builder at Burton-upon- 

 Trent, in the county of Stafford, where he \\:i< 

 born on the 3d August, 17G6. He was educated 

 in the free school of that town, and afterwards 

 placed with an uncle, then an architect of repute 

 in London, with whom he remained for seven 

 years: subsequently he entered the office of an- 

 other uncle, known as the builder of The Pantheon 

 in Oxford Street. In 1799, he joined in partner- 

 ship an eminent builder, who had extensive gov- 

 ernment contracts; and continued to pursue a pro- 

 fitable, though comparatively humble, career, until 

 the year 1824, when he was called upon to attend 

 and receive personal instructions from his majesty 

 George IV. respecting designs for restoring Wind- 

 sor castle. For this more important professional 

 object, he relinquished his pursuits as a man of 

 business. After a visit of the commissioners to 

 Windsor, and a liberal grant of money, the general 

 plan of operations was settled; and on the I "2th of 

 August, 1824, the anniversary of his majesty's 

 birth day, the first stone was laid. On that occa- 

 sion, the king conferred on the architect authority 

 for changing his name from Wyatt to Wyatville, 

 for the purpose of separating and distinguishing 

 the Wyatt of that reign from Mr James Wyatt, 

 who had been much identified with the architec- 

 tural works at Windsor, during the life of George 

 III. In December 1828, the king's private apart- 

 ments were completed, and on his majesty's tak- 

 ing possession of the castle, he bestowed the hon- 

 our of knighthood on his architect. Although 

 Windsor castle is the prominent professional work 

 of Sir Jeffrey, there are many other buildings, in 

 different parts of the kingdom, which have been 

 either wholly raised, or essentially improved, from 

 his designs. There is scarcely a county in Eng- 

 land, indeed, which cannot show some proof of his 

 art. For the last five years of his life, he laboured 

 under a disease of the chest, yet never abandoned 

 his profession. So late as -the close of 1839, he 

 designed the stables at Windsor castle, and lodges 

 for the Sheffield and Derby entrances to Chat- 

 worth. He died on the 18th February, 1840, and 

 was buried at the back of the altar in St George's 

 chapel, Windsor castle. As an architect, he was 

 distinguished for sound judgment, and a strong 

 faculty for arrangement under difficult circum- 

 stances.
