Our next example, which is the portico of the Fitzwilliam Museum at Cambridge (Pig. 7), differs materially from the foregoing one, pre senting a richer system of columniation in some respects ; for though, technically speaking, no more than a monoprostyle octaBtyle, it is extended by lateral loggias, three intereolumns in width, and has besides considerable depth within.
Although only a hexastylo, the portico of the Kazan Cathedral, St. Petersburg, towards the Nevsky Prospect, is an unusually rich example of a polystyle prostyle, and of certain peculiarities of arrangement which will be better understood from the plan itself (Fig. 8) than from any verbal explanation. The cut also shows a portion of the sweeping colonnoles (in imitation of those by Bernini in the Piazza di San l'ietro at Rome), and the mode in which they arc connected, or rather not connected with, hut merely brought up to the portico itself, which is so awkward and disagreeable as materially to detract from the effect of the whole.
Mr. Gandy Deering's small Doric distyle in antis, in the front of the building originally erected for the Pimlico Proprietary School in Ebury Street (Fig. 9), affords an example of a portico with an inner
screen carried up half way behind the columns, and with lateral open ings at the ends of the portico between small niitai, a, a, ing as low as the top of the screen, and two of them resting on its exterior ends. The idea is a valuable ono, and admits of almost end less diversity and new combinations.
The only other examplowe shall offer is that of the semicircular, or rather segmental loggia, forming the north-westangle of the Bank of Eng land (Fig. 10), the must tasteful and picturesque piece of design that Sir J. Soano ever produced. The effect of the inner columns, the contrast they afford to the others, their shafts being plain, while the rest are all fluted, the varied perspective appearance accordingly as the spectator shifts his station, and the great play of light and shade, all render this little bit quite an architectural study.
