%6i The Natural Hijlory 
In Hiort, this ft air- cafe feems to be a compofition of 4 
half-pace- open-newerd ^air-cafes^ as may ealily be perceived by 
thci^gures^ 123, 123, 123, 123, and 567, 567, $67, 567 , only 
communicating in the middle ; which indeed ftiews very riiagni- 
ficently, but has this inconvenience, that there is no paflagefrom 
one room into another though on the fame floor, without going up 
and down many fteps ; as in Scheme the fecond, if from a to b, 
andfoof the rooms of any of the other fides, you h^we no paf" 
fage but from 6 to 7, and fo down again to 6, i. e. 14 fteps. But 
if you are to go from corner to corner, as fuppofe from a to c, or 
htoJ, isr vice verfa-, whether you pafs round the fides, or over 
the middle half pace^ you cannot do it, without afcending and 
defcending in all twenty eight fteps. 
135. Of publick Buildings, the moft eminent in the County 
are certainly thofe of the Colleges and Halls^ the FuhlkkSchools, 
Library and Theater in the Vniverfitjof Oocford'^ of which yet in 
the whole I ftiall give no account, their magnificence and outward 
ArchiteSiure being already fufficiently fhewn,by the exquifite hand 
of Mr. David Loggan^ Chalcografher to the Vniverfity^ in his Cuts 
of them all lately fet forth. It (hall fuffice me therefore to give 
a fuccinft account of fome particular parts of them, whether in 
the fione or Timber-worky fcarce to be met with elfewhere, or 
known to few. 
136. Of the firft fort is the flat floor of fione over the paflage 
between the Right Reverend the Provofts Lodgings, and the Chap- 
pel2it Queens College^ born up only by the fide mils without any 
pillar^ though confifting of divers Jlones not reaching the walls^ 
which yet indeed may very well be, fince as I am informed by the 
fame Right Reverend Trovojl^ and Bifhop of Lincoln^ who pulled 
up the boards of the room above to view the curiofity ; the flones 
are all cuneoform^ and laid like that they call firaight Arch-work, 
137. The Roof of Merton College Treafury is alfo an odd piece 
of flone-vpork.^ being all made of Afiler^ yet (looping to an 
(only more acute than ufual) hke roofs made of Timber : It has, 
'tis true within, three inequidiftant arched ribs of fione thatfeem 
to fupport the Fabrick.-, which is about 20 foot long, but the flones 
not reaching from rib to ri3, and feeming to be laid like common 
pavement both within and without, make many to wonder that it 
does not fall in : but the Hones being pretty thick, and cut as they 
call
