Drew—On Christ Church Cathedral. 215 
shows the old Four Courts, and the passage then colloquially known 
as ‘‘ Hell,” the Exchange, and, as the schedule quaintly sets forth 
among other things, ‘‘the place where the Stocks is”’ ; it delineated 
the many houses and small tenement holdings in Skinner-row, now 
swept away, and the two ‘‘yards” surrounded by shops and small 
booths intervening between these and the south side of the cathedral. 
Looking at Sedding’s map, the last thing that would strike most 
people would be to develop the plan of a monastery out of it. Views 
of the cathedral from the south-east, given by Grose in 1791, and 
drawn as late as 1821 by George Petrie, give a rude notion of what 
the ‘‘ Exchange”’ was. Itis at once recognizable as a mediseval groined 
building, and Sedding’s schedule sets forth the chambers over it. I 
have no doubt those very ones offered by an advertisement in a Dublin 
paper of that time— 
“To let, apartments in Hell. 
N.B.—Well suited to a Lawyer.” 
Further information as to the ‘‘ Exchange” was given me from a map, 
the accuracy and authenticity of which I cannot well doubt, from its 
internal evidence, although the sources from which it may have been 
compiled are a mystery. 
Bound up in Kelly’s new (and uncompleted) edition of Arch- 
dall’s Wonasticon Hibernicum, vol. ii., isa map of Christ Church Cathe- — 
dral and precinct, evidently not drawn for this work. The text has 
no reference to it, and the reference figures on it are sought for in the 
body of the work in vain as having any meaning. I have, however, 
ascertained that this map was intended for a work by William Monck 
Mason, never published. It would appear that his well-known history 
of St. Patrick’s Cathedral was not intended to be a monograph, but 
the first instalment of a great and ambitious work, Hibernia Antiqua 
et Hodierna, being a Topographical Account of Lreland, and a History of 
all the Establishments in that Kingdom, Ecclesiastical, Civil, and Monas- 
tick. 1 have the prospectus of the volume relating to Christ Church 
projected in 1819. This projected volume never saw the light, and 
the MSS. and raw material collected for it found their way to what 
is known as'the Phillips collection, locked up from scholars at Chel- 
tenham. ‘The steel plates intended for it were sold at an auction in 
London, bought by Mr. Kelly, and inserted passim in his new Jonas- 
ticon Hibernicum, to adorn the work, merely. Mason’s map gives the 
Exchange as a four-bayed groined building. 
It scarcely needs a glance from anyone acquainted with the typical 
monastic plan and its varieties to recognise this building as the ancient 
CHAPTER-HOUSE in its usual and expected place with reference to the 
church. It stands east and west, about seven feet away from the south 
transept, and the views above referred to show us the monks’ dormi- 
tories over it. The passage that intervenes between the chapter-house
