It was generally felt at this time that some new system must be adopted for the warming and ventilating of great public buildings. Hence, the very novelty and comprehensiveness of Dr. Reid’s plan tended to recommend it to public notice, in spite of much scepticism on the part of practical men. Accordingly, in January, 1840, he was formally appointed at a fixed salary, to superintend the warming and ventilating of the New Palace. This appointment was made, without any consultation with the architect, and without any provision whatever as to the relative subordination of the two authorities thus created. What limit (if any) should be put to Dr. Reid’s requirements of accommodation in space and position, how they were to be reconciled with the æsthetic or constructional character of the design, where the ultimate responsibility was to lie, if the efficiency of the building were seriously affected--all these questions were left undetermined. Nor was any authority provided, to which appeal could be made, if any important difference of opinion should arise between the architect and ventilator. Division and disagreement were the inevitable result of this state of things. In consequence of Dr. Reid’s requirements alterations became necessary in every quarter of the building. The central tower itself was originally designed to furnish a great ventilating shaft, though it was afterwards gladly retained as an architectural feature. Finally it appeared that about _one-third_ of the whole cubic contents of the building was to be surrendered to Dr. Reid; and it was the opinion of Mr. Barry that the construction would be seriously affected by the ventilating arrangements, and especially that the “fire-proofing” ordered by the Government was all but nullified. This led to a decisive rupture,[71] attended of course by much controversy and mutual recrimination, into which it would now be needless and improper to enter. The Government determined to refer the case to professional arbitration; Joseph Gwilt, Esq., was selected as arbiter. After a long and careful examination of the statements made, and papers presented by both parties, he made a report in September, 1845, stating his opinion, first, that Dr. Reid’s system, by the use of vertical flues, destroyed the fireproof character of the building, and, next, that the delay which had taken place was mainly due to the division of authority, and the want of detailed drawings explaining Dr. Reid’s views and requirements. He added a recommendation, that the whole authority over the building should be restored to the architect, but that he should be directed to call to his aid some “experts” in ventilation, and to act by their advice.
