=Features of the Collection.=--The result of the expenditure with which successive Parliaments have thus supplemented private gifts has been to raise the National Gallery to a position second to that of no single collection in the world. The number of pictures now on view in Trafalgar Square, exclusive of the water-colours, is about 1600.[10] This number is very much smaller than that of the galleries at Dresden, Madrid, and Paris--the three largest in the world. On the other hand no foreign gallery has been so carefully acquired, or so wisely weeded, as ours. An Act was passed in 1856 authorising the sale of unsuitable works, whilst another passed in 1883 sanctioned the thinning of the Gallery in favour of Provincial collections. There are still many serious gaps. In the Italian School we have no work by Masaccio--the first of the naturalisers in landscape; only one doubtful example of Palma Vecchio, the greatest of the Bergamese painters; no first-rate portrait by Tintoret. The French School is little represented--an omission which is, however, splendidly supplied in the Wallace Collection at Hertford House, now the property of the nation. In the National Gallery itself there is no picture by "the incomparable Watteau," the "prince of Court painters." The specimens of the Spanish School are few in number, though Velazquez is now finely represented; whilst amongst the old masters of our own British School there are many gaps for some future Vernon or Tate to fill up. But on the other hand we can set against these deficiencies many painters who, and even schools which, can nowhere--in one place--be so well studied as in Trafalgar Square. The works of Crivelli--one of the quaintest and most charming of the earlier Venetians--which hang together in one room; the works of the Brescian School, including those of its splendid portrait painters--Moroni and Il Moretto; the series of Raphaels, showing each of his successive styles; and in the English School the unrivalled and incomparable collection of Turners,--are amongst the particular glories of the National Collection. Historically the collection is remarkably instructive. This is a point which successive Directors have, on the recommendation of Royal Commissions, kept steadily in view; and which has been very clearly shown since the successive re-arrangements of the Gallery after the extension in 1887.
