THAT the French should know better than any other nation how to enlist art in the service of science is just what might be expected. Such a service on the part of art to science is only a fair return for the immense resources which scientific research has been able to place at the disposal of art. Nowhere have the discoveries of science been more useful or more utilised than at the celebrated porcelain manufactory of Sèvres, and the illustrations which we give to day will afford some idea of the beautiful results which are thus produced. As a permanent record of successful scientific efforts, nothing could be more, satisfactory and appropriate. In Fig. 1 the characteristic features of the Arctic regions are rendered with almost perfect success and truthfulness; while the allegorical representation in Fig. 2, in commemoration of the last transit of Venus, is happy in conception, and charming in effect. Of the artistic merits of the two vases our readers, can judge for themselves. It may be interesting to give some idea of the difficulties attending the manufacture of such delicate productions, which we are able to do, from a lecture by M. Ch. Lauth, Administrator of the Sèvres manufactory, published in La Nature, to which journal also we are indebted for our illustrations.
