To remove the verdigris which forms upon the pins, the pinned insects should be immersed in benzine and left there for a time; several hours is generally long enough. The administration of this bath cannot be too highly recommended for beetles which have been rendered unrecognizable by grease, especially when dust has been mixed with the grease. This immersion, of variable duration according to circumstances, will restore to these insects, however bad they have become, all their brilliancy and all their first freshness, and the efflorescences of cupric oxide will not reappear. This preventive and curative method is also readily applicable to beetles glued upon paper which have become greasy; plunge them into benzine in the same way, and as the gum is insoluble in the liquid, they remain fastened to their supports. Pruinose beetles, which are few in number, are the only ones that benzine can alter; the others, which are glabrous, pubescent, or scaly, can only gain by the process, and they will always make a good show in the collection.--_A. Dubois in Feuille des jeunes naturatistes_, March, 1885, p. 71.--_Psyche_. * * * * * QUADRIGA FOR THE NEW HOUSE OF PARLIAMENT, AT VIENNA. [Illustration: QUADRIGA FOR THE NEW HOUSE OF PARLIAMENT, AT VIENNA.] The new House of Parliament at Vienna is known as one of the finest specimens of pure Greek architecture erected in this century; and throughout the entire building great pains have been taken to ornament the same as elaborately as is consistent with good taste. The main buildings are provided with corner pavilions, the atticas of which project over the roofs, and these atticas and other parts of the buildings are to be surmounted by quadrigas, one of which is shown in the annexed cut, taken from the _Illustrirte Zeitung_. This group was modeled by V. Pilz, of Vienna, and represents a winged goddess in a chariot drawn by four spirited steeds harnessed abreast. She holds a wreath in her raised right hand, and her left hand is represented as holding the lines for guiding the horses. The group is full of expression and life, and will add greatly to the beauty of the building to be surmounted by it.
