attention, and important industrial exhibits have been formed, showing the development of commerce and manufactures in western Pennsylvania.
It is far, however, from the purpose of the Trustees to restrict the Museum to the work which has just been outlined. The whole field of research is before them, and already very large accumulations of material from distant parts of our own continent and from foreign lands have been brought together. The collections already in the possession of the Museum may be approximately classified as follows:
|Botany (recent species)||17,000||100,000|
|Porifera, Echinoderms, etc.||500||1,250|
|Reptilia and Batrachia||150||1,750|
