Economic Entomology applied to Food and Forestry.
This Collection, formed and arranged for the Department of Science and Art by Andrew Murray, Esq., F.L.S., is exhibited at the eastern end of the gallery, partly on the wall, and partly in glazed cases on the counter. It is intended to illustrate the ravages of such insects as are known to be destructive to alimentary substances, or that are noxious or injurious to man and domestic animals. Also, those insects known to be destructive to timber, or otherwise exemplifying the science of Entomology in its relation to Forestry. The Collection is contained in 42 cases, to which belong 31 framed diagrams and drawings. This Entomological Collection is yet incomplete, and may be considered as still in course of formation.
Adulteration of Food.
The extensive employment of various substances for the Adulteration of Food has led to the formation of a collection of those more commonly employed. In Cases 97 and 98 these substances are arranged according as they have been obtained from the animal, vegetable, or mineral kingdom. They have been selected principally from the results obtained by Dr. Hassall, and made known in his work “On the Adulteration of Food.”
The adulteration of Milk with Water is shown in Case 54. These examples are renewed weekly; and the use of the lactometer or milk measurer, is also exemplified in the same case. The goodness of milk can also be ascertained by means of the microscope. The diagrams on the wall represent good cream, good pure milk, bad milk, and the curd of milk as seen under the microscope.
