beautiful lantern transparencies of Volvox globator illustrating this section. 
Diatoms were next placed before the audience, being illustrated by three slides, 
the Jsthmia nervosa, Licmophora flabellata, and Pleurosigma angulatum. 
This brought the lecturer to the fungi, really the ‘* Queer plants” of the 
evening, and of which many specimens were thrown upon the screen. There 
was the Peronospora infestans, or potato disease, which last year produced such 
havoc amongst our crops; and the wheat mildew, or Puccinia graminis, to be 
found in every corn field. The wheat-bunt, or 77//e/za caries, was also exhibited, 
being drawn upon ground glass by the lecturer, colored, and finally varnished 
as recommended by Rev. W. H. Dallinger. 
The mildews which attack decaying substances were next treated upon; 
they are generally styled black moulds, and there are many forms for study. 
The lecturer gave illustrations of some of the many forms he had found on cotton 
goods, such as Helminthosporium, Macrosporium, and Mucor, while some, as 
the Dactylium dendroides and Triposporium elegans, were beautiful transparen- 
cles.
