1S90.] MICROSCOPICAL JOURNAL. 205 



soiree was in successful progress. The illuminated building presented 

 a fine appearance from without. Inside it was filled with light and 

 life. It was estimated that between 3,000 and 4,000 people were pres- 

 ent during the evening. 



Four benches extended the length of the rink and every vard there 

 was a microscope for which a lamp furnished light. In all there were 

 over 175 microscopes, and the people were compelled to pass in one 

 direction around each l:)cnch. 



jVIost of the objects chosen for exhibition were those which would 

 best serve to engage and please the average visitor's attention rather 

 than those of the most particular scientific interest. Among them were 

 exquisite crystals of precious stones and metals, alloys, disease growths, 

 animal tissues, forms of vegetable and shell life, hair, the parasites of 

 various creatures, anatomical and physiological specimens, bacteria, 

 trichinae, micro-photographs. Kemmler's blood, gold, hairs of Egyp- 

 tian mummy, insect eggs, &c.
