Mr. Zentmayer displayed, among other instruments, one of his splendid 
binocular microscopes, which was greatly admired. Prof. J. A. Meigs 
exhibited, with others, an injected specimen of the gall-bladder, made 
by Dr. P. Goddard many years ago. 
Prof, B. H. Rand arranged upon a side table his spectroscopic 
apparatus, and from time to time demonstrated to eager spectators the 
spectra of different metals, and explained this new and exceedingly 
delicate method of analysis to the satisfaction of all.*
