the pencil of Mme. Lavoisier introduce us into his laboratory 

 while he is conducting experiments in the respiration of a man 

 at work, and of a man in repose. After Lavoisier's legalized 

 murder, an inventory of his laboratory was made by a govern- 

 ment commission, among whom was the distinguished Nicholas 

 Leblanc. 



Accurate balances now became most important adjuncts to 

 chemical laboratories. 



Towards the close of the last century Italy contributed to 

 chemical research two inventions of marvellous power — the 

 Galvanic trough and the Voltaic pile, destined to electrify 

 material human progress. 



To sketch the development of chemical apparatus in this 

 century would prolong this superficial review unnecessarily ; 

 modern appliances are distinguished by careful adaptation of 

 the means to the end, and are improved by the introduction of 

 coal-gas for heating purposes, by the use of india-rubber tubing 

 and platinum vessels, and by the delicate products of the 

 glass blowers' skill. To these features may be added novel 

 contrivances for analytical chemistry, a field too recent to require 

 elucidation. 



[The paper was illustrated with 80 lantern views of the apparatus and 

 laboratories described, including also exterior and interior views of the 

 following institutions : Laboratories of the Museum in Paris, 

 of Strassburg University, Bonn University, College of New 

 Jersey, Kent Laboratory of Yale University, University of Michigan, 

 Lehigh University, Cornell University, College of the City of New York, 

 Woman's Medical College of the New Y'ork Infirmary, and School of 

 Mines, Columbia College.
