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 aman 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,
