 as determined by tlie photometer, with less gas. 



Mr. Tineili, formerly U. S. Consul in Portugal, introduced Mr. 

 Marzoni, of Lago Maggiore of Italy, the patentee of machinery 

 for converting entire blocks of suitable wood into a pulp for paper 

 making. Mr. Tineili exhibited several conditions of tho pulp, 

 and several different samples of paper made from it. Some ten 

 to twenty per cent of rags are added to the pulp. The pulp can 

 be supplied for one cent per pound weight, 



Mr. Pell read the following paper on the subject of Light: 

 •Gas is, in my opinion, far superior to anj^ other material as an 

 agent for giving light in dwelling houses and public buildings, 

 for the reason that it is safe, cheap and an €conomiser of time. 

 It may be lighted and extinguished in an instant, without emit- 

 ting sparks to set Are t-o clothes, as often occurs when lamps or 

 candles are used. Its odor, being entirely unlike that emitted 

 by any other burning matter, constitutes a very valuable property, 

 inasmuch as the source can be detected and at once prevented, 

 the odor of gas is certainly disagreeable, but it is not of common 

 occurrence in our houses or churches, and is as unnecessary as 

 that cess pools or drains should be choked, or left uncovered. 

 When the odor of gas is perceived, do not on any consideration 

 enter the room wath a lighted taper before the windows and doors 

 are thrown open for a short period of time, that the gas may 

 have an opportunity of escaping. 



All those who have used gas will allow that a building thorough- 

 ly lighted wdth it possesses comforts and enjoyments positively 

 unknown to those necessitated to use lamps or candles, Avhich 

 give an indifferent light. Gas, to be agreeable, must not be used 

 in such excessive quantities as it usually is, there is a medium in 

 all things, which should be observed; if you go beyond that 

 necessary for all and every practical purpose, you do your eyes 

 an injury, commit waste, destroy the oxygen, and overheat your 

 apartments, all without reference to utility or comfort. If for 

 special purposes it becomes necessary to light a house brilliantly, 

 gas only can be used, as any other light would inevitably give 

 dissatisfaction. If obtained from wood it will be cheap, provided
