 gas '"^"'"If/"'""" .„„., :. which the tube had been laid. Many kinds

!,"T 'h:\ aTcon iced thafmoi-e than 5 per cent, should be allowed 

 tv\he leakage of the raaii alone, independent of all those other sources

 le mete registered with mathematical accuracy the quantity of gas 

 ass n' >hrou4, them ; but he was of opinion, that if the water line of the 

 vet meter was correctly maintained, ihat meter, in ,ts actual improved 

 Tt^fe was.he most accurate. In very hot, -,. -^^ - ^^ ^'^.f ™:;f;j 

 i^Piers were essential, as the evaporation of the watei.or ii>, tieezin , 

 wo dd equalh Xange'its action. The freezing could be obviated by dis- 

 Tol ngTtlie wa.erl little common sal. or some --stic potash (soapers 

 leesV but the evaporation could not be prevented. He I. .ought, that 

 when in "cod order, the dry meters would work under as light a pressure 

 Ts the we° meterT but there was a possibility of the leather becoming 

 rig S if"hey ema ned any length of time inactive. The ratio of the amount 

 f the leakaVe did not appear to follow the same rule, with respec to the 

 llreteroffhe pipe, a's'did the quantity of gas passing along pipes of 

 nivpn (Hfliiipters under given pressures. ....

 position assumed in the paper. The case of the «"' 'f^^^^;™ „^Vner

 Reached Birmingham, wh'ich was at about 120 feet 'j^'^er level than he

 traction occurred, no alteration could take place in the quantily ot gas 

 exp Ikd by each'forward motion of the disc; for the packing formed a

Peps.cs -We learn from the MorgenblM that Persius, the German 

 archi.eC, died lately-some time we conjeciure about last June, for no 

 DOS ive date is <.iven-shortly after his return from a visit to Italy. As to 

 his a.e i t s merely said that he was " in the prime of life ;" nor have we 

 a yit b en abeL gather any particulars respecting him from other 

 sources for on turning to Nagler's '■ Kunstler Lexicon," where we fully

 that he is not so much as mentioned al all by tba remarkably " '«d"s"-'°"^
