NEW SYSTEM OF PRESERVING MEAT.

(Morning Post, June 27.) YKMriinu, .it the Yictoiu Ducks, a nnmbei of guntlcintri assembled tv uitnuss some expeiinu'iits with a now lefngerating machine, the unention of Mi John Chamk;is, a iun-lii>!dei, (if Te M,\U, Xupier, New Zealand, mlio so f.ti bick as LSB2 took out lettt m pitent " foi iinpio\cmcnts in lefiigeiating and fietving, .uul in apparatus emplojed foi Midi pmpo-es." Hitherto tho inventors who h.ue worked m this duection h.i\ c based their procures on the utilisation of completed 01 cold air, bnt Mr UhatubeiV process consists in the condensation of the g»v> of .iiiiniiiin.i, and he claims tli.it his inadune may be woiked at onefnuitli the cost of any i-M-iting method. In Aitiruci the (/induction of coM has lonj? brcn hccurod by the evaporation of Mil.itilo liquids m \:icno and the condensation of tlieir \<>pour by the combined action of cooling watei and piessnrc ; so much *>o that the ninniifactiiie of ice by this jnocuss ih ciruud on by tho shores of the >« in th AineiuMii lakes, it luvhifr been found that ice could be ptoduced moio cheaplj' by artificial means thin by gatherin? and storapo of the natural piodiict. Hut it has lemained for Mr Chambers to show how the s.une fav->teni can be applied to the presuivation of dead meat. His apparatus is not a machine for pioducing lefngotating effecf, but one for applying the effect pioduced by annnonia, bulphuious auhydtide, ethei, and other similar substance^, to the cooling and diying of air, a feat which has not hitheito been successfully accomplished, so th.it an ordinary ammonia ico-niakmg machine with a " ChjuibiMs' cooler " attached may now be utilised foi the dual purpose of making ice for commcictal purposes and for freezing or pie«ct\itig meat. The machinery was diaplajed yesterday m full woiking order, and underneath the engine-room weie two chainbois into which the cold air was discharged. These, on being entered, were found to be of the temperature of lldeg. Falnenheit, or 21deg. below freezing point. As to cost, the mventoi states that the a\ernge consumption of coal per vojMgo thiough the Tropics would be one ton per 21 houis, and while the maximum cooling ■•fifed obtainable from the expenditure of lib of coal from air is 3.">7 thcnnal units, that obtainable, with the same consumption of coal, fiom annnonia by the compression system is 1428 thctnml units. The ex]icrimerits conducted at uhe Victon.i ]>ock.s yesteiJay seemed to afford gcueial satisfaction to the Luge number of persons niti'iesttd in the question who were a^ssmblod to w ltness them.

A scpi'l-kmknt to the London Gazette was issued on July 4th ontaining an Older in Council restraining the sale of pigs. The Older has been Usued in consequence of the dangcioua prevalence of swine fever in many districts. All accounti owing to the late firm of Jones and (in gory, ie Atvamutu, must be paid in by the 7th Inst.
