.general, sur les resultats que I’on ohtient. en Europe de l’appli- 
cation faile de l’eleetriciie ä l’agrieultiire. M Morris fait d’abord 
connatlre les experienees tentees ä ce snjet ä diverses epoques par 
des hornmes de Science, tels que Maimbray, Nollet, Mntholon, 
I ägenhouss, Sir Mumphrv Davy, etc., et fait. rem'arqner la dif- 
ferenee d’opinion qui existe entie lc President de l’I nslitution 
royale et ie celebre Ber(juerei ; l’un etaidissaut que le pole nega- 
tit esi le pius favorable ä ia gcrmination et l’autre maintenant. au 
coutraire que c’est ie pole positif. M. Morris entre alorsdans les 
details suivants sur les experienees recemment failes par M. Porst er. 
a Mr. Fosler, acting lipon the result of experimerUs by Mr. Crosse of Jaunton, pro- 
ceeded to use, inslead of the fluid of the galvanic Ijoi tery , the free electiioüy of ihe 
a raosphere. Ue placed therefore (wo poles, each 11 feet high tipor. ihe frool lawn 
which h )d been recently laid down will] Chevalier barley and gross, aber diaining 
and subsoil-ploughing il. Over diese poles üxed doe INorih and Soulb of eacli other 
he stretched a piece of wire lixmg the lwo ends to stout wooden pins, driven in io 
theearih; ou tlie edge ol the plol, which was of 24 Euglish poles, and around the 
edges, which were straighl lines, he sank aboul two or ilnee iocbes beneato Ihe earth, 
lwo wires of eqnal leoglh die ends of which were fixed and in contact with ihe ends 
of ihe suspended wire. When (he barley upon (bis plol reached ihe height of six 
inches, it assumed a lively dark gieeo colonr aml grew f.tsier ihan the surrounding 
unelecliiüed barley plant. It mamtained iliis difference lo ihe last. The change of 
green lo yellow occurred later ihan in the rest of i he crop ; Ihe nnniber of Stocks also 
was grealer ; and each was larger when reaped. The ears from one grain of seed were 
snore nuoieious and longer, and the corn was larger and harder. 
« Oo being thrashed, weighed. and measured, the product from ibe twenty th ree 
poles (one pole of the twentv four being occopied wiih Victoria barley) was fonnd to 
be fifteen busheis; ihe bushel weighed 54 Ibs. (2 J / 4 bs. heyond ihe usual average) 
tlius giving 1 2 quarters or 104 busheis per acre. The weight of struw was 1,350 Ibs., 
equal to 9,390 Ibs per acre, bei i g iriple the usual average. 
« The cost of such an experiment for a qunrter of an acre would be for 6 Ibs. of 
wire for bnrying, 2/ 4 Ibs. of some for Suspension ’/< lwo poles of dry wood 1/ labour 
and 1/ total s / 4 as tlie area increases, the cost rapidly diminishes. » 
M. Morris li t alors ä la. Societf an Rapport de The Tring Elec- 
tro-Cullurai Association adoptant eniierement les vues et les idees 
de M. Purster ; il donne en meine ternps connaissance de plusieurs 
experienees faites avec plus ou moins de succes, et rapporte les ob- 
servalions recueillies par M. Sidney de Norfolk et communiquees 
ä 1’instituUon Royale ; il eite quelques passages du Memoire de M. 
Sidney, dans leqnel celui-ci fait connaitre les experienees qu’il a 
faites conjointement avec M. Soiley. 
M. Morris donne ensuite lecture äia Societe d’un article de M. 
Antiseil sur l’application de l’electricite a l’agriculture presente ä 
la Societe Royale de Dublin, et il en eile les passaiges suivants : 
e The effect of (he dislribution of electricity upon tlie air nigh the smfaee of the 
earth is remarkable. It has been asceriamed ihat the almospherical electriciiy is of 
a positive character, (*) wtiile that of ihe earlh is negative; and any body serving as 
a point of discharge lor these two kinds, receives a shock which, in the case of a 
plant or tree growing, would be a Stimulus lo its growth if ihe shock were gemle, 
wbile il would be fatal to its vitalily if it were as severe as in ihmiderslorurs. So
