Prevention and Protection from Pleuro
 Pneumonia.

GDlIOh OAIAZkN-Dcar SIT. In rel erenoe to the sdvissbility of the inocula- tion of cattle by our stockmen ss a pre- servative from the contagious pleuro- pneumonia of cattle. desire to observe that whilst that is & remedy, or prophy- lsctIc, to be used in an emergency, vet 1t should not be forgotten, that inocuiat- ed animals can themselves communists the disease to healthy animals, and ID oculation is only the substitution of a lesser evil, for one capable of slmos. in- finite magnitude. If allowed free course.
 Primarily, the first thing to do is, if possible to stamp out the disease Tn its incipiency, by the destruction and ere nation of all animals infected and of all infected surroundings such as stables, corrals etc., and the non usage, for a sufficient length If time of range or pas tursge where iDts cted animals have grszed, together with the quarantine and iso!stion for proper period of all suspected animals, for prevention is better than cure," even if cure were pos sible which at present it IS not.
 What we essentially need. as also al ready correctly suggested by the CITIZEN itself, IS Rn improvement on Inoculation, by the substitution of Jme form of va clnatlon.
 Such vaccination should not only be less virulent iu its action on the 8 stem, but above all non-contsgIoUs; l may bereafter, if acceptable, offer some fur ther remarks and suggt stIons; but Will | only remark now, that for instance m | the fatal disees of charbOn m cattle and sheep Dr. Salmon nss very clearly shown that 1t can be stamped out of tiOcks and herds, and ss absolute protection there | from afforded Rs from small pox ID hu- manity. the inoculstioD or vacInstion with cultivated virus, deprived Of its original virulence, yet sufficiently yirIle for protection.
 | In like manner 1 think there can bs little question, but that iudicious exIer- iments can and will produce virus that can be substituted for contagious IT, oculstion In pleu'O pneumonia In this view of the matter. the following extract from the report of Dr. Salmon to the Agricultural Department In 1882. IS very Il eug Etlve. II reads mus.
 At the recent annual reunion of tn | five acsdemlts Of the InssItute, NJ. Bon- | ley was selected by the Academy of | Sciences 10 delIver the address from that body. Speaking ID reference to the contagious diseases of animals and of Pasteur's investigations, bs sad: Yes. this great mystery of contsgIOn that the efforts of nv, stIg stors in the times pre- ceding ours remained powerless tn dis cover, s fence has just definitely reveal ed, and has given complete satisfaction, on this point. ID that which Is the su- preme aspiration of mRn: The knowl- edge of causes.
 It is from this great fact, the discovery of the role of the infinitely small If the invisible world in the development of contagious diseases, or, to speak more vigorously, in a certain number of these diseases for which the demonstration Is complete-It IS from tlis great fact that thls other dis 'ov-ry, much greater still, proceeds. that of the trsu s,Ormation un- der the direction of man of the agent by which they kIll into an agent truly pro- tectIve, since its influence, now beneti- cial, has for effect, like the vaccine of Jenner, to invest the organism which has .eceived IL wIth s complete immuni- ty against the attacks of the fatal dIs- ease.
 This is not sll, and here we touch upon the great discovery winch will be the glory os medicine 10 thIs century and in all times; this mIcrobe of conts- zion which We have got hold of, which We have been able to reproduce by the srtifice of its cultivation ID appropriate n. a .l always with its fatal activity, this microbe 'nt tet- '-'rnl-rce ss,rs 't i5ls p5esi5le e.; s | courting certain determined influences ! to get upon it-of which the experiment | ter is master and that be directs at hIs wilt IS possible to deprive It of the excess Of its energy and to make of 1t, | after having leeReDed its power ID the necesssry degree, no longer tbe agent of | death but that of preservation ID s word | to transform It into vaccine. And when | it has experIenced this transformation by the best instituted ard most iDgeu- iously conceived of artifioes, IL IS possi- ble to make 1t the source of mIcobes at l tenuated like itself, and with which the attenuation has become a specific | character.
 And these varieties, degenersted from their original power and become benefi- cent even by their feebleness, IL Is possl- ble to reuder indefinitely productive, to seal the product ID hermetic vessels,
 which. distributed wherever contagiOn
 menRces. may serve everywhere by i.-
 oculatior to protect the susceptible
 species yf animals from contracting this | cOntsglOn.
 Ina word, by the command of scIence
 the microbe which prOducesideath has
 become 6 vaccine preserving from its attacks. This is the great discovery | Vey great, in fact; for what causes its greatness is not alone the results already
 attained; 1t is also the method from which it proceeds, which Is susceptible of being generslized, an2 which, from the results already obtained, authorizes every hope m its fecnndIty.
 Now, alt sough these remarks by Pro | lessor Bouley, were not made with a view to any special reference to conta- | gious Pleuro Pneumonia, yet their sp- | plication is very obvious and 1t is equally evident that the scientific and thorough investigation of this subject IS one of national importance, Rs well ss one Of sufficient local gravity m places as to make state or territory investigations and experiments, as well as the cafe guards of quarantine and other regula- | tions matters for proper Legislative con siderstiop.
