SCIENCE AND ART.

In the new Werdcrman electric lamp there i is no globe from which the air has beem ex- ] hausted as in all other incandescent systems. Instead of a filament of carbon M. Werder- 1 man uses silicium, with, it is claimed, better i results. s "Tripolite" isthenamegiventoanew build- ( jnc materia! which is intended to be a substitute for Hue, cement and plaster under certain j circumstances. It is composed of sulphate 1 of lime, coke and oxide of iron in some form ( or other. ; For last year the world's production of lead is estimated by Jlerr Landsberg at ; 440,000 tons. China and Japan are not iu- s eluded as producers of this metal, although i the probability is that their output of lead is i very large every year. When it is necessary to bring up a child ' on cons' or nurses' milk, it has been proved preferable to use the rr.ilk of a cow, unless tho nurse is well fed and kept from doing hard work. Human milk is quickly i mpoverished by severe mental or physical labour. Daring his late investigation of the distribution of heat in the obscure region of t.'c- solar spectrum, M. P. Desaius obtained which enables him to construct the curves which represent the distribution of heat in the dark spectrum, and he promises soon to publish some valuable comparative results. A party of nearly eighty artists from Belgium has invaded England. They include artists of many kinds, architects, sculptors, painters, and archaeologists, and aro accompanied by several ecclesiastical personages. , They arc members of a guild having for its i object the study of Christian art, and visit , I England in order to see and study the glo- • ' lious churches and cathedrals of the country. A French wmil, M. Kegnard, has been . lately trying tho etlect of a "blood diet" on lambs. Three lambs which had been aban- . doned by thuir mothers were fed on " pow- . tlurcd blood" with thu most gratifying results. The lambs increased in size and attained un- , usual proportions for their age. The coats of wool also became doubled iu their thickness. , Encouraged by his success with the lambs, M. Reguard is now feeding some calves on L blood. ; The Postmaster-General has decided to ; grant licenses to different companies to estab- ' Wish telephonic exchanges throughout Great • Britain. This license does not confer special ! power to erect poles and wires on or under public or private property, but licensees will . have to make their own arrangements with : local authorities, or with people whose pro- [ perty has to be passed through. The.-.: can ; be no doubt this decision will give a vigorous > spurt to tho more general employment of the : telephone. , A museum of great importance for ethno- : graphical science is being formed, or rather .' being re-organised at Koine, in the famous i I'apTl Propaganda Fidei, which is now under '• the intelligent direction of Cardinal Simeoni, 1 tho former Secretary of State. No scientific > institution i" the world has such extended b connection with the barbarous and senilis barbarous populations of all the Continents i as the great Komsn Catholic Missionary r' College can boast, in which priests of all ,' races aud coluui-3 are trained for their ,vork. - One of Cardinal Simeoni's predecessors iu , oilice, Cardinal Borgia, made an extensive - collection of the various reticles sent to the 1 Propaga.ua by missionaries. The collection has been little known outside the College it- . self, though it has long born the ambitious t title of the Museo Borgia, The present head h of the institution has recognised the immense t value of this collection to ethnographical is 'study, and as it is constantly growing in size n and in variety of materials, he has determined ', to iiarange it upon a scientific plan, so as to 1 make it useful as well as interestiiir,'. It is to be re-arranged in departments, allotted to y natural history, geology, domestic utensils, weapons, ind other sections.
