I regret to be unable -to learn the proportion of the competitors who were farmers, butchers, or non-experts. It would be well in future competitions to have a line on the cards for ` occupation." Certainly many non-experts competed, like those clerks and others who have no expert knowledge of horses, but who bet on races, guided by newspapers, friends, and their own fancies. FRANCIS GALTON. Ketene. WHILE engaged in a research on the pciymerisation of unsaturated compounds, we were led to try the action of a strongly heated platinum wire on various organic sub-' stances. It is unnecessary at this stage to discuss our general results, and we will therefore deal at once with the action of the wire on acetic anhydride. This substance when treated with the hot wire yielded a compound boiling about -65 and freezing about -130, which on standing at ordinary temperatures condensed fairly rapidly, yielding a brownish-yellow oil which, like the gas, has an extremely pungent smell. We have not yet succeeded in obtaining the new body in a completely pure state, but as our work has been interrupted for some time, we venture to give the following preliminary data. On exploding one volume of the gas with excess of oxygen, there was a contraction of io1 volumes, and i85 volumes of carbon dioxide were formed, while t.86 volumes of oxygen had disappeared. The corresponding numbers for the reaction CH,: CO+20,=2CO2+H,O are I:1:2:2. Another sample ' gave a density of 3qq (H,=2), while that calculated for CH, : CO is 42. This sample was, however, far from pure. The gas is absorbed by- all the ordinary reagents, including water. It.combines with bromine, and appears to give a crystalline compound with bisulphites. It chars when treated with phosphorus pentoxide or concentrated sulphuric acid. These two reagents themselves produce traces of the gas when they are allowed to act on acetic anhydride. We would add that we have also obtained the substance from acetone, and it seems probable that it can be obtained by our method from all substances containing the group -CH,-CO-. We would suggest that the body is the parent substance of Staudinger's ketenes. We hope to be able to publish a fuller communication shortly.. N. T. M. R ILSMORE. A. W. STEW.1RT.

T HE most recent report issued from the United States Bureau - of Education at Washington gives detailed information respecting recent developments of the various grades of education in the States down to June 30, 1904, and in it the Commissioner of Education . gives a prominent place to the work of universities and colleges. The statistics now provided make it possible to supplement the article published in these columns (vol. lxviii., p. 25). dealing with university education in the United States, and to give some indication of the progress which has been made in -American institutions. of higher education during recent years. NO. 1952, vnl , ^51 There has been, in the first place, a large increase in the number of students attending universities and colleges in the United States. Whereas in the Year 1899-19oo the total number of men students was, roughly, 6t,8oo, and of women students 25i3at1, tha, numbers in 1903-4 had become, for men, r=1-472,o00, and for women nearly 31,000. The number of professors and instructors has in. creased in a similar manner. In 1899-i9oo the number of such teachers in institutions for men and' for both sexes was 12,664 men and 1816 women; in 1903-4 these numbers had become 13,342 men and 2272 women. In institutions for women alone the increase is not so decided. The number of men teach, ing in these institutions was in the former year 697, and in 1903-4 only 631. The number of women, however, shows a marked increase from 1744 to It is interesting and instructive, too, to study the rise and fall in the popularity of the various subjects taken up by students. At the two periods under comparison there were some remarkable differences. In 1899-1900 the number of students studying classics and other subjects of general culture (as the report calls it) was roughly 57,000, but in 1903-4 the number had reached 65,000. In the earlier year the number of students in classes of pure or applied science was well on towards 26,doo ; in 19o3-4 this number had increased to 32,ooo. The relative popularities of humanistic and practical studies may be said to have undergone little change at institutions of the rank under consideration. But in this connection it must be remembered that at.- the great technological institutions, which are not- included in these statistics, large numbers of men are engaged entirely in studying branches off applied science. The total value of property possessed by the institutions for higher education in the United States amounted in 1899-1900 to about 72,120,0001., and in 1963-4 this large sum had increased to 93,043, - The endowment funds in the former year were valued at 33,240,0001., while in the latter year this provision for future contingencies had grown to 41,313,0001. The value of gifts and bequests received by institiltions for higher education during 1899-1900 was 2399,0001. ; in IQ03-4 the amount had increased to 2, 7 40,0001. ; and Last year as 'much as 5;ono,oool. was raised in this way. Twenty-five institutions in the former year received from private donors gifts of as - much as 20,0001., and in 1903--4 as many as twentynine institutions were equally fortunate. For the first of the years with which wre are concerned in this comparison, the total income, excluding benefactions, amounted to 5,7T2,0001., of which about 2,234,0001. was received in the form of tuition and other fees. In 1903-4 the total income had reached 8,o66,oool. In connection with this sum, the Commissioner for Education remarks :-" It is a wellknown fact that the income derived from fees received i from students forms only about one-third of the total income, the remainder necessary to meet the expenses of the institutions being derived from endowment funds, State aid, and miscellaneous sources." In 1903-4 the State and municipal aid to higher education amounted to 1,984,6001., as compared with 893,ooo1. in 1899-19oo. It is thus seen that the striking disparity between public and private efforts-in behalf of higher education in the United States and Great Britain, pointed out in the article to which reference has already been made, has, in the interval of four years with which we are here dealing, becomee more accentuated; and, instead of having made up leeway, we appear to have fallen even further behind.
