Boyse of Memorial Sloan-Kettering Cancer Center here. The Schering results are reported in the Dec. 14 issue of Nature. Using semen provided by 17 donors the ex- perimenters were able to increase the percentage of male-producing sperm from roughly 50 per cent to 85 per cent. Determination of this change was made possible by a new staining process that singles out the male- producing variety. The sex of the mammalian be it a man or a is determined by the nature of the sex chromosome carried by the sperm that fer- tilizes the egg within the female. Chromosomes are the bundles of tenetic material that become apparent during cell division. Each individual carries two sets of chromosomes within the nuclei of his body one set derived from each parent. The egg cells and sperm carry only one set so when a double set results. So far as the sex- determining chromosomes are the normal male carries one of the type from its and one of the type from its The female carries two of the type and can only produce egg cells with x-type sex chromosomes. The male. can generate sperm with either x-or y-type sex making for an almost equal production of male and female offspring. The German technique derives from earlier work in notably by A. M. Roberts at Guy's Hospital Medical School in London. Dr. Roberts pointed out last year that x-type sperm carry slightly more DNA yribonucleic than y-type sperm. Presumably this is because the x chromosome is slightly richer in that sub- which is the basic archive of genetic infor- mation. This makes the x-type sperm slightly heavier and 1 per cent fatter. on the it swims 0.15 per cent slower than the y- type sperm. Sperm are propelled by a whiplash or flagellum. Roberts showed when sperm were liberated at the top of a tube of seminal plasma which sperm had previously been the y sperm tend- ed to move down through the fluid more rapidly than the x sperm. This produced a region in the tube enriched in sperm. He noted that boy babies outnumber girl babies in a ratio of 106 to 100 and suggested that this might in part due to preferential progress of the lighter y sperm through the female reproductive KEEP BILLS DOWN OTTAWA Dry- cleaning bills can be reduced by proper care of says the Consumers' Associa- tion of Canada.

The Soviet system has allowed Estonians to maintain a distinctiveness in their but within certain limits that do not encroach on fundamentals. Most striking to visitors from abroad or from elsewhere in the Soviet Union are the towering spires of Tallinn's protestant the medieval gothic city hall rising from the cobbled streets of its old the steeply pitched roofs and turreted chimneys. Moreover. Estonian graphic and applied arts have more contemporary characteristics than most Soviet art. Tallinn favors a casual western style of entertain- ment and generally avoids the political billboards and slogans that are seen everywhere in Moscow.

And in the Russian community grew to 35 per cent by while the Estonian share of the city's population was down to 56 per cent. Estonian officials have reportedly advocated slower rates of economic growth and have fended off certain kinds of industrial expansion to avoid the necessity of attracting still more labor from Russia and other republics for new industry.

Neighboring yards for the most similar to devoid of beauty. An alleyway at the end of the yards meant anyone walking by could intrude at will. Thus Mr. Plummer's first job was to totally enclose the area with high privacy fen- cing. This both defined his property and took those in the yard out of public glare. Next he established flower beds around the edge of what he now termed his patio. He rais- ed these by means of an 18- inch retaining wall. TORONTO In high fashion clothes and in sports clothes.
