A Tubal Cyst in the Domestic Fowl
ber of our Association should feel his individual responsibility regardless whether he is serving as a Committee member. All of these Committees will be glad at any time to receive suggestions regarding work which they can properly carry on. Such co-operation by all of us will result in the accomplishment of great good for the industry and will insure an interesting and valuable Convention next summer.
THE RESULTS OF SINGLE, ONE-DAY MATINGS The purpose of the trials herein reported was to test the sexual strength for a one-day period of a vigorous male bird. The birds used were S. C. White Leghorns. The hens were sterile, and the male had not been with hens for fifteen days. The table gives the number of matings, the time of mating and the result:

A TUBAL CYST IN THE DOMESTIC FOWL.. While obstruction of the oviduct in the domestic fowl is fairly common, the resulting cyst in the present case was BO large as to merit a passing note. The hen from which the mass was taken was brought to the writer on October 26, 191V, by a student in the State University. This hen, a Yvhite Leghorn, was thought to be four years old. Up to the time when she was killed for cooking purposes she was perfectly healthy, and all of her other organ3, when examined, had the appearance of perfect health. Her appetite was good. Her owner stated that, for some time, a hen, probably this one, in his small nock had been occasionally laying, usually from the perch, a long slender, soft-shelled egg without yolk. The photograph shows the ovary, oviduct, etc., as they appeared when removed from the body; the six-inch rule gives an idea of dimensions. The ovary, O, consisted of a mass of small ova, all ol about the same size, 1-2 mm. diameter. The oviduct, D, seemed entirely closed between the ovary and the cloaca, C, and was enormously distended with the collected yolks to form the cyst, Y, which was over 15 cm in long axis by 8 cm in width, and weighed about 630 grams without the attached structures. The yolk in the cyst seemed to be in good condition, with no signs of p u r i fication. Whether this hen had ever laid normal eggs the owner could not tell, and he had no proof that she had laid the abnormal eggs mentioned above. ALBERT M. REESE, West Virginia University.

He mated with no female unless she were willing and never refused to mate when the invitation was given him. It will be noted that from 4:42 to 4:49 he made three matings, and we have no doubt he would have mated double that number of times had the hens been available. Of the 34 hens served by the male ten laid fertile eggs. One hen did not lay and 23 laid no fertile eggs. This result is what one of us (Anderson) expected to secure.

His hypothesis in making this experiment was that males will mate if opportunity is offered, so frequently that three will be little or no discharge of semen. Twenty-three minutes without fertility to ten matings followed by fertility would indicate that the male in this experiment discharged little or no semen in 23 out of 33 matings. It would appear from the result obtained that a cockerel in prime condition should not make more than eight or ten matings per day. The ten hens laid 28 fertile eggs and 73 infertile ones in the eighteen days occupied by the experiment. A less number of fertile eggs were produced than
