Twenty-seven Charolais weanling purebred bulls, fed concentrate ad libitum, were used to study puberal characteristics and early growth. Three calves were removed from the experiment for inability to protrude the penis and serve the artificial vagina.For the 24 bulls the average age at collection with artificial vagina of the first sperm and first motile sperm was 38 ± 1 and 39 ± 1 weeks, respectively. The first ejaculate meeting the minimum puberal criteria was obtained at a mean age of 41 ± 1 weeks. Body weight at puberty averaged 400 ± 13 kilograms. The ranges in age and body weight were 33 to 53 weeks and 266 to 499 kilograms. Semen characteristics and freezability of the first ejaculate were highly variable. First ejaculates for seven of the 24 bulls, however, satisfactorily withstood freezing and 3 weeks of storage in liquid nitrogen.Body weight at 365 days of age averaged 520 ± 10 kg (range 430 to 615 kg).

When necessity arises that makes a wide resection of the bladder peremptory, a large number of patients become solicitous as to what the function of the bladder will be after part of it has been removed. This solicitude arises so often that it is a striking feature, and it is because the urologist is assailed by this question that it has occurred to us that the function of the small bladder, or rather the regeneration of the bladder following resection, is important enough to merit consideration.The two lesions which most frequently require resections are carcinoma and elusive ulcer. If the lesions are treated by resection, it is imperative that the resection be very wide, and as a result a very small bladder is often left. This induces the frequent query on the part of the patient as to the ultimate outcome, from the point of view of the proper

This paper reviews investigations of the E-Sinteraction variable in verbal conditioning. The research is viewed in terms of the constructs of interpersonal attraction and interpersonal influence and is categorized under the headings: (a) experiments in which Es with different physical and personality characteristics are used; (b) experiments in which S's attraction to Eis manipulated by S's interaction with him (resultant interpersonal attraction); (c) experiments in which S's attraction to Eis manipulated by matching Es with Ss on the basis of psychological test scores; (d) experiments in which S's attraction to Eis manipulated by having a collaborator give Sinformation about E(induced interpersonal attraction). Major findings are summarized and suggestions for future research mentioned.
