ellaewhich forms the inner side of Wards triangle. Regarding the femur as a weight-carrying structure this line of experi-mental fracture indicates its weakest part. It will of course be noticedthat these fractures produced experimentally do not correspond with an\^ordinary fractures occurring during life. The strength of the normal boneis shown to be vastly more than sufficient to support any vertical compres-sion to which it can be subjected in the living body. The experiments show that in the normal femur placed in its properposition and subjected to vertical compression, experimental fracture resultswhen the shearing strength of the bone is reached, and before the bendingmoment can be made to produce a fracture. Further, the shear takes placein the plane which X-ray pictures show to be occupied by least bonematerial. The disposition of the tension lamellae at the upper, or basal,side of Wards triangle is such as to resist shearing rather than bending. and Pliysiolvgy, April 1910.)

THE PITUITARY FOSSA AND CERTAIN SKULL MEASURE-MENTS. By D. P. Fitzgerald, B.A., M.B., R.U.I., Professor ofAnatomy, University College, Cork. The pituitary gland being one of those organs about whose functionpractically nothing is known, it seems strange that very few attempts havehitherto been made to clear up some of its mystery or to endeavour toestablish any possible co-relation between it and the size of the skull. Inthis short paper I projiose to deal with a feature of the gland not hitherto,as far as I am aware, dealt with, hoping that it will stimulate furtherinvestigations in this particular direction, and thus, perhaps, contributesome aid to the physiologist in his dealing with the subject. My investiga-tions were undertaken for two objects, viz. (1) to ascertain if any co-relation existed between the size of the pituitary fossa and certain skullmeasurements; and (2) to study the ver) varying shapes of the fossaitself, as determined by a series of casts.
