An open letter. WESTERN SPEECH serves a special junction when it records historical developments in Speech in the West. Therefore, we were especially glad to get this open letter written for the Oregon State Speech Conference, March 29, 1949.

摘要：
Phase-equilibrium data are presented for the system LiF-BeF2 and for the BeF2 end of the systems NaF-BeF2 and RbF-BeF2. The systems LiF-BeF2 and NaF-BeF2 are weakened models, respectively, of ZnO-SiO2 and CaO-SiO2 but with the notable difference that liquid immiscibility does not appear in the fluoride systems. The melting point of the cristobalite form of BeF2 has been determined as 543°± 5°C. and that of the willemite model (Li2BeF4) as 458 ± 5°C. Data obtained for the compound Na2LiBe2F7 show that its structure is very similar to that of the melilite hardystonite (Ca2ZnSi2O7).

摘要：
Pancreatic and gall bladder functions by means of secretin were studied in 9 patients with peptic ulcer and 7 patients with non-specific ulcerative colitis. In the peptic ulcer patients both pancreatic and gall bladder functions were essentially normal. In the patients with colitis the secretion of proteolytic enzymes by the pancreas was within normal range but a non-functioning gall bladder was found in 4 of the 7 cases. The significance of these findings in relation to the etiology of the diseases is discussed.

摘要：
The paths of electrons in a thin magnetic‐lens type of spectrometer are described by a non‐linear differential equation. The equation was numerically integrated to obtain a set of electron trajectories originating from a point source on the axis of the instrument. Trajectories for off‐axis sources were approximated. On the basis of these trajectories, the location and some properties of ring focus were studied. Theoretically calculated line shapes are compared for axial and ring focus. For reasonable values of resolution, the transmission of the spectrometer would be roughly doubled by performing the momentum discrimination by a ring focus baffle instead of by a small counter on the axis.
