The article features Mill Valley, a secluded suburb of San Francisco in California which is considered as the American commuter's dream. Postmen have known to get lost in the middle of the town. Many of the suburb's early houses were built as weekend retreats and did not become full-time houses until the earthquake that occurred in San Francisco in 1906. An angular, rustic-and-modern structure which surrounds a stand of redwoods is one of the current attractions in the town. It describes the environment and climate in the town.

Focuses on the development of camping equipment designed specially for women in the U.S. in 1958. Implications of the release of camping equipment in bright colors; Advantages of the development of a disposable paper tent; Features of the station wagon designed by Bill Moss of Ford.

1.1. The bromine method of Chattaway11for the determination of histidine in urine has been modified so that interference of urea is avoided and the estimation of totalhistidine is satisfactory.2.2. The creatinine: histidine ratio has been determined in the urine of a large number of pregnant and nonpregnant women and of men.3.3. Eighty-eight per cent of the pregnancy urines (169) examined showed low ratios, while only 9 per cent of the urines of nonpregnant women (59) and of men (50) had ratios as low as 1.70. There was no detectable difference in the ratios of nonpregnant women and men.4.4. The increased excretions of urinary histidine, as evidenced by low creatinine: histidine ratios of the urine, were not found before the third month of pregnancy and cannot, therefore, be used as an aid in the early diagnosis of pregnancy.

When the crop of Aplysia is bathed by a solution containing 0.011 M KC1, tonic contraction and inhibition of the rhythmic movements result if potassium is either withdrawn or added in excess. The action of potassium on tone in the Aplysia crop is independent of the calcium concentration. Rb, Cs and NH4 act like potassium on the Aplysia crop, but Li does not. Rb is about twice as active, Cs about one-half as active, and NH4 about one-fifth as active as potassium. The changes of tone seen in the Helix crop when the potassium concentration is varied are identical with those seen in vertebrate plain muscle under like conditions. Addition of a little potassium to the heart of Maia perfused with a potassium-free fluid causes a drop of tone. High concentrations of potassium have two opposed effects, a contracting action and a secondary depressing action. The action of potassium on the striped muscle of the Maia heart is essentially like its action on molluscan or vertebrate plain muscle.

Periarteritis nodosa is a rare, grave disease remarkable for its protean manifestations. Although it was first described as a clinical entity by Kussmaul and Maier in 1866, only 50 of 350 cases recorded by 1940 were diagnosed prior to death.1 Sufficient cases have been recognized antemortem during the last 15 years to attract widespread interest in the clinical manifestations as well as in pathogenetic and therapeutic problems of the disorder. Increased recognition may be largely due to awareness of the disease entity, coupled with a more ready resort to biopsy, but some absolute increase may have occurred in relationship with the increased use of such drugs as the sulfonamides; and there may be cases that formerly would have succumbed which, with modern drugs, have survived to show widespread vascular damage. It should also be realized that the scope of the term ``periarteritis nodosa'' has been greatly
