the above heading by Lieut. Murison, I.M.S., in the September number of the Indian Medical Gazette occurred amongst the officers of the Somaliland Field Force during the recent expedition. They invariably began over the metacarpophalangeal joints as a small vesicle and were generally ascribed by the patient to a scratch from a thorn. In one case there were symmetrical sores over the metacarpo-p...

Under the harsh environmental conditions present in severely overgrazed, semiarid rangelands, facilitator plants offer a promising tool for ecological restoration. This study investigated facilitative effects of Aloe secundiflora—a native drought-tolerant, unpalatable, thorny shrub—on grass establishment in degraded rangelands in Kenya. We planted native perennial grass seeds adjacent to three ...

As early as 1914 Schwarz (1) suspected an inverse relationship between adrenal activity and the level of circulating eosinophils. Twenty-five years later Dalton and Selye (2) noted eosinopenia following stress in animals and related it to release of adrenal cortical hormones. More recently Thorn and his associates (3, 4) observed a prompt decrease in circulating eosinophils in healthy persons, ...

Tree cover in savanna ecosystems is usually regarded as unstable, varying with rainfall, fire, and herbivory. In sub-Saharan Africa, elephants (Loxodonta africana) suppress tree cover, thereby maintaining landscape heterogeneity by promoting tree-grass coexistence. In the absence of elephants, tree encroachment may convert savannas into closed-canopy woodlands; when elephants increase in abunda...

We investigate the following problems. Given a spherical fibration, does the Whitehead square of its homotopy Thom class vanish? If so, is the homotopy Thorn class a cyclic homotopy class?
