The sulf.ric acid leaching kinetics of.South Af.ican chromite was investigated. The negative inf.uence of.a solid product layer constituted of.a silicon-rich phase and chromium-rich sulf.te was eliminated by crushing the chromite and by selecting proper leaching con- ditions. The dimensionless change in specif.c surf.ce area and the conversion rate of.the chromite were observed to exhibit a proportional re- lationship. A modif.ed shrinking particle model was developed to account f.r the change in reactive surf.ce area, and the model was f.tted to experimental data. The resulting model was observed to describe experimental f.ndings very well. Kinetics analysis revealed that the leach- ing process is controlled by a chemical reaction under the employed experimental conditions and the activation energy of.the reaction is 48 ***-1.

This article compares two Latin poem dedications which may contain hidden sub-meanings and possible displays of.a basic puzzle method called acrostics, each dedicated to the same nobleman. The Latin verse in 1579 by Anthony Munday f.llows acrostic English poems and may ref.r to his patron as ＂a lover of.Pallas Athena＂（the Spear-shaker of.Greek mythology）. The Latin verse in Robert Greene＇s 1584 book may contain a Latin acrostic and appears to identif. Cupid, the ＂winged Love,＂ as a companion of.the same patron as Munday＇s f.om f.ve years earlier. That Cupid trope appears similar to ＂the little love god＂ allusions to Cupid in several of.Shakespeare＇s sonnets （e.g., #s 153 and 154）. More than these discussions, this article explores dif.iculties of.translating f.om Latin into English, or vice versa, and the pitf.lls which can occur.

Hypothetical Earlier Dating f.r The Passionate Pilgrim and f.rst f.lio

Did part or all of.Shakespeare＇s The Passionate Pilgrim （TPP） actually predate 1593 Venus ＆ Adonis （V＆A） and 1594 Rape of.uereee （Rof.）？ Oddly enough, that may be the case, because the sole extant copy of.its f.rst edition has no title page, thus no date. Copies of.its second edition do have a title page and are clearly dated 1599, plus a 1612 augmented project was marked ＂third edition＂. Thus, it should be signif.cant that some of.TPP＇s poetry have been f.und in manuscript or early publications back to the early 1590s, and in one case perhaps as early as 1585. But TPP may be a relic of.a much larger anthology of.poetry which possibly existed in manuscript circa 1589-94, was revised circa 1610-12 to accompany an intended publication of.all of.Shakespeare＇s works （poetry and drama）, but was not f.lly published until nearly three decades later. It is also notable that the 1640 anthology attributed to Shakespeare contained TPP plus lengthy poetic paraphrases f.om Ovid in much the same mold as V＆A and Rof.. Moreover, the 1640 anthology may hold a key to radically earlier dating of.the 1623 f.rst f.lio （f.）. We will brief.y delve into the murky world of.the Elizabethan publishing world of.the 1580s and beyond, wherein the 17th Earl of.Oxf.rd＇s f.rmer servant, Anthony Munday, may have had an important role in the disposition of.each ＂Shake-speare＂ work.
