Mr. John Newlano, oF the Inner 

 Temple, is preparing a Treatife on Con- 

 trails, as far as they fall within the jurif- 

 diflion of a court of equity. 



The fifth volume of the Supplement to 

 Mr. Viner's Abridgment is Jireparing 

 for publication. 



Mr. W. D. Evans has in the prefs A 

 Tranflation of Pothier's Treatife on 

 Obligations; with Illuftrations adapted 

 to (heEnglifh Law. 



Dr. Griffiths, author of a volume 

 of Travels, is engaged on a tranflation 

 of Lenoir's French Monuments, which 

 will extend to about fix volumes oftavo. 



Mrs. Jackson, widow of J. Jack- 

 son, Efq. Advocate General of Jamaica, 

 has in the prefs Dialogues on the Doc- 

 trines and Duties of Chriftianity. 



A Board of Health has lately been 

 eftabiifhed for the purpofe of preparing 

 and digeftlng regulationi for the molt 

 fpfedy and efFeC\ual modes of guarding 

 againrt the introduftion and fprcading of 

 infection, and for purifying any fliip pr 

 houfe in cafe any con'agious diforder 

 (hould manifeft itfelf in any part of the 

 United Kingdom. This Board Js to hold 

 its meetings at Somerfet-Piace, and it is 

 compoftd of Sir Andrew Snape Ham- 

 mond, Sir Lucas Pepys, Dr. Reynolds, 

 Sir Francis Milman, Dr. Hunter, Dr. 

 Heberden, Sir Alexander Monro, and Dr. 

 Harnef*. 



Mr. Nicholson and others have been 

 inveftigating the caufe of the noife in wa- 

 ter juft before it boils, which is ufuaily 

 cMtAJimmering \ and, from fome experi- 

 ments, it fcems to be occafioned by the 

 condenfation of (learn bubbles, in their 

 aicent through the cold fluid above. 



Mr. Stodart gives the following as 

 a good method of gilding upon fteel : — 

 To a faturated folution of gold in nitro- 

 muriatic acid, add about three times the 

 quantity of pure Culphuric ether, and agi- 

 tate them together for a fhort tinV. The 

 gold will foon be taken up by the ether in 

 the form of nitro-muriate of" gold, leav- 

 ing the remaining acid colourlefs at the 

 bottom of the veltel, which muft be drawn 

 off by means of a ftop cock. The acid 

 being difcharged, the inftrument to be 

 gilt, having been previoiifly well poliflied 

 and wiped clean, is to be dipped for an 

 Inliant into the ethereal folution, and on 

 wiehdrawing it, as inftantly wafhed by 

 agitation in clear water, to get rid of a 

 finall portion of acid necefl'^rily taken up 

 with the metal. If this be neatly done, 

 the fuiface of the fteel will be compltte- 

 ly and very bcautifiiliy covcied with 

 gold. 



The travels undertaken by MefTrs. 

 Alexander von Humboldt and 

 AiME BoNPLAND, into the interior of 

 Amet ica excite general intereft. In fail, 

 there are few countries fo worthy of the 

 attention and inveOigation of enlightened 

 men, and few travellers have combined 

 with thefpirit of obfervation, and the nu- 

 merous attainments and talents poflefled 

 by Meffrs. VON HOMBOLDT and BoN- 

 PLAND, fuch ardour for the improvement 

 of the fciences, fuch courage and .'ucccfs 

 in the execution of the plan they had 

 formed. MefTrs. LevraUlt, Scholl, 

 and Co. have publillied a Profpeilus of 

 the Travels of thefe gentlemen, the pub- 

 lication of which has been committed to 

 them by the authors. Travellers, fsy 

 they, have, in general, introduced all their 

 obfervations into the body of their works. 

 M. VON Humboldt has, however, 

 thought proper to , follow a contrary me- 

 thod, and to treat fcparately of oUjefls 

 which arc of a different nature. He is, 

 therefore, determined firft to give to the 

 public detached colleilions containing 

 whatever relates more particularly to aftro- 

 nomy, geology, botany, zoology, Sec. be- 

 fore he pubiifhes what may properly be 

 denominated his Travels, which will em- 

 brace every thing conneiled with general 

 phyfics, the origin of nations, their man- 

 ners, their civilization, prol'perity, anti- 

 quities, commerce, and political ecoiicmy. 

 Of this portion of his obfervations, and 

 the Hiltory of his Travels, he will at pre- 

 fent publifli only an abridged account, en-> 

 titled Abridged Relation of Travels be- 

 tween the Tropics, performed in the In-^. 

 terior of the new Continent, in the Years 

 1799, 1800, 1801, i8o£, and igo']. 

 MelTrs. Humboldt and Bonplanu, 

 continue thepublifliers, being united by 

 the ties of the moft intimate friendftiip, 

 having (ha red all the tatigufs and all the 

 dangers of this expedition, have agreed 

 that all their publications fhall bear their 

 names conjointly. The preface of ^ach 

 work will announce to which of the two 

 each diftinil part belongs. This arrange- 

 ment will accelerate the enjoyment of the 

 public, and will facilitate to a greater 

 number the means of acquiring what wi'I 

 demand a lefs advance at a time. Belldes, 

 it is nnt agreeable to be interrupted in 

 the midft of a nairative, fometifoes hy< 

 the details of an aftronomical obftrvationj 

 and at otheis by the delcriptionof a plant 

 or -AW unknown animal. He Willpuldifh, 

 at the fame ti^^e, his agronomical cbier-
