Mix the ingredients in a capacious retort, and 

 distil as long as a dense liquid (which sinks in the 

 water with which it comes over) is produced.

TEIAL OF CAPTAIX GREEN AND MB. MATHEB. 



(Vol. vi., p. 342.) 



I would refer your correspondent, who seeks for 

 information as to this most curious and interesting 

 case, to the report of the trial (State Trials, 8vo. 

 edit., vol. xiv. p. 1 199.) ; the article on the Darien 

 expedition, and the trial of Captain Green, in Mr. 

 Burton's Criminal Trials in Scotland (1852, Svo., 

 vol. i. pp. 157 — 291.), which enters fully into the 

 particulars, and to the various publications at the 

 time, of which I have the following : 



1. ItemarJcs upon the Trial of Captain Thomas 

 Green and his Crew: London, 1705, folio, p. 16. 



2. The Last Speeches and Dying Words of 

 Captain Thomas Green, Commander of the Ship 

 Worcester, and of Captain John Madder, Chief 

 Mate of the said Ship, who was executed near Leith, 

 April 11, 1705, folio broadside. 



3. Observations on the Tryal of Captain Green, 

 and the Speech at his Death^ folio, p. 2. : London, 

 1705. 



4. The Innocency of Captain Green and his 

 Crew vindicated from the Murder of Captain 

 Drummond : London, 1705, folio broadside. 



5. A Scots Proclamation relating to the late 

 Execution of Captain Green: London, 1705, folio 

 broadside. 



6. An English Ointment for the Scotch Mange, 

 or a short Memorandum of the Scots' Cruelty to 

 Captain Thomas Green, Sfc: London, printed by 

 B. Bragg, N.D., folio, p. 2. 



7. An Elegy on the much-lamented Death of 

 Captain Thomas Green : London, 1705, folio 

 broadside. 



The following epitaph is subjoined to the elegy: 

 " Reader ! within this silent vault 



An English Captain lies, 

 By whose sad exit we are taught 

 That man of wealth who trusts a Scot 



Henceforth most surely dies. 

 A ship well freighted is a crime 



Here punished at a high rate. 

 And store of pelf at any time 

 At anchor near this hungry clime. 



Will make a saint a pirate." 



8. A Trip to Scotland, with a True Character 

 of the Country and People ; to which are added, 

 several Remarks on the late Barbarous Execution 

 of Captain Green, Mr. Madder, Mr. Simpson, and 

 several others, with an Elegy on their unmerited 

 Deaths : London, printed and sold by Malthus, 

 1705, fol. p. 13. 



Defoe, in his review (vol. ii. p. 90.), discusses the 

 case with great moderation and good sense ; and 

 appears to have been the author of the Observa- 

 tions on the Tryal (No. 3.), as the same views are 

 amplified and enforced in his peculiar style in 

 that publication. Jas. Ckossley. 



PUOTOGBAPHY APPLIED TO ARCHEOLOGY, ETC. 



(Vol. vi., p. 373.) 

 Dr. Diamond having now concluded his account 

 of the collodion process, and intending, as I un- 

 derstand you, obligingly to follow it up with 

 answers to such correspondents as may not have 

 perfectly understood his descriptions, will you 

 allow me to add to the few Queries I have already 

 submitted to you, two or three others suggested 

 by the paper of the 16th instant, so that the 

 Doctor, if he would be kind enough so to do, 

 might make a clean breast of It at once ? 



1 . After having produced an effective negative 

 by the use of the bichloride of mercury and hypo- 

 sulphite of soda, is the hyposulphite of soda to be 

 washed off? 



2. Is the silvered paper to be immersed In 

 (plunged into) the iodide of potassium, or only 



floated upon It ? 



3. Does Dr. Diamond " change the water and 

 repeat the soaking," as he says some others re- 

 commend ? 



4. After the application of the aceto-nitrate, is 

 the paper to be applied to the face of the collodion 

 picture wAz7e still wet? Will it not destroy the 

 negative, although varnished ? 



5. In the process of immersion in the solution 

 of muriate of ammonia, may several sheets be 

 placed in the same bath one upon the other ? 



6. When printing by the second or ammonlo- 

 nltrate process, there Is no yellow iodide to guide 

 the operator as to the time of immersion in the 

 hypo, necessary to fix the picture ; supposing the 

 picture to have attained quickly in the hypo, the 

 tint desired, is mere saturation of the paper suffi- 

 cient to fix the picture permanently, or is there 

 any other guide ? This is a very Important con - 

 sideration. L W. 



REPLIES TO QUERIES. 



1. Certainly, most thoroughly. 



2. Some operators prefer the one mode, some 

 the other. Dr. Diamond, after having performed 

 innumerable experiments on iodized p^ipers, is of 

 opinion that a more certain and more agreeable
