well as part of the passages and 

 chambers before memioned. Be- 

 fore I conclude, I have to mention 

 that I caused a range of steps to 

 be built, from the upper part of 

 the perpendicular to the passage 

 below, for the accommodation of 

 visitors. 



" It maybe mentioned, that at 

 the time I excavated on the north 

 side of the pyramid, 1 caused the 

 ground to be removed to the east- 

 ward, between the pyramid and 

 the remaining portico which lies 

 nearly on a line with tlie pyramid 

 and the sphinx. I opened the 

 ground in several places, and, in 

 particular, at the base of the 

 pyramid; and in a few days I 

 came to the foundation and walls 

 of an extensive temple, which 

 stood before the pyramid at the 

 distance of only 40 feet. The 

 whole of this space is covered 

 with a fine platform, which no 

 doubt runs all round the pyramid. 

 The pavement of this temple, 

 where I uncovered it, consists of 

 fine blocks of calcareous stone, 

 some of which are beautifully cut 

 and in fine preservation. The 

 blocks of stone that form the 

 foundation are of an immense 

 size. 1 measured one of 21 feet 

 long, 10 feet high, and eight in 

 breadth) 120 tons weight each); 

 there are some others above 

 ground in the porticoes, which 

 measured 21 feet in length, but 

 not so broad nor so thick." 



Rules of Safety from Contagion, 

 and Regulations to Exterminate 

 Contagious Fevers. By John 

 Haygarth, M.D. F.li.S. a«(/

to what kind and degree of danger 

 other parts of the British domi- 

 nions are exposed from the Ty- 

 phous Fever which has spread so 

 fatally in Ireland, and in some 

 towns of England and Scotland. 



The typhous contagion remains 

 in the body in a latent state from 

 about the 10th to the 72nd day, 

 reckoning between the time of ex- 

 posure to the poison and the com- 

 mencement of the fever. This laio 

 of nature I discovered in 1781, 

 from observations on 72 cases. It 

 was fully coiifirtned by Dr. Ban- 

 croft in 1809, frojn observations on 

 99 cases. He observed that the 

 latent period of Typhus varied from 

 the 13th to the 6Slh day. Hence 

 it is manifest that an itfected per- 

 son may travel in pofect health, 

 from and to the remotest part of 

 Ireland and Britain. The in- 

 crease of fever in Liverpool, Glas- 

 gow, London, S^c. is thus clearly 

 explained. 



At this time of alarm and seri- 

 ous danger, I desire the favour of 

 you, Mr. Editor, to republish, 

 the following Rules of safety for 

 visitors of infectious families, and 

 Regulations to exterminate the 

 typhous fever. 



" At the requestof Sir Thomas 

 Bernard the Society for Bettering 

 the Condition of the Poor, gra- 

 tuitously circulated the following 

 Rules and Regulations to prevent 

 Infectious Fevers, extracted irom 

 a manuscript of Dr. Haygarth's 

 with his permission, which is since 

 published in a letter addressed to 

 Dr. Thomas Percival on the pre- 

 vention of infectious Fevers.
