The account of his voyage to Chili , and likewise that of his journey to Chanarcillo show great power of observation on a tedious voyage , to which many men of active minds succumb ; and it is marked as well by considerable humour as by the application of much scientific knowledge . It was not , however , intended for publication . These contain but a small portion of his labours , as he has left in manuscript an immense bulk of work ready for publication , the principal of which

are—1 . Tables of hardness , specific gravity , general and chemical eharaetci of all minerals , alphabetically arranged , with the authorities . 2 . Tables of temperature , the boiling and fusing points of all known substances , tbcrmomctrically arranged . 3 . Tables of the solubility of all inorganic substances , 4 . Tables of the solubility of most organic substances . 5 . Tables of the specific gravity of all known substances .

6 . Tables of all known organic substances , alphabetically arranged . He was a most assiduous contributor to numerous chemical and other scientific journals of the day , and was ready to increase not only the domain of science , but the public acquaintance with its resources . He was initiated in the . Royal Sussex Lodge ' at Bristol , No . 986 , in July , 18-53 ; this is the Lodge of which his brother is now Worship ful

Master . As will be seen , his Masouic career was brief ; ho shortly embarked for South America , where it is deeply to be regretted no Lodge was available to him , for no endeavours have been made of late years to make the lights of Masonry available to that country , although there are many Masons scattered about . The death of our brother on the wide ocean , after a long absence , did not mark his loss so impressively as would have been the cast ? if such a melancholy event had occurred during his residence among us . It is to this reason , we must attribute the circumstance that no

commemoration , so far as we know , lias been made by the Boyal Sussex Lodge of this distinguished member . This is one reason for oui publishing this brief and imperfect memoir , not with the view of supplying tho deficiency , but to stimulate the attention of brethren ,
