Ill 
sketch of the labours of Dr Fleming has already been laid before 
the Society. A brief notice of Professor Gregory has been drawn 
up by Dr Alison, and he has come here to-night to present it to the 
Society in person. Time and opportunity have been wanting to me 
to collect extensive information respecting Mr Tod and Mr Jardine ; 
whilst in the cases of Mr Jamieson Torrie and Mr Morries Stirling, 
I have had the advantage of the kind assistance of Dr Balfour, Dr 
Christison, and Mr Andrew Coventry. 
Suffice it to say, that Mr Tod was for no less than twenty-nine 
years Secretary to the Royal Scottish Society of Arts, the duties of 
which office he discharged with such efficient and ready zeal as to 
have rendered himself ultimately the centre and moving power of 
that Society, by every member of which he was highly and deservedly 
esteemed. On our own meetings he was a regular attendant ; but 
he reserved his active energies for the Society to which his tastes 
and his official position more directly attached him. As a disinter- 
ested patron of youthful inventors, as a friend to every unfriended 
projector, his loss will be severely felt. 
Of Mr Jardine all I can collect is, that he possessed keen intel- 
ligence and great mathematical powers. In his early career he is 
said to have given promise of the highest eminence, attracting the 
attention of Professor Playfair, to whom he was under deep obliga- 
tions. I possess a copy of a book presented to him by the author — 
the Supplement to Legendre’s u Theorie cles N ombres The testi- 
mony, even to this extent, of so distinguished a man as Legendre, 
is no small matter. Mr Jardine appears to have been too easily 
satisfied with the position which his professional skill as a civil 
engineer secured him, to admit of his using the exertion requisite for 
figuring in a broader sphere. His attainments, however, were by 
no means limited to a knowledge of his profession. 
Fifty years ago, when geology was not a common study, Mr 
Jardine laboured in that field ; but the fruits of his labours were, so 
far as I know, communicated only to his friends. It was a merit 
even to study amongst the rocks in those days ; when the country - 
people were not accustomed, as they are now, to meet with gentle- 
men converted for the time into stonebreakers. Professor Sedg- 
wick tells a story of his arriving late, hammer in hand, and 
groaning under a load of specimens, at a little inn in some remote 
district, and of the worthy Boniface bringing out in turn each of his
