of the day, including Mr. John Whitley and the late Professor 
Davies. His published Papers contain problems of almost 
every grade of difficulty, and may be seen in the Lady's and 
Gentleman’ s Diary, the York Courant, and the Educational 
Times. 
Since his death most of his manuscripts have been com- 
mitted to the care of Mr. Wilkinson, who has selected a series 
of the most curious and interesting to illustrate this Memoir 
of his late valued friend. Several of the problems relate to 
the more difficult portions of the ancient geometry, amongst 
which may be instanced those of inclinations, tangencies, 
sections of ratio and of space, loci, and porisms. One or two 
examples are also given of maxima and minima, bisectant 
axes, besides a series of interesting theorems of considerable 
interest. 
The Memoir closes with a short account of Mr. Buckley’s 
ultimate attainments, his success in life, and the causes 
which led to his premature death “on the 15th July, 1856, 
in the 47th year of his age.”

Mr. Lynde exhibited the circulation in the valisneria, and 
some conversation ensued as to the probable cause of the 
phenomenon. Mr. Lynde considered that the action of light 
influenced the movement of the globules more than that of 
heat, as is generally supposed ; for he found the circulation 
active, in daylight, during cold weather. Mr. Lynde remarked 
that the motion commenced about ten or fifteen minutes after 
the exposure of the specimen to a strong light, while the 
exposure to heat alone would hardly affect it. The point 
could not, however, be determined, owing to the difficulty of
