&c., &c., best admitted of their distribution and position in the 
cabinets. 
The Histological Series of the College of Surgeons is contained 
in two large mahogany cabinets, with double folding-doors. Each 
cabinet is divided into four vertical rows of drawers, with sixty-three 
drawers in every row. The drawers themselves are subdivided 
into four compartments, each of which holds eleven slides, 3 inches 
by 1 inch in size. The lowest drawer in all the rows is extra deep, 
namely, includes two ordinary drawers ; in these more than usually 
deep-celled preparations are kept. Cabinet No. 1 is devoted to the 
Physiological and Pathological Series ; cabinet No. 2 includes the 
Natural History Series. The main grouping follows the order of 
the succeeding tables ; but these, it is to be noted, do not embrace 
every minor subdivision, as this would have involved too great an 
extension of what is already long enough. The manner of num- 
bering, labelling, &c., shall be discussed as I proceed farther on.
