ratus may be placed which israther for gen- 
eral and common than for personal use. 
A candid examination of these six plans 
will, I hope, convince the reader that the 
proposed unit-room provides thoroughly 
convenient, but not excessive, accommoda- 
tions for twenty-four students, and that the 
students may be distributed in many differ- 
ing ways, according to special needs. It 
has not seemed worth while to pursue these 
plans further, with a view of showing how 
a smaller number ofadvanced workers could 
be disposed. The solution of such a problem 
is so simple as not to require illustration. 
If such a room is to be used for a collection, 
two cases could be arranged along the side

there are two symmetrically placed wings, 
which, building space permitting, can be in- 
definitely extended, whenever enlargement 
shall become necessary. The second study, 
by myself, is merely a modification of the 
first: the size of the unit room is 23x30 
feet, one room being drawn subdivided for 
assistant’s use; the main building has been 
lengthened in order to provide small rooms 
near the lecture hall, and to increase the 
distance between the wings so as to secure 
better light; in order not to increase the 
floor space the wings are drawn shorter. 
Neither of these studies is to be regarded 
as more than a preliminary sketch, which 
needs competent revision and modification

wall, and if there are three windows, two 
sets of double cases could be placed against 
the space between the windows and run into 
the room as do the double rows of tables in 
the zoology plan. 
In conclusion, attention is asked to the 
two studies fora floor plan. The first study 
is by Professor W. T. Porter, of the Harvard 
Medical School, to whose generous courtesy 
I am indebted for the opportunity to pub- 
lish the plan for the first time. In this 
study the unit size adopted is 20x 380 feet, 
but I have Dr. Porter’s permission to state 
that he considers 23x30 feet preferable. 
In this study there is a central large lecture 
room connected with the main building, and

become practically available. They suffice, 
however, for the purposes of this article and 
to illustrate the construction of a laboratory 
upon the unit system.
