shelves; Acrogens on the right, having the Lycopodiacese and Marsileacese on 

 the highest shelves. The Monocotyledonous plants would occupy the next 

 elevation, or second range of cases; the Gymnosperm Dicotyledons the third 

 range, and the Anjiospcrm Dicotyledons the fourth or last ; if too numerous for 

 this range, then the last might encroach on the right of the Gymnosperms or 

 Coniferse, in range of cases just below, viz., the third. 



1). Middle or second story. The west half is the music-room, with a portion 

 of the wall painted in white staves on a black ground ; also with a monochord, 

 for estimating vibrations and explaining the principles of the scale ; a metronome, 

 so that time may be definite, not arbitrary ; tuning-forks, pendulums of two dif- 

 ferent lengths, one to vibrate common time, the other quick time, for drilling 

 young drummers, in connexion with the military organization. Here, too, if an 

 instrumental band could be formed, they would practice and give occasional 

 concerts. In the east half is the drawing-room; it should have numerous plaster 

 figures, besides models of ears, eyes, noses, arms, &c., also blocks of every size 

 and shape, comprising the geometrical solids. This room should be so arranged 

 as to admit the light from the upper part of the windows ; and as perspective 

 should be taught, there ought to be here the usual illustrative apparatus, con- 

 sisting of threads passing through apertures in a pane of glass, to exhibit the 

 principles upon which the art is based, besides having them theoretically ex- 

 plained in their geometrical studies. 



c. Upper or tJiird story. In the west half we might have languages, and 

 suspend all around the walls instructive diagrams for general and special history, 

 also outline and Bother maps for ancient and modern geography, tabular views, 

 exhibiting analogous parts of language or exceptions, typical form of declen- 

 sions, conjugations, c.; rules for gender, in French and German, &c., should 

 also be numerously and conspicuously displayed. In the east half we place the 

 department of mathematics, and connect with it all branches of natural phi- 

 losophy, except such as might more appropriately be taught in the laboratory. 

 The mathematical course should embrace algebra, geometry, plain and spherical 

 trigonometry, mensuration, surveying, and navigation; descriptive geometry, 

 shades and shadows, mechanics, optics, acoustics, and astronomy ; also meteorol- 

 ogy. By being in the third story the professors and students are nearer to the 

 observatory, and to the meteorological instruments, for daily note and record of 

 changes. 



(J. A separate building southeast of the main building. This structure might 

 probably be 90 by 65 feet, of two stories. 



a. First story The laboratory for lectures, &c. This room should occupy 

 50 of the 80 feet in length, and be arranged with the necessary furnaces, raised 

 benches for lectures, tables along the sides for students to work at in analyses, 

 &c. The remaining 30 by 65 feet are to be used for blowpipe analyses of 

 minerals, for experiments in electricity and magnetism, in all their modified 

 forms; consequently there would be cases round the room for a good suite of 

 minerals, (the main mineralogical collection being in the geological room,) both 

 arranged from carbon to gold, according to Professor Dana's text-book ; besides 

 a shelf or two to exhibit them, arranged according to their crystals, others to 

 illustrate relative hardness, color, transparency, &c. One or other of these 

 cabinets should also have models of primary and secondary crystalline forms, a 

 goniometer, and other adjuncts to mineralogy. Other cases could have the 

 apparatus connected with electricity and magnetism in all their modifications. 

 This apparatus could be readily taken into the adjoining lecture-room when 

 wanted. The magic-lantern would probably be more appropriately placed here 

 than elsewhere, so as to use it in connexion with the oxy-hydrogen blowpipe. 

 If the professor of drawing could readily paint slides for it, the magic-lantern 

 could be made an endless source of instruction in all departments. 



In one corner should be a balance-room, at least 6 by 10 feet, for all weighing
