cause the obliteration not alone of the extensive and interesting 

 minor details of the disturbance, but of many of the greater as well, 

 particularly in the river-beds where the changes of level have oc- 

 curred. The town of San Miguel, three miles north of Babispe, and 

 Bacerac, nine miles south, were uninjured. This is, in view of 

 the principal line of disturbance, particularly interesting. 



I enclose a hasty tracing of the section, which may aid in showing 

 the location of the fault. This does not show the length, for it is 

 too tortuous. Scale of map is about 40 miles to the inch. The 

 mountains as marked are the famed Sierra Madres.

Chemical Laboratory of the University of Nebraska. 



So many requests for the plans and a description of the new 

 chemical laboratory of the University of Nebraska have been re- 



The entrances are in the south and north ends of the building ; 

 that in the south being the main one, while the north door is for 

 the convenience of students coming to the laboratories from the 

 other university buildings. Through this, access is had to every 

 work-room in the laboratory, and to the main lecture-room on the 

 second floor. This arrangement brings classes into the lecture- 

 room from the rear, — an arrangement that will be appreciated by 

 every lecturer on experimental science. 



Entering at the south door, we find ourselves in the vestibule of 

 the first floor. At our right and left, stairways lead to the base- 

 ment floor, as shown in Fig. 3. Descending to the basement corri- 

 dor (Fig. 2), at the front is a large vestibule opening by double 

 side-doors into an area where heavy material is received. Under 

 the stairway to our right is a small room containing the gas-meter. 

 Under the left-hand stairway, and extending across the space oc- 

 cupied by the vestibule, is a ladies' toilet-room. Immediately in 



ceived since its erection, as to warrant the belief that a brief 

 description of its general features would be of interest to the 

 readers of Science, and especially to those who are contemplating 

 the erection of similar buildings, or who are interested in the edu- 

 cational growth of the West. 



The building is situated on the south-east corner of the univer- 

 sity campus, fronting south on R Street. A wide street bounds the 

 east side, while on the north and west is the open campus : thus 

 the building commands an abundance of light from all direc- 

 tions. 



Fig. I shows the south front and east side. The building con- 

 sists of a high basement of native limestone, and a two-story super- 

 structure of the finest St. Louis pressed brick, laid in black mortar 

 and relieved by belt courses of rough limestone. The style of archi- 

 tecture is Romanesque, the broad and heavy stone arches and 

 pointed towers giving to the whole an appearance of massiveness 

 and solidity in keeping with its construction. 



front of the stairway is the ele\'ator shaft. The room at the right 

 serves as a store-room for the basement laboratories, and as a 

 balance-room for the assay and metallurgical laboratory. The 

 corresponding room on the opposite side of the corridor contains 

 a small upright boiler for furnishing distilled water, and large 

 storage-tanks for hydrogen and oxygen gases. It serves also as a 

 storage-room for acids and as a work-shop. The remaining por- 

 tion of this floor is taken up by the general laboratory, where 

 students beginning the study of chemistr)' do their work. This 

 can be used as one large laboratory, accommodating seventy-five 

 students at one time, or, by closing the communicating doors, be 

 divided into two, A and B, A being used as an assay and metallurgi- 

 cal laboratory. 



These rooms have high ceilings, and are well supplied with light. 

 They are ventilated by means of the two large flues C and D, each 

 of which is eight feet broad, and a series of smaller flues built into 

 the side-walls, one between each pair of windows. The large
