APPENDIX 



SUGGESTIONS FOR LABORATORY WORK 



To a greater and greater extent colleges and normal schools are 

 supplementing text-book instruction in Physiology with practical 

 work in the laboratory. For such work laboratory instructions 

 must be provided. There are upon the market numerous excellent 

 laboratory manuals of Physiology, but most of them have been 

 prepared for use in Medical Schools, and with the needs of Medical 

 Students primarily in mind. The aim of this appendix is to furnish 

 a basis for the preparation of a manual suited to the needs of the 

 students who are pursuing the subject non-prof essionally. The 

 complete equipment of a Physiological laboratory is rather ex- 

 tensive, and in many cases not available in entirety. The time 

 which can be devoted to laboratory work in Physiology varies 

 greatly in different institutions. For these two reasons it has 

 seemed best not to offer in this connection a manual of se- 

 lected experiments, but rather to suggest simple exercises that 

 can be adapted by the teacher to his particular require- 

 ments. 



The special character of much of the work of the physiological 

 iboratory demands a certain amount of special preparation on the 



irt of the teacher. In describing the following experiments this 

 reparation is assumed. The majority of teachers of Biology have 

 it. For those who have not, and wish to introduce in their classes 

 iboratory work in Physiology, resort may be had to one of the 

 imer courses in Physiology now offered by the larger Universi- 

 ties in various parts of the country. 



Fortunately for the successful development of laboratory Physi- 

 ology in America the special apparatus required can be obtained of 

 American manufacture and at a moderate price. Information as 

 to where such apparatus may be sought can be had upon applica- 

 tion to the department of Physiology in any of the larger Uni- 

 versities.
