PART I.— MORPHOLOGY AND CULTURE OP MICROORGANISMS 



General (Editor). Outline of Plant Groups (Thorn) 

 Outline op Protozoal Groups (Todd) (Tjrzzer) 



CHAPTER I. — Elements of Microbial Cytology (Guilliermond) is 



Cells and energids. — Structure of the cell, — Nuclear structure (general structure of 

 the nucleus, oentriole, value of the nucleus, forms of nuclei, theory of binuclearity), 

 cytoplasm (appearance of protoplasm, chondriosoines, vacuoles, reserve products), 

 membrane, locomotion. — Reproduction, — Various processes, nuclear division (mito- 

 sis, amitosis), sexual changes. 



CHAPTER II.— Molds (Thorn) 36 



Fungi in general,^Bacteria, Phycomycetes, Ascomycetes, Basidiomycetes, Imper- 

 fect fungi. — Cytology of molds, — 'General structure of molds, cytoplasm, nuclei, 

 metachromatic corpuscles and reserve products, cell wall. — Molds, — Cosmopolitan 

 saprophytes, molds of fermentation, parasites and facultative parasites. — Consitfera- 

 tion of groups, — Muqpr, Penicillium, Aspergillus, Cladosp'orium, Alternaria and 

 Fusarium, Oidium, Motiilia, Dematium. 



PHAPTER III.— Yeasts (Bioletti) S9 



Morphology of certain types, — Definition and bases of classification. — Cytology, — 

 General structure of yeasts, cytological phenomena during multiplication, variation 

 in the cellular structure during development, cytological phenomena of the sporula- 

 tion and gbm^nation of ascospores. — The principal yeasts of importance to fermenta- 

 tion industries, — True yeasts, pseudo-yeasts. — Culture of yeasts. 



CHAPTER IV.— Bacteria (Frost) 77 



Form, — Fundamental form types, gradations, involution forms. — Size-: — Motility, — 

 Brownian movement, vital movement, organs of locomotion, character of move- 

 ment, rate. — Reproduction, — Vegetative multiplication, spore formation. — Cell 

 grouping.^Cytology of bacteria, — General consideration of cytoplasm and nucleus, 

 minute consideration of cytoplasm and nucleus, life cycle of bacteria, reserve 

 products, general structure of cell wall, minute structure of cell wall, general con- , 

 sideration of flagella, minute consideration of flagella. — Higher bacteria.^Classifi- 

 cation. — Relationship of bacteria. — Cultivation of bacteria. 



CHAPTER V. — Invisible Microorganisms (Dorset) .116 



A brief general discussion of the available knowledge of invisible microSrganisms. 



CHAPTER VI.— Protozoa (Todd, revised by Tyzzer.) 120 



Introduction.— Structure of protozoa. — Activities of protozoa, — Locomotion and re- 

 production, developmental cycle, encystment. — Parasitism. — Discussion of classifi- 

 cation. — Technic.
