Preface—
Begins with the author’s expression of his gratitude to his professional colleagues of India for their commendations of the monograph on intermittent fever, which was published in 1879. 
The treatment of intermittent fever prevalent during that time was mainly by the administration of massive doses of quinine. This type of suppressive treatment practiced by the dominant school of medicine is not only positively injurious but also often fatal. Massive doses of Peruvian bark or any of its alkaloids can only suppress the symptoms and there by increase the suffering of the patient. 
Hahnemann’s lesson in the “ chronic diseases” on the treatment of acute syphilis must be applied to fevers of all types and acute diseases of every name and every kind irrespective of habitat. 
“Therapeutics of fever ” deals with therapeutics of typhoid, typhus and fevers of every grade and name, from acute sporadic and epidemic intermittent to the malignant type of the malarial fevers of the tropics. 
At the end of the end of the preface author express his obligations to Drs. Geo. H. Clark, C.B. Gilbert, Wm.Guernsey, St. Clair Smith, E.V.Rose and P.C.Mujumdar for valuable suggestions; and to Drs. C.E.Fisher and C.B. Hall for suggestions and proof reading.

Merits: 
Less importance is given for pathological rubrics. (Or limited number of pathological rubrics are given Eg: - Typhoid, yellow fever, Zymotic etc) which shows that the author has given more importance to symptomatology.
It contains many additional rubrics when compared to other repertories.
E.g.: - Chill location of
Ø Abdomen
Ø Arms
Ø Arm left
Ø Back, in, or on the etc
Cause
Ø  Mechanical injuries from
Ø  Organic lesion  
Whole febrile condition is divided in to four stages i.e. chill, heat, sweat and apyrexia. Each of these stages further subdivided into type, time, location of, cause etc. There by the selection of the rubrics become more accurate and easier.
General accompaniment of the fever are given separately- begins from symptoms of the mind and ends with constitutional and general. But in other repertories these symptoms has to be looked in regional chapters.
The book has got both materia medica part and repertory part so one can use it for easy reference.

Demerits:  
Misplaced rubrics are many.
Repetition of same rubrics in different chapter with different medicines.
No definite pattern or order for the arrangement different chapters.
Limited number of medicines when compared to Murphy or other modern repertory.
Even though grading is given as bold, Italics and ordinary letters, there is no information about it s mark.
Rubrics are given in alphabetical order but in some places this order is not
Followed. Eg: - under the chapter “Chill- type” the rubric- “Fever, without chill, returning at” is given in wrong alphabetical order.  
Under the section chill, there were two chapters with the same heading with entirely different rubrics. i.e. “symptoms during the chill” and “chill, symptoms during”
Under the section general accompaniment of the fever; symptoms of diarrhea, constipation, urine, voice, breathing, cough, heart, back, extremities, sleep, skin, sweat, tissues and constitutional and general are given under the heading “gastric” instead of given as separate chapters.
