An Essay on the Nature of Heat, Light, and Electricity. By. 
CHaries CARPENTER Bompass, Barrister al Law. 8vo,. 
276 pp. 
This is a work of uncommon merit, and will, we are confident,, 
be well received by those whose minds have been properly disci- 
plined by the strict laws of the inductive philosophy. The author. 
in his preface apologizes for offering an essay on a branch of 
natural philosophy, unsupported by experiments of his own s 
but we think the chances are at least equal, that he would not 
have produced a more useful work, had he had experiments of 
his own to detail, and the results to explain. He has done bet- 
ter in founding his observations on the labours which others, “ in 
return for the honours so justly paid them, have surrendered for 
public use ;”’—for, had he offered new experiments and new re- 
sults;the attention of the reader (if net his own) would have been 
diverted from the main object of the essay; or at least divided, 
and the author would have produced less effect. 
The work is divided into chapters, and these into sections. 
Chap. 1, ON THE. Narure or Heat. § 1. On the Materiality, 
of the Cause of Heat. § 2. On Attraction for Caloric, Latent 
Heat,and Evaporation. § 3. On the Communication of Caloric. 
§ 4. On the Reflection of Caloric. § 5. On the supposed Re- 
pulsion between the Particles of Caloric—and the Elasticity of 
Gases. § 6. On the Nature of the Attraetion for Caloric.— 
Chap. 11. On THE Nature oF Ligur. § 1. On the Mutual 
Relations of Light and Caloric. § 2. On the Reflection of 
Light—and Visibility of Bodies. § 38. Gn the Component Parts 
of Light—and the Causes of Colour. Chap. II]. On Execrri- 
city. § 1. On the Formation of the different Kinds of Electri- 
city. § 2. On the Nature of Electrical Attraction. § 3. On 
the Franklinian Hypothesis: § 4. On the Cowbination of the 
Two Kinds of Electricity, and the Identity of the Compound 
Ethereal Fluid with Calorie and Light. 
It would not be justice to the author to offer an analysis of a 
work which is wholly argumentative: we shall therefore confine 
ourselves chiefly to a statement of some of his conclusions :
