the ventricle in the mouse and white rat with results of a brilliancy 

 characteristic of his recent work. 



A fine interlamellar net-work is spread through the whole thick- 

 ness of the heart muscle and extends from the auriculo-ventricular 

 groove to the extreme apex of the ventricle with fibres of medium and 

 very small size. The main fibres extend generallv in the direction of 

 the axis of the muscular bundles, spreading out and giving off branches 

 dichotomously as they proceed. These branches either join other 

 fibrillee or send out terminal filaments with knob-like extremities either 

 between the muscle fibres or on the bundle. In addition to the above 

 are fibres of a larger calibre without varicosities or connections with 

 the net-work. They follow undulating courses between the muscular 

 spindles and end in large and intricate figures. In the path of these 

 fibres, not far from the termination, is a ganglion cell of ovoid form. 

 The author inclines to regard these as sensory termini. Between the 

 sarcous elements are bipolar nerve cells. Their rami ramify between 

 the muscular elements, in some cases with curious arborescent termini. 

 Axis cylinders were not seen. These are regarded as sympathetic ele- 

 ments. 



A large plexus of coarse ganglionic thickenings occurs among the 

 nerve fibres between the muscular bundles of the ventricle, compara- 

 ble to the plexus of the Auerbach in the intestine. 



The Primer of Pliilosopliy.' 



Among the results of scientific progress during the last decade or 

 two has been the dawning of the idea that everything is not explained 

 by a few natural laws, an indefinite quantum of matter and time ad 

 libitum. Thus we enter upon a period of reconciliation of philosophy 

 and physical science, of religion and evolution. Whatever we may 

 think of the early stages of the process, it is satisfactory to realize that 

 monism is the recognition of the supremacy of the metaphysical and a 

 proof that the human mind will not long remain content with a God-less 

 or disarticulated universe. In the book before us we have an attempt to 

 prepare the way for a reconciliation. Without sharing altogether in the 

 author's optimism respecting the immediate future of philosophy, or 

 more particularly this philosophy, we do find much to commend, espec- 

 ially in the vigorous disillusioning respecting sundry bits of hoary 

 nonsense which are bruskly kicked out of the way. Translating the
