 for food — but I allow him only ricQ. and s32;<j — declines 

 milk. He appears now to be free from all complaint. 

 Aher this time nothing remarkable occurred. He had a 

 strong appetite, and was allowed vci^^elable curry. For se- 

 veral evenings some heat of skin and acceleration of pulse 

 were perceptible ; but these soon went oO', from cold bathino- 

 and a constant attention to keep his bowels in an open 

 state. 



Monday, May 18th, (I4th day.) — Has been for some 

 days past on the usual hospital diet — and feeling himself 

 well in every respect, now expresses a wish to be discharged 

 and return to his usual business ; but as the weather is ex- 

 ceedingly hot (thermometer in the shade from 95° to 100°), 

 I have prevailed upon him to continue in the ho=j)ital till the 

 setting in of the rains. — I shall then, if possible, persuade 

 him to remain in my own employment for the next twelve 

 months; lest, if he were discharged, and should happen to 

 die of whatever disease, it might be alleged that he was aiter 

 all carried oft' by a relapse of the hydrophobia.

J. HE author has very laudably endeavoured to render the 

 difficult subject of crystallography familiar to persons un- 

 acquainted with geometry. The task was somewhat ar- 

 <luous; Init those who cannot coinprehend his figures and 

 descriptions, may have recourse to his models, which super- 

 sede the necessity of mathematical knowledge, ili.s uio- 

 dels amount to fifty, his figures to 103, \\hkh embrace 

 nearly all the ditltrent fotnis of crystalline bodies. As 

 crystallography is rather a new science, the necessity of ele- 

 mentary or introductory treatises on it must be obvious. 

 Hitherto nothing of the kind has appeared either in France
