156 The Fungoid Origin of Disease, 



his last addition " enables him to rule lines at any required angle 

 with the Hne of movement given to the diamond point ; so that, 

 assuming the latter to move — as in my machine — 1 in 1000 " for each 

 rotation of the leading screw, I can rule lines closer to each other in 

 the relation of the cosine of the angle from a perpendicular to the 

 path of the diamond." 



The glass or steel disk is rotated through any azimuth angle by 

 means of a " worm-wheel " and endless screw. 



In a note received after the preceding remarks were written, 

 Mr. Stanistreet says, " I think I ought to mention a fact connected 

 with the last specimen that I sent you. After completing the ten 

 rays of the star I went on ruling another ray, supposing that I had 

 still one to do, and I had ruled three supernumerary lines before my 

 eye caught the index which told me that I had completed the cir- 

 cumference. I expect that the work would be marred by this 

 excess, but on removing it from the machine I was unable to per- 

 ceive any trace of irregularity, and it was only under the microscope 

 that I found the three supernumerary hues occupying almost 

 EXACTLY the site of the three first Hues." The error is of no prac- 

 tical value ; it would escape all ordinary notice, and serves to show 

 the accuracy of the apparatus. 



Mr. Stanistreet speaks most modestly of his machine, and of his 

 work, as if it were easy. We may congratulate him on such a 

 happy imperviousness to difficulty, and wish his further labours all 

 success. 



yil. — The Fungoid Origin of Disease, and Spontaneous Generation. 

 By Jabez Hogg, Hon. Sec. E.M.S. 



In the report of the medical officer of the Privy Council just issued, 

 the origin and pathology of contagion is ably discussed, and the 

 crude hypothesis of HalUer bearing upon this point, who, it will be 

 remembered, sought to prove that the microzymes and sporules of 

 fungi which he found in the fluids of persons afiected with cholera 

 caused the disease and explained its contagious nature, is finally 

 disposed of. This vexed question, one of no small importance to the 

 public, and of great interest for the medical profession, receives at 

 the hands of Dr. Sanderson, the writer of this part of the report, 

 all the care and attention it really deserves. His experiments and 

 investigations fully bear out all I have stated on this subject, and 

 conclusively show that neither bacteria nor microzymes are con- 

 cerned in the production of any specific form of disease in the 

 hving animal body, and therefore when found must be looked upon 

 as an indication of a putrefactive process occurring after death. A
