of the inner nasal bones, the e.yes appear not to have been disturbed, 

 the tongue was entire, and the teeth white and perfect. 



Dr. Granville next proceeds to draw some conclusions as to the 

 age at which this mummied female died, and respecting the disease 

 which destroyed her. The bones of the ileum exhibit that peculiar 

 thinness of their osseous plates which show the individual to have 

 exceeded her fortieth year, and to have borne children ; and as there 

 are no characters of age or decrepitude about the skeleton, the au- 

 thor considers her to have been about fifty. The ovarium and broad 

 ligament of the right side were enveloped in a mass of diseased struc- 

 ture, while the Fallopian tube of the same side was sound ; but the 

 uterus itself was larger than natural, and the remains of a sac were 

 found connected with the left ovarium ; all which, connected with 

 the appearance of the abdominal integuments, leave no doubt of 

 ovarian dropsy having been the disease under which the individual 

 suffered. 



The author concludes this communication with some observations 

 respecting the method of embalming generally, and the nature of the 

 substances employed in the process, from the details of which he 

 draws the following conclusions : 



The abdominal viscera were more or less perfectly extracted, 

 either through an incision on one side of the abdomen, or, as in the 

 present mummy, through the anus. The thoracic cavity was not 

 disturbed. The contents of the cranium were removed sometimes 

 through the nostrils, and in others through one of the orbits. 

 The body was then probably covered with quick-lime, to facilitate 

 the removal of the cuticle, the scalp and nails being, however, left 

 untouched ; after which, it was immersed in a melted mixture of wax, 

 resin, and bitumen, until thoroughly penetrated ; and ultimately sub- 

 jected to a tanning liquor, probably made with the saline water of 

 the neighbouring natron lakes. The bandages were applied with the 

 occasional interposition of melted resin, or wax and resin, the lumps 

 of resin, myrrh, &c., having been previously placed in the abdomen. 



On the temporary Magnetic Effect induced in Iron Bodies by Rotation. 

 In a Letter to J. F. W. Herschel, Esq. Sec. R.S. by Peter Barlow, 

 F.R.S. Communicated April 14^, 1825. Read May 5, 1825.

The author's attention having been recalled to the consideration 

 of the effects of rotation in altering the magnetic influence of iron, 

 in the course of speculations on the cause of the rotation of the earth's 

 magnetic poles ; and knowing, at the same time, that Mr. Christie 

 had found a permanent change in the magnetic state of an iron plate,, 

 by mere change of position on its axis, it seemed to him highly pro- 

 bable that this change, due only to a simple inversion, would be in- 

 creased by rapid rotation. On trial, however, it was found that the 

 effect produced was merely temporary. The experiments at first 

 were made with a 13 -inch mortar shell, fixed to the mandrel of a.
