vity full of clotted blood. I no longer doubted that this was the place where 

 this infant was formed, and I conceived that having acquired in this place a 

 growth too great to be able to fall in time; and having continued to grow 

 there, without being able to come forth, it had at length broken its prison 

 by stretching it. 



I was confirmed in my opinion when comparing this testicle (ovarium) with 

 the left, I found it at least four times larger, its size approaching that of a hen's 

 tgg; and the left being not greater than a little chesnut; it was all red without 

 and within, besides the clotted blood that it contained ; whereas the left was 

 pale and full of little grains of the colour and consistency of yellow tallow. 



I examined]the tube on the right side; and I could not find that this infant had 

 ever entered there ; it was in all things like the left tube. 



Lastly, I examined the body of the womb with all the care and exactness 

 that might be. It appeared to me every where without any rent, and in a state 

 purely natural : I only observed, that it was a little larger and softer than it is 

 found in women who die without being with child : it was all as Dr. Harvey has 

 described it, in the first month of pregnancy. I caused a probe to be put into 

 its cavity by the vagina, and then to be cut open, and I found not the least 

 sign of conception. Indeed the vessels of the interior membrane appeared to 

 me full of blood. 



Authors speak of certain foetuses found in the tubes ; and of others that have 

 been found in the cavity of the belly, neither the womb, nor the tubes being 

 any way torn: but I do not think that any person hitherto has been able 

 to show, that the conception is made in the testicle or ovarium, as it seems to 

 me that the fact, which I have now related, manifestly demonstrates.

ExPT. I. j4 Parallel betwixt Lightning and Phosphorus. 

 In order to keep the solid phosphorus from wasting, I usually placed it at the 

 bottom of a glass of water. Having several of these glasses disposed on a table 

 in view, whilst I lay on my bed, I could observe several flashes of light that 

 successively passed through the water, and made such bright and vigorous co- 

 ruscations in the air, as would surprize and afFrighten one not used to the phe- 

 nomenon. This fiery meteor passes somewhat contracted through the incum- 

 bent water, but expands itself as soon as it gets above it. To make these 

 experiments to advantage, the glass ought to be deep and cylindrical, and not 



above 3-4ths filled with water.
