Meteorological Observations. 415 
SPERMATOZOA OBSERVED A SECOND TIME WITHIN THE OVUM. 
By Martin Barry, M.D., F.R.SS. L. and E. ' 
Several months since, I communicated to the Royal Society the 
fact that I had observed, and shown to Professor Owen and others, 
spermatozoa within the mammiferous ovum. ‘The ova were those 
of the rabbit, taken twenty-four hours post coitum from the Fallopian 
tube*. 
I have this day confirmed the observation ; several ova from the 
Fallopian tube of another of these animals, in a somewhat earlier 
stage, having presented spermatozoa in their interior: i.e. (as in the 
first observation) within the thick transparent membrane (‘‘ zona pel- 
lucida’) brought with the ovum from the ovary.

Dr. Forster will publish at Bruges in a few weeks, a treatise on 
Comets, entitled “ Essai sur l’Influence des Cométes sur les Phéno- 
ménes de I’Atmosphére terrestre,” &c. ‘To which is appended, “ Essai 
sur les Etoiles filantes, avec une catalogue historique.” 
In March were published at Bruges, “ Discours préliminaire a 
lV Etude de l’Histoire Naturelle,” par T. Forster, F.L.S., F.BR.A.S., &c. 
The object of this Treatise is to direct the student of Natural His- 
tory in the true phrenological method of pursuing the same, and to 
point out the similarity of principleconspicuous through the organized 
animal kingdom. —
