The body of the work, however, is fruitful in seminal ideas, though some statements may be rash and some conclusions extravagant.

Each testis communicates by means of an efferent duct with a common collecting duct of its side of the body, which opens on to the exterior by means of a protrusible penis, and to which is sometimes appended a seminal vesicle.
These ducts therefore have not their exact counterparts in the Oligochaeta, unless we are to assume that they collectively are represented by the seminal vesicles of earthworms and the vasa deferentia.
In some cases while the original aperture remains undivided, the seminal groove is closed and so converted into a canal.
But when the male secretion of the ovo-testis is active, the seminal fluid passes from the genital pore along the spermatic groove (fig.
Genital duct diaulic, without open seminal groove; male and female apertures contiguous.
The paired testes of the male consist of a variable number of seminal From Miall and Denny, The Cockroach, Lovell Reeve & Co.
During pairing he thrusts the tip of these organs into the seminal vesicles of the female and the eggs are fertilized as they pass out of the oviduct.
This last was the central and the seminal idea of the work, and it has been the point round which the battle of scholarship has mainly raged.
In 1703 Samuel Morland, in a paper read before the Royal Society, stated that the farina (pollen) is a congeries of seminal plants, one of which must be conveyed into every ovum or seed before it can become prolific. In this remarkable statement he seems to anticipate in part the discoveries afterwards made as to pollen tubes, and more particularly the peculiar views promulgated by Schleiden.
The male organs are usually a testis, a large seminal bladder and a protrusible penis.

They pass out through short vasa deferentia with internal ciliated funnels, sometimes an enlargement on their course - the seminal vesicles - and a minute external pore situated on the side of the tail.
After dividing plants into flowerless and flowering, Ray says, "Floriferas dividemus in Dicotyledones, quarum semina sata binis foliis anomalis, seminal ibus dictis, quae cotyledonorum usum praestant, e terra exeunt, vel in binos saltem lobos dividuntur, quamvis eos supra terrem foliorum specie non efferunt; et Monocotyledones, quae nec folic bina seminalia efferunt nec lobos binos condunt.
It is interesting to observe that here already two things are brought forward as proofs of the omnipotence and care of God: one is the creation of man out of a seminal drop - an idea to which Mahomet often recurs; the other is the then recently introduced art of writing, which the Prophet instinctively seizes on as a means of propagating his doctrines.
Catholicism was considered as an organic growth, developing from certain seminal principles in accordance with certain definite laws.
It was not till 1840 that his Confessions of an Inquiring Spirit, by far his most seminal work, was posthumously published.
It would be the seminal accomplishment of humanity.
