Seeing, by the report of the last meeting of the Horticultural Society, that my brother has succeeded in fruiting and ripening wood and fruit of the Black Hamburgh Grape from eyes struck in February last, I beg to state that I have got good bunches and well-swelled berries of Muscat of Alexandria, on vines struck from eyes in March last. The vines were not stopped at 15 inches high, as his were, but at eight feet, consequently the fruit is produced on the laterals. I would particularly recommend those about planting vineries, if they have the convenience, to strike their own plants in February or March, and plant them out in May or June. Some which I have treated in this way here in our new vineries, surpass two-year old plants planted in April. R. Elphinstone. lb.

* There is. however, one tact which Would almost lend one to ouppose that the ova are impregnated 12 months before emission. It is this. - the male par (salmon fry,) are at this season full of milt, and almost ready for ems-sious; whilst m the females, the ova are so small, that theyre-quiru a microscope to see them individually, and the whole ovary is merely like a thread: either the millt of the male is not required to impregnate the roe of the female, or the roe is impregnated long before emission. for the roe of the female par evidently requires many months to bring, it to molarity; but my opinion is, if a female salmon were to ascend a river without being accompanied by, or meeiing with a mile, that the roe would be impregnated by the malt par. which always swarm about the salmon spawn-ine beds,and the experiment* of the Duke of Hurclcuch'a game-keeper (Suavv.) lend to prove that this is the fact - the same excess of males many be desirable that exists in a bee-hive, where there are, at least, a thousand males for one female.
