Except in the depauperation of the floral envelopes, a point evidently of little comparative importance, since we see that the nobler objects of the vegetable world are most fre- quently those whose floral envelopes are the least developed, it would be difficult to point out one single particular in which Conifers are inferior to other arboreous Exogens. The very slow development of the fruit should, on the contrary, seem to indicate superior dignity. Tt may be true, indeed, that spiral vessels are comparatively rare in the trunk, but then the presence of these in abundance is no sure evidence of superiority, and even admitting their infrequency to be a mark of inferiority, the wood cells are more complicated](https://iiif.wellcomecollection.org/image/b2191574x_0048.jp2/full/800%2C/0/default.jpg)
