authors whose works I then recommended。  I recommend them still; 

though a swarm of other manuals and popular works have appeared 

since; excellent in their way; and almost beyond counting。  But all 

honour to those; and above all to Mr。 Gosse and Mr。 Johns; who 

first opened people's eyes to the wonders around them all day long。  

Now; we have; in addition to amusing books on special subjects; 

serials on Natural History more or less profound; and suited to 

every kind of student and every grade of knowledge。  I mention the 

names of none。  For first; they happily need no advertisement from 

me; and next; I fear to be unjust to any one of them by 

inadvertently omitting its name。  Let me add; that in the 

advertising columns of those serials; will be found notices of all 

the new manuals; and of all apparatus; and other matters; needed by 

amateur naturalists; and of many who are more than amateurs。  

Microscopy; meanwhile; and the whole study of 〃The Wonders of the 

Little;〃 have made vast strides in the last twenty years; and I was 

equally surprised and pleased; to find; three years ago; in each of 

two towns of a few thousand inhabitants; perhaps a dozen good 

microscopes; all but hidden away from the public; worked by men who 

knew how to handle them; and who knew what they were looking at; 

but who modestly refrained from telling anybody what they were 

doing so well。  And it was this very discovery of unsuspected 

microscopists which made me more desirous than ever to see … as I 

see now in many places … scientific societies; by means of which 

the few; who otherwise would work apart; may communicate their 

knowledge to each other; and to the many。  These 〃Microscopic;〃 

〃Naturalist;〃 〃Geological;〃 or other societies; and the 〃Field 

Clubs〃 for excursions into the country; which are usually connected 

with them; form a most pleasant and hopeful new feature in English 

Society; bringing together; as they do; almost all ranks; all 

shades of opinion; and it has given me deep pleasure to see; in the 

case at least of the Country Clubs with which I am acquainted; the 

clergy of the Church of England taking an active; and often a 

leading; interest in their practical work。  The town clergy are; 

for the most part; too utterly overworked to follow the example of 

their country brethren。  But I have reason to know that they regard 

such societies; and Natural History in general; with no unfriendly 

eyes; and that there is less fear than ever that the clergy of the 

Church of England should have to relinquish their ancient boast … 

that since the formation of the Royal Society in the seventeenth 

century; they have done more for sound physical science than any 

other priesthood or ministry in the world。  Let me advise anyone 

who may do me the honour of reading these pages; to discover 

whether such a Club or Society exists in his neighbourhood; and to 

join it forthwith; certain that … if his experience be at all like 

mine … he will gain most pleasant information and most pleasant 

acquaintances; and pass most pleasant days and evenings; among 

people whom he will be glad to know; and whom he never would have 

known save for the new … and now; I hope; rapidly spreading … 

freemasonry of Natural History。



Meanwhile; I hope … though I dare not say I trust … to see the day 

when the boys of each of our large schools shall join … like those 

of Marlborough and Clifton … the same freemasonry; and have their 

own Naturalists' Clubs; nay more; when our public schools and 

universities shall awake to the real needs of the age; and … even 

to the curtailing of the time usually spent in not learning Latin 

and Greek … teach boys the rudiments at least of botany; zoology; 

geology; and so forth; and when the public opinion; at least of the 

refined and educated; shall consider it as ludicrous … to use no 

stronger word … to be ignorant of the commonest facts and laws of 

this living planet; as to be ignorant of the rudiments of two dead 

languages。  All honour to the said two languages。  Ignorance of 

them is a serious weakness; for it implies ignorance of many things 

else; and indeed; without some knowledge of them; the nomenclature 

of the physical sciences cannot be mastered。  But I have got to 

discover that a boy's time is more usefully spent; and his 

intellect more methodically trained; by getting up Ovid's Fasti 

with an ulterior hope of being able to write a few Latin verses; 

than in getting up Professor Rolleston's 〃Forms of Animal Life;〃 or 

any other of the excellent Scientific Manuals for beginners; which 

are now; as I said; happily so numerous。



May that day soon come; and an old dream of mine; and of my 

scientific friends; be fulfilled at last。



And so I end this little book; hoping; even praying; that it may 

encourage a few more labourers to go forth into a vineyard; which 

those who have toiled in it know to be full of ever…fresh health; 

and wonder and simple joy; and the presence and the glory of Him 

whose name is LOVE。







APPENDIX。







PLATE I。







ZOOPHYTA。  POLYZOA。



THE forms of animal life which are now united in an independent 

class; under the name Polyzoa; so nearly resemble the Hydroid 

Zoophytes in general form and appearance that a casual observer may 

suppose them to be nearly identical。  In all but the more recent 

works; they are treated as distinct indeed; but still included 

under the general term 〃ZOOPHYTES。〃  The animals of both groups are 

minute; polypiform creatures; mostly living in transparent cells; 

springing from the sides of a stem which unites a number of 

individuals in one common life; and grows in a shrub…like form upon 

any submarine body; such as a shell; a rock; a weed; or even 

another polypidom to which it is parasitically attached。  Each 

polype; in both classes; protrudes from and retreats within its 

cell by an independent action; and when protruded puts forth a 

circle of tentacles whose motion round the mouth is the means of 

securing nourishment。  There are; however; peculiarities in the 

structure of the Polyzoa which seem to remove them from 

Zoophytology to a place in the system of nature more nearly 

connected with Molluscan types。  Some of them come so near to the 

compound ascidians that they have been termed; as an order; 

〃Zoophyta ascidioida。〃



The simplest form of polype is that of a fleshy bag open at one 

end; surmounted by a circle of contractile threads or fingers 

called tentacles。  The plate shows; on a very minute scale; at 

figs。 1; 3; and 6; several of these little polypiform bodies 

protruding from their cells。  But the Hydra or Fresh…water Polype 

has no cell; and is quite unconnected with any root thread; or with 

other individuals of the same species。  It is perfectly free; and 

so simple in its structure; that when the sac which forms its body 

is turned inside out it will continue to perform the functions of 

life as before。  The greater part; however; of these Hydraform 

Polypes; although equally simple as individuals; are connected in a 

compound life by means of their variously formed POLYPIDOM; as the 

branched system of cells is termed。  The Hydroid Zoophytes are 

represented in the first plate by the following examples。





HYDROIDA。





SERTULARIA ROSEA。  PL。 I。 FIG。 6。



A species which has the cells in pairs on opposite sides of the 

central tube; with the openings turned outwards。  In the more 

enlarged figure is seen a septum across the inner part of each cell 

which forms the base upon which the polype rests。  Fig。 6 B 

indicates the natural size of the piece of branch represented; but 

it must be remembered that this is only a small portion of the 

bushy shrub。





CAMPANULARIA SYRINGA。  PL。 I。 FIG。 8。





This Zoophyte twines itself parasitically upon a species of 

Sertularia。  The cells in this species are thrown out at irregular 

intervals upon flexible stems which are wrinkled in rings。  They 

consist of lengthened; cylindrical; transparent vases。





CAMPANULARIA VOLUBILIS。  PL。 I。 FIG。 9。





A still more beautiful species; with lengthened foot…stalks ringed 

at each end。  The polype is remarkable for the protrusion and 

contractile power of its lips。  It has about twenty knobbed 

tentacula。





POLYZOA。





Among Polyzoa the animal's body is coated with a membraneous 

covering; like that of the Tunicated Mollusca; but which is a 

continuation of the edge of the cell; which doubles back upon the 

body in such a manner that when the animal protrudes from its cell 

it pushes out the flexible membrane just as one would turn inside 

out the finger of a glove。  This oneness of cell and polype is a 

distinctive character of the group。  Another is the higher 

organization of the internal parts。  The mouth; surrounded by 

tentacles; leads by gullet an
