48 NOTES AND MEMORANDA. 
That is to say, the point in this paper, as in Balfour’s, is that 
relating to the caudal lobes, which are caused by a thickening of 
mesoblast on each side of the hind end of the embryo at the edge 
of the embryonic rim.—A paper which is partly microscopical is 
on “the Anastomoses of the Hypoglossus Nerve,” by Herr M. Holl. 
—The Lymphatics of the Testicle, by Dr. K. Gerster, of the Patho- 
logical Institute of Bern. This is a good paper. It is illustrated 
by two plates, one plain, and the other coloured. The plain plate 
strikes us as a little too perfect. The staining material used was 
carmine and a combination of carmine and aniline blue, which 
certainly, to judge from the drawing, has acted very well. 
NOTES AND MEMORANDA. 
Death of David Forbes, F.R.S.— One of our great naturalists 
has been taken away from us. David Forbes has died within the 
past month, at the early age of forty-eight years. Most of the labour 
of his life had been spent on his favourite topics, those of mineralogy 
and physical geology. And on these two subjects he has left pro- 
bably far more material behind him than has been already published. 
But in the branch of microscopic geology he has done much good 
work, and of this not the least was the set of papers, splendidly illus- 
trated, which he published in the ‘ Popular Science Review,’ on the sub- 
ject, then a new one, of the ‘“‘ Microscope in Geology.” These papers 
were subsequently reprinted in two German periodicals, so highly 
were they thought of at the time; and they may be said to have led 
English geologists to the pursuit of micro-geology. Of his labours 
in geological science this, of course, is not the place to speak. But 
in conclusion a word may be offered on his personal characteristics. 
David Forbes was, like his famous brother Edward, a man who loved 
truth above all things. He was a keen critic of the scientific doings 
of his fellows, but withal a generous one, and his onslaughts when 
made were usually on his elder and rarely on his younger brethren. 
He was invariably kind and genial in manner; one who thoroughly de- 
tested hypocrisy, and admired the blunt and honest outspoken man, who 
freely expressed his opinion regardless of the consequences. As a 
host, those who have had the good fortune to possess his friendship 
knew him best; and of them it is not too much to say, that they have 
indeed lost a friend whom it will be difficult to replace, and who will 
most assuredly be lovingly remembered by them all the days they 
live. 
Death of Von Baer.—We have much regret in announcing the 
death of this veteran embryologist, the father, we may say, of the
